描述: Understanding Metal Stamping Metal stamping is a cold-forming process that makes use of dies and stamping presses to transform sheet metal into different shapes. Pieces of flat sheet metal, typically referred to as blanks, is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape. Production facilities and metal fabricators offering    stamping services    will place the material to be stamped between die sections, where the use of pressure will shape and shear the material into the desired final shape for the product or component. This article describes the metal stamping process and steps, presents the types of stamping presses typically employed, looks at the advantages of stamping compared to other fabrication processes, and explains the different types of stamping operations and their applications. Basic Concepts of Metal StampingMetal stamping, also referred to as pressing, is a low-cost high-speed manufacturing process that can produce a    high volume    of identical metal components. Stamping operations are suitable for both short or long production runs, and be conducted with other metal forming operations, and may consist of one or more of a series of more specific processes or techniques, such as:     Punching     Blanking     Embossing     Coining     Bending     Flanging     Punching and blanking refer to the use of a die to cut the material into specific forms. In punching operations, a scrap piece of material is removed as the punch enters the die, effectively leaving a hole in the workpiece. Blanking, on the other hand, removes a workpiece from the primary material, making that removed component the desired workpiece or blank.     Embossing is a process for creating either a raised or recessed design in sheet metal, by pressing the raw blank against a die that contains the desired shape, or by passing the material blank through a roller die.     Coining    is a bending technique wherein the workpiece is stamped while placed between a die and the punch or press. This action causes the punch tip to penetrate the metal and results in accurate, repeatable bends. The deep penetration also relieves internal stresses in the metal workpiece, resulting in no spring back effects.     Bending refers to the general technique of forming metal into desired shapes such as L, U, or V-shaped profiles. The bending process for metal results in a plastic deformation which stresses above the yield point but below the tensile strength. Bending typically occurs around a single axis.     Flanging is a process of introducing a flare or flange onto a metal workpiece through the use of dies, presses, or specialized    flanging machinery.     Metal stamping machines    may do more than just stamping; they can cast, punch, cut and shape metal sheets. Machines can be programmed or computer numerically controlled (CNC) to offer high precision and repeatability for each stamped piece. Electrical discharge machining (EDM) and computer-aided design (CAD) programs ensure accuracy. Various tooling machines for the dies used in the    stampings    are available. Progressive, forming, compound, and carbide tooling perform specific stamping needs. Progressive dies can be used to create multiple pieces on a single piece simultaneously.     What is Electrical Fitting?     As you know,the conduit fittings as attachment or accessories for electrical conduit,so we called electrical fitting,conduit fitting or conduit accessories in general.They are used for connect the conduit for easier run the wires in whole house and connect to your electronic appliance.Different conduit has different fitting for connect,you must be pay more attention the size and standard before purchased. The Benefits of Electrical Fittings Maybe you never thought about this issue seriously, but what happens if we don't have fittings?    Easy to Connecting Conduit & Running WireIf you don't have a bend or reducer on hand,you will be crazy.We can't arrange the pipes and wires in a straight line for the whole house which is determined by the geometry.In most cases,it is necessary to turn at the corner and to arrange the wire under or on the wall such as ceiling lamp installed.     However,you need to repair part of the tube sometimes for it is damaged,but you can not replace all of them instead of repair part of a pipe.So the fittings can help you to do this. Good quality conduit can be kept safe of your wire,but it need to match with nice quality fittings too.For example, If you encounter a 90° corner, there is no bend or related fitting on hand.When we run the wire directly and through the pipe, this may cause additional bending and pressure on the wire insulation layer,resulting in whitening of the insulation layer and faster aging.Once the insulating layer fails, there may be a risk of electric shock.     Moreover,a well-sealed conduit will reduce the probability of water and dust entering,which not only keeps the pipe clean, but also protects the safety of the wires.     (3)            Easy to Pull the Wires     If you need to modify the direction or position of the previous wiring for some reason,and we supposed you do not have any special tools.It is the wrong way to pull the wire directly from the right-angle wire tube because this will damage the insulation layer of the wire during the process of pulling the wire,which may cause danger in some cases.Moreover, pulling the wire in this way is easy to get stuck and increasing in construction time.     The Difference Between Hot-Dip Galvanizing And Cold Galvanized     Hot-dip galvanizing and cold galvanized the difference:     1. Galvanizing, also known as    hot-dip galvanized, he is the ingot melted at high temperatures, a number of supplementary material in place, then dipped galvanized metal structure slot, the metal component on a layer of zinc coating    .    The advantages of hot-dip galvanizing corrosion of his ability, adhesion and hardness of zinc coating is better     “Cold plated” or “plating”, ie the zinc salt solution by electrolysis, to the plating on the coating, generally do not have heating, small amount of zinc, the wet environment is very easy to fall off.     2. Hot dip galvanized (galvanizing)     Hot-dip galvanizing    is a chemical treatment, is the electrochemical reaction. Cold galvanizing    is the physical address, just brush the surface layer of zinc, the zinc layer is easy to fall off.    Construction in the use of hot dip galvanizing.     Continuous hot dip galvanizing process: steel    →    heating    →    cooling to the temperature galvanized galvanized    →    cooling    →     Cold galvanized zinc is only 10-50g/m2, its own corrosion resistance than hot dip galvanized a lot of difference.    Galvanized by a relatively cheaper price. Hot dip galvanized steel body is hot dip galvanized surface under the condition of its adhesion strong, not easy to fall off, although there hot dip galvanized pipe corrosion phenomenon, but in a very long period to meet technical, health    requirements.     3. Technological differences     First of all, is the difference between process: hot-dip galvanizing is the workpiece degreasing, pickling, dipping, drying liquid immersion in molten zinc certain period of time, can be raised. Also known as electro-galvanized cold galvanizing, is to use electrolysis devices work piece through the degreasing, pickling ingredients post into the zinc salt solution, and connect the anode electrolysis equipment; in place across parts of zinc plate connected to the electrolysis equipment    positive, power on, use of current from the cathode to the anode of the directional movement of the workpiece will be deposited in a layer of zinc. Zinc finished the difference: no cold galvanized hot-dip galvanizing delicate bright appearance, but the thickness of zinc coating of cold galvanizing aspects of hot-dip galvanizing is a few times.    Galvanized corrosion resistance is also several times.     4. Environmental issues     Fewer emissions of some hot-dip galvanizing. Galvanized pollutants are mainly artifacts of waste acid pickling.     Cold galvanized pollutants include parts of the waste acid pickling, electroplating waste, liquid waste such as passivation. Cold galvanized the type and quantity of pollutants discharged are much more than hot dip galvanizing. Hot-dip zinc standards: GB/T13912-92 Hot-dip galvanizing: hot dip galvanizing process is generally completed after Hemming, when the load is not less than 5mm thick flat steel, the galvanized zinc coating after the average weight of not less than 610 grams / square meter; when the load flat steel thickness    less than 5mm, the galvanized zinc coating after the average weight of not less than 460 grams / square meter, and after galvanizing quality requirements should be consistent with the provisions GB/T13912     What is ADSS Fibre?     All-dielectric self-supporting    (ADSS) cable is a type of    optical fiber cable    that is strong enough to support itself between structures without using conductive metal elements. It is used by    electrical utility    companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors.     ADSS is an alternative to    OPGW    and    OPAC    with lower installation cost. The cables are designed to be strong enough to allow lengths of up to 700 metres to be installed between support towers. ADSS cable is designed to be lightweight and small in diameter to reduce the load on tower structures due to cable weight, wind, and ice.     In the design of the cable, the internal glass optical fibers are supported with little or no strain, to maintain low optical loss throughout the life of the cable. The cable is jacketed to prevent moisture from degrading the fibers. The jacket also protects the polymer strength elements from the effect of solar ultraviolet light.     Using single-mode fibers and light wavelengths of either 1310 or 1550 nanometres, circuits up to 100    km long are possible without repeaters. A single cable can carry as many as 864 fibers.     What is overhead line fitting?     Overhead line fitting is a wide range of steel fittings that are used to construct the overhead line，it is used to hang, connect or protect conductors or insulators.Overhead line fitting is also called overhead line hardware or overhead line accessories.According to the function, overhead line fittings can be divided into:

描述: Top 3 Methods For How To Clean Stainless Steel Jewelry Do you have some stainless steel jewelry but aren't sure how to get it looking clean and like new? Stainless steel has a lot of great benefits when used to make jewelry and makes for a great alternative to other jewelry metals. Today, stainless steel is an incredibly attractive and affordable jewelry metal for wedding bands due to its durability, scratch resistance and continued luster. (Check out our blog    Best Online Jewelry Store For Engagement Rings & Wedding Rings!) Consider these benefits to using stainless steel for jewelry: 1 Super Strong.Finished stainless steel jewelry    will retain its shape, will not readily warp, nor will it easily lose its fine detail to nicks or scrapes. Stainless steel jewelry items with a brushed or satin finish will retain their luster longer, as well. Its strength and durability also makes stainless steel resistant to scratches. 2 Resistant to Rust, Oxidation & Discoloration. Stainless steel is a relatively corrosion-resistant when compared to other jewelry metals. For those living in high-humidity locations, stainless steel is highly recommended as this metal will keep from rusting much longer than other kinds of metals. 3 Great Alternative For Those with Allergies or Sensitivities. Unplated stainless steel jewelry is one of the best options out there for those with allergies or skin sensitivities. Copper or brass jewelry should be avoided for those with allergies or skin sensitivities. Though stainless steel can contain some nickel, it is commonly considered hypoallergenic for most people. To learn more about how to clean stainless steel jewelry, keep reading!! We've got a lot of great tips on how to clean stainless steel rings, the best stainless steel jewelry cleaner, and how to clean stainless steel jewelry at home. For more information about how to clean other kinds of jewelry, check out our    Complete Guide: How To Clean Jewelry.        Pros and Cons of Stainless Steel Stainless steel is a well-known material used to make everything from cooking utensils to car parts. An alloy that mixes elements like chromium, titanium, and nickel, its silvery finish also makes it a popular commodity in jewelry design. Stainless steel not only mimics the look of fine, precious metal, but baubles made of this material are much more affordable. When it comes to rings, those made of stainless steel are a smart choice for everyday wear since they will be durable and strong. However, there are pros and cons to be considered before slipping that new ring onto your finger. ADVANTAGES Stainless steel is a highly durable metal, allowing it to withstand the wear and tear of everyday activities, which can otherwise damage a ring. The hard metal resists scratches and corrosion thanks to an invisible layer of chromium that prevents oxidation; this makes it a wonder metal of choice for body jewelry.    Maintaining stainless steel jewelry is also a lot easier as you won't have to have special cleaning solution to care for your wholesale jewelry. Just use warm water, liquid soap, and a little bit of elbow grease and your stainless steel ring will be good as new.    Because it is not a precious metal such as gold, silver or bronze, it's very affordable, making stainless steel pieces quite budget friendly. DRAWBACKS Despite its durability, stainless steel rings can dent. Compared with precious metals, only silver dents more than stainless steel. Sizing a stainless ring can be difficult because the metal is hard, rigid and stiff. This rigidity also makes it challenging for jewelers to set gemstones. Additionally, stainless steel can sometimes include nickel, which can be problematic if you have a nickel allergy. Although people with nickel allergies have successfully worn Oooh! Shiny Things jewelry without any issues, the severity of allergies differ from person to person so it is still advised to use caution when purchasing stainless steel and purchase at your own risk if you have a nickel allergy. Initial Necklaces for Each Letter in the Alphabet Initial necklaces    are among the best baubles for personalizing a jewelry look. From delicate chains to bold pendants and glittering diamonds, there are endless options for customizing your neckline, whether your metal preference is white or yellow gold, silver, or so-modern rose gold. Of course, birthstone, charm, and astrological jewelry are other stylish personalized adornments. Yet, there's nothing quite like a metal-worked or diamond-encrusted A, B, or C to showcase your favorite letter or initials.     Some of the most popular and easy-to-wear initial necklaces are dainty and often rendered in script, block, or gothic letters. At the same time, baguette stones, glittering pavé, and oversized letters amount to bolder initial jewelry moments. Of course, gemstones, pearls, and enamel touches make for a more striking lettered necklace too.     When worn alone in all its glory, you'll glean more of a minimal look from an initial necklace. Or you can take things in a maximalist direction by combining several letters on the same chain or layering several to represent your first and last name, a favorite word, or the initials of loved ones. As a playful homage, why not don a strand with your pet's name, a favorite mantra, or a nickname? Whatever your preference—and we highly recommend owning an assortment—you can layer all types of initial necklaces beautifully, like with other chains, charms, and pendants.     Don't forget, initial necklaces also make extraordinary gifts for birthdays, holidays, or to celebrate special events like a wedding (new last name, who this?) or the birth of a baby.     From affordable jewelry finds to lust-worthy fine designs, scroll on for Vogue's edit of the very best initial necklaces representing each letter of the alphabet.        What is a pendant in jewelry?     Pendant, in jewelry, ornament suspended from a bracelet, earring, or, especially, a necklace. Pendants are derived from the primitive practice of wearing amulets or talismans around the neck. The practice dates from the Stone Age, when pendants consisted of such objects as teeth, stones, and shells.        The pharaohs of ancient Egypt wore pendants that were sometimes of huge dimensions, usually bearing commemorative or auspicious scenes in which the sovereign is being deified. Other pendants were in the shape of flies, winged scarabs, vultures, the eye of the god Horus, falcons, and sacred serpents. An exquisite example of an early gold pendant is that of two hornets clasped together, found in Mycenae and dating from the 17th century BCE. Etruscan pendants were decorated with spindles and cylinders, figured, or in the shape of human heads. Greek and Hellenistic pendants usually formed the entire necklace. Pendants in the shape of a bulla are frequent in Roman necklaces, but there are also examples of cameos, intaglios, and gold coins mounted as pendants.     During the Middle Ages, characteristic jewels were the reliquary, or devotional, pendant and the cross, chased or enamelled with religious subjects and often set in an architectural frame. One of the most famous early pendant reliquaries, which belonged to Charlemagne, contained relics of the True Cross and the crown of thorns under a sapphire set with gold. In the 14th century it was customary for noblemen to wear necklaces with pendants bearing heraldic subjects; pendants worn by women generally depicted sentimental subjects.     Toward the beginning of the 16th century, pendants became decorative rather than religious objects. The Renaissance artists created numerous beautiful crosses and figured pendants modelled in high relief and depicting numerous subjects, such as mermaids, tritons, animals and ships, and mythological and religious scenes. Often, the irregular shapes of baroque pearls were exploited and adapted for the bodies of human beings or animals, whose faces and limbs were modelled in gold and enamelled.     Should I buy a Zirconium ring? Pros and Cons     As Jewelry Shopping Guide editors, we write about things that we love and we think you'll like too. We often have affiliate partnerships, and may generate some revenue from these links at no cost to you.     Gone are the days when the only 3 viable materials for rings and wedding bands were just gold, silver, and platinum. Nowadays, with the advancement of modern technologies, the industry has harnessed and created many other great metallic and non-metallic materials that make for excellent wedding bands. And one of them is zirconium.     This fascinating material has wide-ranging applications and is excellent in use for industrial purposes like nuclear reactors as well as in jewelry. Be careful not to confuse zirconium with zirconia, however, as the latter – also known as Cubic Zirconia – is a man-made material with very different characteristic.     So, what exactly is zirconium and why should you consider it for your wedding band?     What Is A Zirconium Wedding Band?     Zirconium is a natural element that is usually derived by purifying other minerals such as zircon with chlorine. This means that zirconium isn't found in its “native form” but needs to go through an extraction process. Fortunately, the purifying process is inexpensive and allows for large quantities of zirconium to be produced at a very low price.     After it gets produced in this manner, zirconium has a silver-ish or greyish color at first. However, it's typically heat treated and exposed afterward in order to oxidize the metal and give it a rich black color. This is one of the main draws of zirconium as most metals can only achieve such a black color through plating or antiquing which tends to fade over time. The black color of heat treated Zirconium, on the other hand, doesn't fade, doesn't tarnish, and doesn't change color – it's permanent. After going through this treatment, black zirconium gets a very nice feel as the oxidized top layer feels like ceramic while also being as hard as sapphire. The surface can be given various finishes, such as brushed, hammered or polished.

LED panel lighting delivers a smooth and flawless wall of illumination without visible bulbs or hot spots.Their versatility allows them to be mounted on numerous surfaces and used in multiple applications.    Whether you want to    replace your existing T8 fluorescent troffer light fixture    or start a new construction project, panel lighting is an innovative and energy efficient alternative.    How does LED panel lighting compare to traditional fluorescent or incandescent light bulbs?Acrylic Light panels are much more durable than your traditional light bulb and longer lasting. LED panel lights can last up to 17 years, assuming usage is around 8 hours a day, while an incandescent light bulb or fluorescent light will only last a fraction of that time.    Compare CFL's vs. Halogen vs. Fluorescent vs. Incandescent vs. LED They come in a variety of brightness and wattage, which makes them great for kitchens, hospitals, offices, gyms, schools, and so much more. Although LED light bulbs seem to be all the hype right now, commercial contractors are moving towards LED panel lighting for their sleek and modern look. What is the difference between an LED Troffer and a LED Panel? LED panels are used to replace your existing fluorescent ceiling lights. They require less space due to their slim profile and straight edge. LED troffers, however, are rectangular light fixtures that are designed for a modular dropped ceiling. They generally require more space for installation, but can come in a variety of style options.    How Long Do Solar Lights LastIf you recently bought some solar powered LED lights, then you must be wondering how long do solar lights last.Well, if you are looking for an in-depth answer, then this article is specially made for you. In this article, we will cover how long do solar outdoor lights last, how long does it take them to charge, and how many hours will they stay on.So without further ado, let's jump right into it. The short answer is    1-5 years    depending on many factors such as    weather,    quality,    usage, and many more. However, to properly answer your question, here is a list of the life expectancy of the    3 main    solar lights components: Solar LED Lights’ panels lose their efficiency over time depending on    3 factors:    usage,    conversion efficiency, and    efficiency loss per year.For example, a    Monocrystalline Solar Panel    has a conversion efficiency of around    23.54%    and an average output loss of    0.8%    a year. This means that within    29.3 years, this solar panel will be dead. Generally speaking, most solar panels last between    10-30    years before they become useless.The Ultimate Guide to Underwater Video LightsThere are two types of lighting which are used underwater: Strobes (AKA flashes) and Video Lights (Constant LED Lights).    Underwater Video Lights are more popular than strobes since they allow shooting both video and stills.     After creating the    Ultimate Strobe Guide, we wanted to share our thoughts on the second type, and help you choose the best underwater video light for your needs.     If you want to skip directly to the recommended video lights section,    click here    (Updated May 2021).     When trying to choose which    underwater video light    to get, you should consider the following features: Lumens    – How strong the video light is. Beam Angle    – How wide or narrow the beam is. Controls    – Which buttons / dials / levers are used to operate the light.Modes and Levels    – Which modes are available and how many power levels.Beam Quality    – Is the beam nice and even or does it have hotspots. Mounts    – Which mounts does the light come with.Batteries and Charging    – How long does the battery last, how fast does it charge. Price    – No explanation needed    Before we dive into these features in detail… What is an underwater video light? Strobe, Flash, Flashlight, Torch, Video Light… HELP! Let’s set things straight. As we mentioned, there are only 2 types of lighting underwater:     Strobe    – A Xenon    based light bulb which can emit a very strong pulse of light for a brief moment. Also known as a “Flash” (not flashlight!)     Constant light    – A device which can emit a constant beam of light for minutes to hours, today commonly based on    LED technology    which can be focused to perform as a dive light or spread out to perform as a video light. Also known as “Torch”, “Flashlight”, “Dive Light”, “Video Light” and unfortunately even “Strobe” in the topside industry, which is incorrect for the underwater photography lingo.     An underwater    video light    is basically a waterproof flashlight. There is some confusion due to the use of the word “flash” in “flashlight”, but don’t let linguistics    mess with you. “Flash Light” and “Flashlight” are two different things!     Now that we got that out of the way, we’ll continue to discuss video lights!     Bulkhead lighting explained     Bulkhead lighting may not be the first thing that springs to mind when it comes to sprucing up the exterior of your house. Although generally thought of as a functional light bulkheads can in some cases add real character to your home or business premises.     For some, the word bulkhead may bring to mind a wall inside the hull of a ship, or within the fuselage of an aeroplane, which is one of the word's other meanings. However, when it comes to lighting your home, garden or commercial property, the term ‘bulkhead'    refers to a very specific type of light.     Bulkhead lights provide a robust style of lighting for outside areas and large indoor spaces. They're often used by businesses and in industrial areas where bright light is needed constantly. Bulkhead lights are designed to be tough enough to withstand dust, water and even acts of vandalism. They provide large amounts of light which in itself can act as a deterrent to vandals and thieves. It's because of their durable design and impressive lighting ability that you'll find bulkhead lights in underground car parks, on outside walls, and inside warehouses and large commercial buildings.     Bulkhead lights are also a useful security addition to the outside of your house and perfect for garage lighting. They also make dark garden pathways safer and easier to navigate.     What is a magnetic track lighting System?     Recently years, with the rise of simple style, more and more decoration choose linear lighting. The linear lighting fixture can match different decoration effects according to different spaces, which can simplify the color and shape under the premise of meeting the basic lighting functions. Very creative and fashionable. In this case,    the magnetic lighting system    which combines all linear led lights emerges as the times require, and there is a trend to replace the conventional led track lighting and the conventional linear lamp in the future.     Magnetic led light    is a way to attach the led lighting assembly to the track by magnetic absorption. Under the condition of a reliable power connection, it is more convenient to install and dismantle the lights assembly, and also convenient for daily maintenance and repair, and the power connection is stable and reliable. It can be flexibly matched with different types and quantities of track lights according to various requirements. If the power is allowed, it can be arbitrarily spliced to the track for use. A magnet track can support different led lights, so it can be used in a wider range of applications. It can slide to any position easily without any auxiliary tools. Different splicing methods are realized. It can be equipped with different ceiling lights. Magnetic led light adopts modular concept, which can be applied to many light source modules of the magnetic suction lamp, including downlight, spotlight, grid lamp, magnetic light bar, recessed linear lighting, etc. The light source can be freely selected and DIY can be used to meet the lighting requirements of different spaces.         The number of    light fixtures can be increased or decreased freely. There is no limit to the number of lamps and lanterns installed on the track. If the light intensity is not enough then just Increasing the magnetic rail lights onto a rail. If the brightness is too high, then take fewer led lights.         It can move freely and adjust the angle freely On the magnetic track, the lights can move freely, and the lamp can be arranged freely according to the space demand. Besides, many of the magnetic led lights are adjustable angles, including the magnetic track spotlight, magnetic grille light, etc which increases the degree of freedom of light design.         Low-pressure safety, no-touch hazard. Generally, the magnetic track lamps on the market are designed with a low voltage of 24V or dc48V. even if the track is always electrified, there is no danger for manual touch and installation of lamps. Of course, there is a magnetic track light 110VAC 220VAC available in markets.

It has also been used by various high-end brands as the packaging of its luxury series of glasses. So, as the professional glasses case manufacturer in China for more than 10 years, today ISUNNY will explain some relevant knowledge points to help more people know about it.     1. What is a handmade glasses case?     As the name implies, this type of spectacle case is all made by hand. Of course, with the advancement of technology, more and more production processes will be slowly replaced by mechanization, such as cutting, gluing and logo production.        2. The production process of the handmade eyeglass case     When the raw materials are bought back, we will cut them according to the size and graphics of the glasses case, and then transfer to the glue spraying process; after the glue dries, we start to paste the fabric part and then wrap the edge of the glasses case (also called Hem). The next step is to produce the logo according to the customer's requirements. After the logo details are processed, we will fix the lining. After the above steps are completed, we are going to undergo plastic surgery to perfect the shape of the glasses case. The last step is to carry out quality inspection and packing (of course we are not only in the last step of quality inspection, but we also start from the first step of raw materials in, and carry out the inspection, and accompanied each step of the entire production process)     3.Classification of the handmade eyeglasses case     A. General handmade glasses cases are divided into regular and special-shaped handmade glasses cases. The regular hand-made glasses case refers to the triangular and square or rectangular glasses case, and the irregular shape refers to the round or arc or stepped glasses case. Regular hand-made spectacle cases are relatively cheap due to the large part of the machinery involved in the production. On the contrary, all or most of the special-shaped spectacle cases are completed by hand, so the price will be more expensive.     B. Handmade glasses cases are also divided into foldable and non-foldable glasses cases. Normally, foldable glasses cases refer to triangular and square or rectangular glasses cases. The advantage of the folding glasses case is that it is convenient for users to carry around because when you take out the glasses from the glasses case, you can easily fold the glasses case into the bag, even in the pocket of clothes or pants It doesn't take up volume either, is it perfect?     C. According to the size of the eyewear case, we can divide the handmade eyeglass case into sunglasses case, optical glasses case and reading glasses case.     Because of time constraints, we will close here today. Next post we will tell you which fabrics can be used for handmade glasses cases, what materials can be used for the support part of handmade glasses cases, what logo process can be done for handmade glasses cases, and whether you can customize your own size and shape.     If you have any other questions about the above points, please leave a message in the comment area below, and we will give you a detailed response as soon as possible.     Barrel Hinge     The    hinge    is the only moving part on an eyewear frame. The hinge helps keep the frame tight, takes the brunt of many impacts and allows the    temples    to fold in or out.    Therefore, a high quality hinge will prolong the life of the frame.     A barrel hinge is one of the most popular hinges to feature on eyewear. A barrel hinge is the one with 'loops' and a screw through these loops. The 'loops' are the barrel. The amount of barrels usually depend on the thickness of the temples. The thicker the temple results in more barrels. This is to strengthen the hinge. Barrels typically come in intervals of either 3, 5 or 7. Some of the barrels are fixed to the temple and the others to the rear of the    end pieces. The advantages of a hinge barrel are, added durability and a strong mechanism. The disadvantages are over time the hinge made become loose, rust and on some occasions the screw pop out of the mechanism.     The Pros and Cons of Reading Glasses     Have you been worrying if you'll soon need to buy a pair of reading glasses? Are these letters getting a little fuzzy? Don't be scared if you start realizing you can't read up close. Don't panic! This is something that a lot of people start realizing sometime in their life, whether they're young or old. If you see that you need to stretch your arm more and more to be able to focus on the words it might be a sign that you need reading glasses. But that is not always the case!     Help, I Can't Read Up Close!     The first thing we advise you to do is set up an appointment with an ophthalmologist. Have a full eye exam. Are you having headaches? Are you tired? There are a lot of circumstances that inhibit you from properly focusing on up close reading. You might not necessarily need reading glasses.     The Pros and Cons of Reading Glasses     Once you make an appointment with at your local optometry office they can give you an idea of what might be happening to your vision.     Often times headaches and nausea can result from wearing the wrong prescription of readers or may have optical centers far from your pupil centers.     This is why we recommend having an eye doctor specialist do an eye exam. These are a regular recommendation even if you don't experience regular problems with your eyesight.     Reading Glasses Don't Deteriorate Your Eyesight     Yes, you can become more dependent on using them, but if you notice your eyesight getting weaker over time it is not because of you wearing reading glasses. Your eyesight naturally fades and falters as you grow older. Many people develop presbyopia during their middle and old age years.     ‘Readers'    Help Improve Your Vision     Unfortunately we haven't invented glasses that fully correct eye problems, they only help eyesight. Take extra measures to protect your eye health because once damage is done, it becomes harder to repair it.     Glasses or Contact Lenses?     Reading glasses are cheaper, safer, and often times cleaner. They cost less and they don't have to be replaced as often. Glasses are used externally, so you don't have to risk poking your eye or causing a possible eye infection. They also require less maintenance overall.Even though it could mean bad news that you need to wear reading glasses, think about all your new style options and the wrinkles you'll avoid by no longer squinting.

描述: Types of Stretch Film There are many brands and configurations of stretch wrap film in the market today, as a matter of fact there are too many and its confusing to say the least.Broken into two main categories of Hand Stretch Film and Machine Stretch Film depending on how the product is applied the rest of the variations are focused on gauge, manufacturing and application. What is Hand Stretch Film?Stretch film designed specifically to be applied manually is referred to as hand stretch film. It is also referred to as hand film, hand stretch wrap, hand wrap or manual pallet wrap. It is typically utilized in lower volume packaging operations. However the efficiency of manual stretch wrap packaging should be regularly re-evaluated against potential benefits of upgrading to a machine applied films. Choosing the right stretch applicator will result in more efficient and cost effective packaging operations.What is Machine Stretch Film? Stretch film designed to be applied with a stretch wrap machine is referred as machine stretch film. It provides many advantages over hand film including: faster and more efficient packaging, reduced packaging material costs, safer application, more secure loads and more. Common Machine Stretch Film TypesBlown Stretch FilmCast Stretch FilmPre-stretched FilmSpecialty Stretch FilmThe basics of the stretch wrap world are that the heavier your load and the farther it travels the more film you will require to secure it. With this in mind the process requires knowledge, experience and expertise to select the most cost effective solution for your shipping requirements. What is Cast Stretch Film?Cast Stretch Film, otherwise known as Cast Film or Cast Wrap, is manufactured using the cast extrusion process.Typical Characteristics of Cast Stretch Films Excellent OpticsClear Glossy         What are Pre-stretched Films?Pre-stretched film is film that has been stretched (or pre-stretched) during the manufacturing process and then rolled onto cores for customer sale. Pre-stretch Film Benefits:Safer and easier operator application Reduced neck down eliminates revolutions and trips around the pallet Lighter rolls reduce operator fatigue and staff loss time injuriesPre-stretch films are recyclablePre-stretched film is strong, consistent and stable What are Specialty Stretch Films?Specialty stretch films are designed to answer very specific packaging needs that more general purpose stretch packaging products cannot accommodate. A small sample of some specialty stretch packaging films are below.UVI Stretch WrapVCI Stretch WrapRoll Wrap Film Wide Web WrapPallet Wrap NettingTinted Stretch FilmHeavy Gauge FilmBundling Film Vented Pallet WrapBanding Film Opaque Black StretchWrap Anti-static Stretch WrapFlexo Printing Equipment for Industrial Products Flexographic printing is a method of direct contact printing.    A flexographic (flexo) printer consists of multiple wheels that work in unison to pick up ink from an ink reservoir, deliver the ink to a printing die or plate, and roll the ink onto the material being marked.Flexo printers are an excellent choice for these types of printing applications:The printed message does not change often High quality logo printing is desired Printed logos or messages are large Specific colors are required (e.g. Pantone colors)Printing is only required for short production runsThe budget for printing equipment is limited         Simple/low-tech printing machines are desiredIndustrial Printing Applications Pannier flexographic printers are used for printing text and high resolution graphics on flat materials such as metals, rubber, building products, textiles, and packaging products.    The most important consideration when purchasing a flexo printer is the requirements of the printed message(s). How large is the overall size of message to be printed?    How often must the message repeat on your material?    The answers to these questions will determine the width and circumference of the print drum needed for your printing job.     The    Pannier Super Ink Print-All    uses a universal frame that can accommodate wheels of several different circumference sizes. As shown in this image, the same size message can be printed with three different print wheels, but increasing the circumference of the wheel increases the space between each repeat of the print.     Flexo printers use either one or two rolls to pick up and apply ink to the print wheel which holds the printing plates or dies. The wheels are tied together with a chain and sprockets so that they turn in unison. The friction of the print wheel making contact with the moving material is what drives the rotation of all the printer's wheels.     Types Of Paper Used For Making Paper Bags     If you're thinking of the most inexpensive way to package gift items for your clients or colleagues, think paper bags. Even better, go for paper bags that are environmentally friendly to show your sensitivity to conserving the environment.     Paper bags can be used for a variety of purposes, which include packaging food in snack bags or packing promotional items together to make gift bags. Paper bags don't have to be bland. They can be beautifully designed using exciting colours to give them a touch of flair and style.     The ideal paper for making paper bags depends on what you want to do with the bags. Aesthetics, smoothness and toughness are some of the qualities desirable in a paper bag, and so the material used must be appropriate for the type of paper bag you have in mind.     Regardless of the material you choose, branded paper bags are handy marketing tools that can carry a company's brand and logo to places the traditional marketing strategies cannot reach. As you consider the various types of paper bags on offer, think of what you want to package in them, the message you want to send, and, of course, the aesthetics. Kraft paper is a commonly used type of paper for paper bags. This material is made of softwood sulphate, a thick light-brown, yellowish-brown, white or cream paper-making material with a weight of between 80 and 120 grams. The tensile force of kraft paper is high. It comes in variations of no-grain, single or double light, or stripes. It's used to primarily package envelope bags, portfolios, medical records bags, and so forth. It’s also ideal for packaging food takeaway.     This material features a combination of a single layer or multi layers comprised of fully sized, bleached chemical pulp. Its texture is firm while the surface is smooth. Among the various paper bag-making materials in the market, imported white cardboard is more widely used.     If you're looking for top-of-the-range gift boxes or bags, they will most likely feature imported white cardboard. These make for very appropriate giveaways or promotional items for clients who expect a slightly higher quality.     This material is ideal for making cartons, labels, cigarette cases and other types of packaging. Paint and copper plate base paper are the main materials used. Auxiliary materials, adhesives, and pigments are converted into coatings to cover the paperboard's surface using special equipment.     They are then dried and calendered, leaving behind a clean, smooth surface that makes for a superior printing performance. The grammage (paper thickness or weight) is between 70 and 250 grams.     Advantages Of Square Bottom Portable Paper Bag Machine     The square bottom portable paper bag machine is mainly used for clothing product packaging, boot product packaging, various gifts, corporate image promotion bags, etc. What is the development trend of portable paper bag machine? There are two main types of hand-held paper bag machines on the market: one is a roller hand-held paper bag machine; the other is a one-piece hand-held paper bag machine.     Both devices have the characteristics of automatic paper feeding, automatic gluing, automatic bottom paste and automatic output.     However, there are still some disadvantages.     First of all, after the finished paper bag is finished, there are dents on the front of the paper bag, which affects the appearance of the product.     Second, the finished paper bag needs to be manually laid on the bottom of the bag with bottom paper to improve the bottom strength of the paper bag.     Third, the handle of the paper bag needs to be attached manually.     Fourth, the production efficiency is low, about 40-60 per minute.     Fifth, the range of suitable paper is limited, and the paper weight is between 70-200g/m2.     Because the square bottom portable paper bag machine is easy to carry and easy to degrade, it can not only recycle recycled paper, but also reduce air pollution and is environmentally friendly, so it has become one of the most useful green products.     The development of paper bag machinery shows a trend of combining mechanical, electrical, gas, liquid, optical and magnetic properties into one. It has become a trend to produce high-efficiency, energy-saving, recyclable products, high-tech practicality and intelligence.     Types of Paper Bags     With the wide range of paper bag sizes available, it can be hard to pick the product that best suits the needs of your business. Keep reading to learn more about the distinctions between different bags.     paper grocery bag     Brown vs. White Paper Bags     Paper bags generally come in two colors: brown and white. While brown paper bags are used more frequently than their white counterparts, white bags will highlight your establishment's logo and present a cleaner appearance than brown bags. Regardless of the color you choose, all of these products feature a thick construction that's resistant to tears and rips.     Which Paper Bag is Best for Your Business?     If you run a restaurant or small deli, paper lunch bags or shopping bags with handles are a useful choice for your business. Additionally, grocery stores usually need heavy weight paper grocery bags and sacks. Liquor stores can use beer, liquor, and wine bags, while merchandiser bags work well for boutiques or bookstores. If you run a produce stand or farmer's market, we recommend produce and market paper bags. Finally, paper bread and recloseable coffee and cookie bags are a great choice for bakeries and cafes.

描述: How to Source and Select in a Natural and Sustainable Way: Royal Jelly Example     Manual harvesting is essential to ensure the best sourcing, while environmental sustainability and bee-friendly practices are fundamental to securing societal responsibility and transparency. Not all products on the market offer the same quality and characteristics and an easy way to determine the best product is its production method. ISO 12824:2016 specifies both the production and sanitary requirements for Royal Jelly. It also lays down a series of organoleptic and chemical test methods to control Royal Jelly quality.        10-hydroxy-2-decenoic acid, best known as 10-HDA, is the most famous and studied active ingredient of Royal Jelly. According to research, 10-HDA has immunomodulatory activity and antibacterial action. Nevertheless, 10-HDA content may be different across products, influenced by several parameters, especially during production, transport and storage process. Since 2016, ISO 12824 defines a minimum 10-HDA content of 1.4 g for 100 g of fresh Royal Jelly. This minimum content    equals the quantity present in natural Royal Jelly. It is important to respect the nutritional balance of the product to benefit from its health properties     It is important to study test results for contaminants when it comes to choosing a Royal Jelly. It may be certified as organic if it meets set criteria from the European Commission—pollen, nectar and honey as a unique source of food for bees are essentials without pesticides, heavy metals and antibiotics. ISO 12824 distinguishes also two qualities of Royal Jelly, determined by the feeding practices for the worker bees. If they were exclusively fed with pollen, nectar or honey, the Royal Jelly is known as type 1. Using sugar syrups of proteins leads to a type 2 designation. For an organic product, choose a type 1 Royal Jelly. Determining type 1 is possible by analysing the data sheet: Royal Jelly type 1 presents a C13/C12 ratio of isotopes between -29 and -20. It has also regulated rates of sucrose (< 3 percent), erlose (< 0.5 percent), maltose (< 1.5 percent) and maltotriose (< 0.5 percent).     Use certifications as a way to demonstrate to consumers what you are doing. This is your chance to differentiate yourself with for the best traceability and supply chain insights.     Potential Health Benefits of Royal Jelly     Royal jelly is a gelatinous substance produced by honey bees to feed the queen bees and their young.     It’s frequently sold as a dietary supplement to treat a variety of physical ailments and chronic diseases.     While it has long been used in traditional medicine, its applications in Western medicine remain controversial.     Royal jelly is comprised of water,    carbs, protein and fat.     The full chemical makeup of royal jelly is unknown, but its positive effects on health are thought to stem from its unique proteins and fatty acids (1,                2Trusted Source     ).     These include nine glycoproteins collectively known as major royal jelly proteins (MRJPs) and two fatty acids, trans-10-Hydroxy-2-decenoic acid and 10-Hydroxydecanoic acid (             2Trusted Source     ).     Royal jelly also contains several    B vitamins    and trace minerals.     However, nutrient composition varies considerably between sources of royal jelly.     Royal jelly is widely claimed to    reduce inflammation    and oxidative stress.     In multiple test-tube and animal studies, specific amino acids, fatty acids and phenolic compounds found in royal jelly appear to have potent antioxidant effects (             3Trusted Source     ).     Additionally, several test-tube studies show reduced levels of pro-inflammatory chemicals released from immune cells treated with royal jelly (             4Trusted Source     ,                5Trusted Source     ,                6Trusted Source     ).     While these results are promising, human studies are lacking. More data is needed to draw any definitive conclusions on treating inflammation with royal jelly.     Both animal and human studies demonstrate that royal jelly may positively impact cholesterol levels and thereby reduce heart disease risk.     Though the exact mechanism remains unclear, specific proteins in royal jelly may help    lower cholesterol    (             7Trusted Source     ).     One 12-week study found that rabbits supplemented with royal jelly significantly reduced their total and “bad” LDL cholesterol levels by 28% and 23%, respectively (             8Trusted Source     ).     Similarly, a one-month human study saw an 11% and 4% reduction in total and “bad” LDL cholesterol levels in people taking about 3 grams of royal jelly daily (             9Trusted Source     ).     Conversely, another small human study determined no significant differences in cholesterol levels between participants treated with royal jelly and those on a placebo (             10Trusted Source     ).     While these studies are promising, more research is needed to better understand royal jelly’s impact on heart health.     Advantages of Propolis Extract     A Natural Antioxidant as ‘Nature’s Best Defence’. Propolis has very high levels of bioflavonoids and other bioactive compounds providing immune support     Happy Valley’s NZ Propolis Extract 15% is one of our most popular Propolis products. It is easy to use, water-soluble    and ideal for people who want the full health-giving benefits of Propolis without alcohol.     Propolis is a natural resin found in the young buds of trees. Bees collect propolis, mix it with their own enzymes and    beeswax, and use it to seal the hive. This creates the most sterile environment known in nature and protects the hive against disease.     How to use Propolis Extract (15%):     Add to water & gargle Add to drinks or    food Apply directly    Inhale it through steam     Evaluation of the Immunomodulatory and Anti-Inflammatory Activities of Honey Bee Larva Powder     Honey bee larva powder (HLP) has traditionally been used as a daily supplement and tonic for health promotion with an uncertain scientific basis. In this study, B16-F10 tumor-bearing mice were established to evaluate the immunomodulatory activity of HLP. The proliferation and apoptosis assays were performed to evaluate the anti-inflammatory activity of honey bee larva extract (HLE) in RAW 264.7 macrophage. The    in vivo    experimental results demonstrated that the oral administration of freeze-dried HLP (4 and 6 g/kg) significantly enhanced the spleen index, the percentage of CD4+cells, and the ratio of CD4+    and CD8+    T lymphocytes (CD4+/CD8+) in the peripheral blood compared with those in the tumor control mice. The    in vitro    studies demonstrated the potent immunomodulatory activities of HLE through the induction of RAW 264.7 macrophage proliferation and the mitigation of doxorubicin (DOX)-induced toxicity. HLE also exhibits anti-inflammatory activity by decreasing the production of nitric oxide (NO) and the cytokine level of interleukin-6 (IL-6) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage. The present study provides important scientific evidence for the immunomodulatory and anti-inflammatory activities of HLP and HLE.     Honey and Vinegar: Are There Health Benefits?     Drinks made of honey and vinegar have existed for thousands of years. Also known as “oxymel,” the combination of honey with some kind of vinegar creates a syrup that’s usually added to water or another liquid and then drunk. Since ancient times people have used the mixture to prevent or improve many conditions:     Honey and vinegar are both rich sources of vitamins and minerals. For instance,    vitamin C    and    vitamin E    exist in honey, while vinegar contains    vitamin B-12    and    vitamin K.     Vitamins help the body function and stay healthy. The vitamins in honey and vinegar boost the immune system, aid in bone and heart health, assist in memory and cell production, and help blood clot.     Research has found a number of potential health benefits to eating or drinking honey and vinegar:     Disease Prevention     Honey and vinegar contain    antioxidants, which play an important role in    reducing harmful oxygen molecules    (called    free radicals) in the body. Antioxidants help lower your risk of developing certain diseases such as    cancers, as well as reduce signs of aging and combat types of    dementia.     Improved Heart Health     Some studies suggest that consuming vinegar may help prevent heart-related diseases. In particular, vinegar has been linked to lowering levels of        “bad”    L    DL cholesterol    and increasing levels of        “good”    HDL    cholesterol, which the body uses to help protect against heart disease.     Meanwhile, early studies suggest that taking in moderate amounts of honey may help    lower blood pressure, which is another risk factor for heart disease.     Finally, a few early trials also suggest that vinegar generally lowers    oxidative stress    in the body, which is a predictive factor for atherosclerosis (the hardening of the heart’s arteries). More research exploring the effects on humans is needed.        Weight Maintenance     Vinegar has also been connected to a    reduction in appetite, although accuracy of this claim is debated. Many believe the acid in vinegar slows the absorption of food in your digestive system, leaving you feeling fuller longer. As a result, consuming honey and vinegar may allow you to more easily maintain your weight.

描述: Surface Laser Cleaning RUST REMOVAL / DEOXIDIZINGIndustrial laser cleaning systems are most known for their rust removal capabilities. Application can be found in multiple industries as for example process & production or the heavy industry. Our laser systems can be used to derust or deoxidize small machinery or materials which leave the warehouse rusted after being left there for several weeks or months. Some of the main advantages of using laser cleaning as a rust removal method are the lack of chemicals that have to be used, the substrate is not damaged, very little pollution, etc. COATING REMOVALA lot of our customers use the laser's coating removal capabilities prior to any welding, brazing, bonding or new coating process. In the heavy industry for example, laser cleaning is used to prepare train bodywork for a new coating. Our systems are also capable of removing the paint layer by layer, if you don't want to remove everything all at once. The laser technique is a non-contact/non-abrasive process, no use of chemicals or blasting media are necessary , we see a reduction in waste, automation is easy and it's very safe. RESTORATION In the restoration process, laser cleaning has been used with satisfying results in for example stone conservation to remove encrustation. Alongside the aesthetically pleasing results, it is relevant to determine that laser cleaning does not have any adverse effects.     Compared to the more traditional techniques, laser cleaning has many additional advantages. The diameter of the laser beam can be regulated so that areas of different dimensions can be treated. There is no physical contact between the object to be cleaned and the laser equipment. This aspect can be really relevant in treating fragile materials.  NON-DESTRUCTIVE TESTING Non-destructive testing is the technique, used in the technology industry, to evaluate the properties of a material, component or system without causing any damage to the base material. Laser cleaning can remove dirt, rust or any other contaminant from the base material, without damaging it. Because of this, laser cleaning is a perfect solution if NDT has to be performed. SPOT REPAIROften not the complete surface has to be cleaned, but only certain spots on that surface. Imagine you only have to remove rust on certain spots on a weld or that you only want to clean the rivets on the body of an airplane. That's where spot repair comes in and because of the 2D-scanners in the optic of our laser systems, circles can be created at once, which speeds up the complete process drastically. You need a clean area to apply glue or insert a spot weld? A laser cleaner might be a very good solution for your problem! DEGREASINGDegreasing is mostly applied in the process & production industry.It can be initiated at the end of a process line as a final cleaning solution to remove any dirt, moist or other contaminants. In the end, you're left with a clean product, ready to be sold to the customer.     Another application is the preparation of a product for a subsequent process: glueing, welding, coating, etc.     How Does Laser Cleaning Work In 5 Steps Laser cleaning is an eco-friendly process used to remove rust, paint, oxide and other contaminants from metal surfaces. Because of its efficiency, it is being used in an increasing number of applications. Laser cleaning requires a pulsed fiber laser (typically  50 watts or more).     Traditional industrial cleaning methods are often seen as tedious (and for good reasons). Rust removal can be time and labor consuming. Oxide removal may involve hazardous chemicals specific to each material that needs to be removed. In some cases, paint removal by sandblasting can damage the metal underneath.     Dealing with these problems usually comes at a significant cost, but laser cleaning is changing this: it is a cost-effective solution that reduces cleaning times and maintenance.     If you are skeptical about these claims regarding laser technology, keep reading for the key facts about what a laser does when removing contaminants and coatings.     1. All Materials Have an Ablation Threshold     Laser ablation occurs when a material layer or a coating is removed with a laser beam. This is the process behind all laser cleaning applications. Take  laser rust removal  on steel. When the beam hits the surface, molecular bonds in the dust or rust layer are broken and ejected from the substrate. In less technical terms, you can imagine that the layer to be removed is simply vaporized by the laser beam.     A simple way to grasp the importance of the ablation threshold is to compare it to throwing a ball over a wall. If you don't throw it high enough, it will never make it over to the other side. Even if you throw the ball a thousand times, you will always fail. The same applies to laser derusting. You can shoot the laser beam a thousand times but as long as the energy is below the ablation threshold of the material you’re working with, nothing will ever be removed.     Now, every material has different properties and thus different molecular bonds. In other words, each material has a specific ablation threshold. To successfully remove a layer from a given material, the energy transferred by the laser beam must be above the ablation threshold of that particular material.     2. It is Possible to Remove a Material in a Highly Selective Way     Let's continue with our analogy. Imagine there was a second, higher wall behind the first one and that a ball was thrown with just enough energy to make it over the first wall, but not enough to make it over the second. The ball would bounce off the second wall and fall in between the two walls. Once again, no matter how many times you throw the ball, you will always get the same result. You will make it past the first wall but never the second.     Since there is an ablation threshold for each material, laser cleaning can discriminate between two or more materials when trying to remove an undesired layer from an object. Given a sufficiently large ablation threshold difference between the materials, it is possible to select a material to be removed (i.e., the one with the lower ablation threshold) while leaving the other material untouched.     For example, the rust ablation threshold is much lower than the threshold for common metals like steel and aluminum. The same goes for paint and oil. This vast gap between two values allows contaminants and coatings to be completely vaporized without any risk of damaging the base material underneath. There's just not enough energy for damage to happen.     3. A Strong and Short Power Burst Means Faster Removal     You can think of laser ablation as similar to carving stone with a hammer and a chisel. You can use a small hammer and do many small hits on your chisel. Or, you could just as well use a bigger hammer to leverage more power, hence reducing the required number of hits and increasing the removal speed. The idea is the same with laser cleaning, except that you only want to remove a layer of material: the contaminant.     Fiber laser cleaning systems  can remove any given layer using two different methods. Either the laser beam is a continuous wave of light, or it is pulsed at a given repetition rate. Even if the result is pretty much the same, the removal speed varies a lot according to the method.     Working Principle of Fiber Laser Cutting Machine     In today’s industrial manufacturing field,  CNC fiber laser cutting machines  have a wide range of applications in all walks of life due to their efficient and flexible processing advantages. Especially in metal processing,      fiber laser metal cutting machine  has almost become a must-have tool for all processing manufacturers, and People's daily life is closely related, but most people don't know how it works. Today, Mister Laser will take you to understand the working principle of  laser fibra cutting machine, so that everyone can understand it more deeply.                         The principle of laser cutting                 Laser cutting machine steel  is to focus the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, so as to achieve the purpose of cutting. The laser cutting process uses an invisible beam to replace the traditional mechanical knife. Its working principle also determines that it has advantages that other processing methods do not have:     (1) High precision, fast speed, narrow cutting seam, minimum heat-affected zone, the smooth cutting surface without burrs.     (2) The laser cutting head does not touch the surface of the material and does not scratch the surface of the workpiece.     (3) The slit is narrow, the local deformation of the workpiece is extremely small, and there is no mechanical deformation.     (4) It can cut steel, steel, carbon steel, stainless steel, aluminum alloy plate, and other hard materials without deformation.     (5) Numerical control programming can process any plan, can cut the whole board with a large format, no need to open the mold, economical, and time-saving.     What a Fiber Laser Marking Machine Can Do For You     If you are just entering into the world of marking, you are coming in at a very opportune time.     This is because this industry has old and new technologies that together make marking a very interesting, beautiful and profitable undertaking.     And none of the technologies are as flexible and intriguing as fiber laser marking.     In this article, we are going to introduction the technology of Fiber Laser marking Machine, understand its scientific background, its applications, materials targeted and its challenges.     After reading this article, you should be able to discern how best to use this machine for your own applications.     Understanding Fiber Laser Marking     A fiber laser machine essentially has three main parts, including the pump, the resonator and the beam delivery system.     The pump comprises of laser diodes from which a light beam is emitted and transmitted through fiber optics to a resonator which contains what is known as the gain medium.     The resonator hosts the gain medium, which in simple terms is a fiber optics medium doped with rare earth elements.     The main differences between different fiber laser applications are based on the wavelengths produced, which determines the surfaces that each type can mark on.     Metal markers are mainly Ytterbium doped, giving them the wavelength that is needed for optimal absorptivity for material marking various metals and plastics.     The resonator combines the gain medium with a set of full and semi-reflecting bragg grating components, that allow for refraction, amplification and filtering light waves to get the right wavelength required for marking.     The filtered beam is then transmitted to the beam delivery system, which is simply a beam expander and a lens contained in a beam head. This is the ‘laser pen’ that does the marking     Flexibility is the main advantage of fiber laser marking, thereby making it the most preferred engraving and marking technique in the industry, due to its versatility in marking diverse materials.     The information marked can also be chosen freely, ranging from text, numbers, logos, codes, images and photos.     Color change is a common process used in Laser Marking.     The process provides high contrast labelling on any material without damaging its surface.     In this process, the laser heats the material at the precise intended areas, exciting atoms and vaporizing the required parts, thereby providing a high quality contrast color-change on the material.     surface cleaning and structuring     Laser coating removal is an ablative process whereby laser energy is focused and absorbed by the surface, resulting in vaporization of the coating with minimal effect to the underlying substrate. This process can be applied to various materials including metal, plastics, composites and glass. Several new grades of press-hardened steels (PHS) have been developed for the body-in-white (BIW) structure in the automotive industry that combine desirable properties of strength and formability. Prior to assembling PHS components, the aluminum silicon coating must be removed to allow better weld surface capabilities. The  high power pulsed lasers successfully remove the coating without affecting the mechanical properties produced by the weld bond. Coating removal applications are also used in heavy industries such as aerospace and ship building for their cost-effective and environmental-friendly alternative to conventional abrasive and chemical processes. Because lasers operate as a non-contact surface removal application, there is no need for a secondary medium that contributes to waste streams.

Nonwoven fabrics are extensively used in    the manufacture of both single use (or disposable) and durable clothing, notable market segments being protective clothing, garment linings, interlinings, waddings, shoe linings and synthetic leather fabrics. Polyester Nonwoven: The High Strength, High Density NonwovenWhen it comes to demanding applications that require strong and durable fabrics, polyester nonwovens offer a great option. Nonwoven polyester fabric can be created from 100% polyester filament or polyester blend. Nonwoven polyester is an excellent choice for a wide range of application needs including industrial filter materials, medical and hygiene products, construction materials, telecom products, agricultural fabric, and more. A variety of fabric treatment options are available to endue polyester nonwoven materials with specific beneficial characteristics. These attributes may include: BiodegradableDry Cleaning ResistanceFlame RetardantHeat SealabilityHydrophilic Depending on the manufacturer, polyester nonwovens can be fabricated in custom colors and printing. Advantages of Buying Nonwoven Polyester Fabric from WPT Nonwovens WPT Nonwovens is your one stop source for nonwoven fabric, including polyester nonwoven. We manufacture and source spunbond, needlepunch, wetlaid and carded nonwovens from world class global and domestic suppliers.     Other advantages we offer include:     Virgin grade nonwoven polyester fabric     Ability to provide a sample within 30 days     Production and shipment of your order within four to six weeks     Extensive experience in developing nonwoven polyester fabric     Unsurpassed customer service     A fully capable manufacturing facility located in Beaver Dam, Kentucky     Types of non-woven     There are four main types of non-woven products: Spunbound/Spunlace, Airlaid, Drylaid and Wetlaid. This article covers these main types in detail.    The four main and most common types of-non-woven products are:     Spunbound/Spunlace.     Airlaid.     Drylaid.     Wetlaid.     SPUNBOUND/SPUNLACE     Spunbound fabrics are produced by depositing extruded, spun filaments onto a collection belt in a uniform random manner followed by bonding the fibres. The fibres are separated during the web laying process by air jets or electrostatic charges. The collecting service is usually perforated to prevent the air stream from deflecting and carrying the fibres in an uncontrolled manner. Bonding imparts strength and integrity to the web by applying heated rolls or hot needles to partially melt the polymer and fuse the fibres together. Since molecular orientation increases the melting point, fibres that are not highly drawn can be used as thermal binding fibres. Polyethelene or random ethylene-propylene copolymers are used as low melting bonding sites.     Spunbound products are employed in carpet backing, geotextiles, and disposable medical/hygiene products, automotive products, civil engineering and packaging products.     The process of Spunbound non-woven production tends to be more economical as the fabric production is combined with the fibre production.            AIRLAID     The process of airlaying is a non-woven web forming process that disperses into a fast moving stream and condenses them onto a moving screen by means of pressure or vacuum.     Airlaid fabrics is mainly composed of woodpulp and has a nature of absorbing well. It can be mixed with a definite proportion of SAP to improve its capabilities of absorbing wet. Airlaid non-woven is also referred to as dry paper non-woven. The nonwoven is made through the airlaying process. Transit the woodpulp into the bundle of airflow to make the fibres disperse and agglomeration on the floating web. Airlaid non-woven is reinforced of web.     Airlaid non-woven products are employed in a number of different products across a wide range of industry's including; the interlining of clothes, medical and hygiene products, embroidery material and filter material.     DRYLAID     Dry laid webs are mainly produced using staple fibres natural or manmade. Dry laid webs formation mainly consists of 4 steps: Staple fibre preparation –> Opening, cleaning, mixing & blending –> Carding –> Web laying.     Advantages of Drylaid non-woven production include; The isotropic structure of the web, voluminous webs can be produced and a wide variety of process able fibres such as natural, synthetic, glass, steel and carbon.     Drylaid non-woven products are employed by many products ranging from cosmetic wipes and baby diapers to beverage filtration products.     WETLAID     Wetlaid non-woven are non-wovens made by a modified papermaking process. That is, the fibres to be used are suspended in water. A major objective of wet laid nonwoven manufacturing is to produce structures with textile-fabric characteristics, primarily flexibility and strength, at speeds approaching those associate with papermaking.     Specialized paper machines are used to separate the water from the fibres to form a uniform sheet of material, which is then bonded and dried. In the roll good industry 5 -10% of nonwovens are made by using the wet laid technology.     Wetlaid is used for a wide ranging amount of industries and products. Some of the most common products that use wetlaying non-woven technology include; Tea bag paper, Face cloths, Shingling and Synthetic fibre paper.     How to wash polyester     Polyester explained: What it is and how to care for this fabric!Polyester fabric is one of the most synthetic materials used for clothing. However, you may be left wondering does polyester shrink or can you tumble dry polyester? Find out more about caring and washing polyester clothing.     What is polyester?    Polyester is a manufactured fibre made by combining a long-chain synthetic polymer with an ester from a substituted aromatic carboxylic acid.

Langkj?r, of the Saxo Institute, University of Copenhagen is a historian specialized in fashion and costume history.     Sport is an important part of many people’s lives—as both recreation and entertainment. It is also a sizeable industry with political and economic ramifications in today’s world. Within the last half-century or so, sportswear has become a driving force for new trends in fashion and for textile innovation. This special issue of    Fashion Practice    was inspired by the “Spandex to Sportstech—Fashion and Innovation in Sportswear” conference, organized in 2011 by guest editor Mette Bielefeldt Bruun at the Danish National Research Foundation’s Centre for Textile Research at the University of Copenhagen.     The stated purpose of    Fashion Practice    is to provide a site for multidisciplinary treatments of the practices of fashion. “Spandex to Sportstech” was designed as a cross-disciplinary forum for renewed consideration of functional, social, aesthetic and environmental issues connected with sportswear, and some of the papers presented here are rooted in original conference contributions. This journal issue is truly cross-disciplinary, beginning with fashion history, represented by Michael A. Langkj?r with “Urban Fitness, Gendered Practices, and Fine Art: The Significance of Antonio Lopez’s Sporty Styling of Fashion” and moving on to the sportswear industry itself with its brands and markets, represented by Kristine Holm-Jensen with “Specialized in Sportswear: Transformations of the Generic Knitwear Industry in Post-War Denmark.” Several articles then consider fiber and textile technologies and their design applications. Jane McCann leads this group with her “Sportswear Design for the Active Ageing.” McCann is followed by Deborah A. Christel and Nicole H. O’Donnell with “Assessment of Women’s Plus-Size Swimwear for Industry Applications.” Alicia Potuck, Sarah Meyers, Ariana Levitt, Erik Beaudette, Hong Xiao, C. C. Chu, and Huiju Park complete the group with their “Development of Thermochromic Pigment Based Sportswear for Detection of Physical Exhaustion.” In “What’s the Problem? Odor-control and the Smell of Sweat in Sportswear,” Ingun Grimstad Klepp, Madeline Buck, Kirsi Laitala and Marit Kjeldsberg look at how fiber technologies connect with our social values associated with body odor and its suppression; in doing so, Klepp et al. also mention the issue of sustainability. A forthright appraisal of the problem of sustainability within the sportswear industry is given by an industry representative to Lena Erdnü? in “A Perspective on Sustainability Initiatives of a Swedish Outdoor Brand: An Interview with Lennart Ekberg from Hagl?fs.” Finally, Lauren Downing Peters has contributed a review of the Museum of the City of New York’s 2013 exhibition: “Stephen Burrows: When Fashion Danced.”     Difference between Sweatshirt and Hoodie     What is the difference between sweatshirt and hoodie? Both are sportswear garments to keep you warm in the cold weather. Read to know the exact difference between a sweatshirt and a hoodie.     There is nothing superior to a classic sweatshirt or a hoodie when it comes to fashion to beat the winter chills. Just like denim jeans and t-shirt, a sweatshirt or a hoodie makes up an essential part of any individual’s wardrobe, specifically the teenagers who want to keep it stylish yet cozy. Both sweatshirts and hoodies are trending these days and are a style statement with a range of patterns.     Sweatshirt and hoodies are sportswear garments to keep you warm in the cold weather. They have quite a similar look at a glance and often are made with similar fabrics; however, there is a difference between sweatshirt and hoodie. Very obvious is that a hoodie has its hood while a sweatshirt is without a hood. The sporty garment is worn by all ages and genders. Several brands, including UNIQLO, offer a diverse collection of both sweatshirts and hoodies with comfortable material, sizes, and various colours. Durable and versatile, a wide variety will let you feel the warmth in winter with a stride.     The Best Men's Tracksuits Are the Next Great Frontier in WFH Style     There’s something about the best men's tracksuits, comfortable as they may be, that just feels more purposeful than a sweatsuit. The fabric is denser and more structured, and there’s a jacket involved—one that you have to go to the trouble of putting on and zipping up, rather than just slipping over your head like a hoodie. And then there are all the baked-in associations. Tracksuits are uniforms for people who get shit done efficiently and ruthlessly: elite athletes, UK grime rappers, mall-walking senior citizens determined to stay in shape, tough guys stretching from the Russian section of Brighton Beach all the way to actual Russia. Oh, yeah, and they also look really, really dope—leisurely and relaxed, but still plenty smart and distinctive. Tracksuits are so essential right now that literally every brand on the planet makes their own swishy, striking take. That might sound like a good thing, only the actual number of available options is so vast that it’s honestly sort of anxiety-inducing—and lord knows you don’t need any more of that at the moment. So we did you a solid and surveyed hundreds of versions, from the tiniest underground streetwear labels to the oldest luxury fashion houses to the biggest athletic conglomerates, and narrowed it down to these: the 21 best men's tracksuits in 2021. Pick the one that’s right for you, get into it pronto, and give your tried-and-true sweats a well-earned break.

描述: Types of Shovels: Comprehensive Guide While buying tools for your toolkit, garage, or workshop, you can find yourself across a wide range of hand tools. As you would expect, these tools are made for all kinds of usage depending on the buyers. Although, a few hand tools are highly universal that can be used for a wide range of applications making them a must-have for any toolkit.One such hand tool that you will find in almost any garage is a shovel. Whether you are working around your home or at a job site, there are a lot of cases where you might need a shovel. Although, even while buying a shovel, you can find a lot of different types, which can be quite confusing for a lot of buyers. In that case, make sure to check all the different types of shovels stated down below to easily pick the best one for you:     Now that you know that shovels are highly versatile in general, this means that they get used for a wide range of applications. And while you can use any normal shovel for multiple things, you will not get the best results. Instead, you should go through the following different types of shovels and pick the one made for your specific use case for the best results:     1. Digging Shovel     Whenever you are talking about shovels in general, a digging shovel is most likely what comes to your mind. As per the name, such a shovel is used for digging up soil for gardening and other applications. To offer high functionality, these shovels have a decently sharp blade for easily cutting through soil and other things present in the ground. You will also find a high grip collar handle with most digging shovels for easily moving hardened soil if needed. But even if you are going with a digging shovel, you will the following three types of blade options to choose from:     A) Square Digging Shovel     SQUARE DIGGER     As per the name, a square digging shovel has a flat and straight blade end which makes it useful for edging and making trenches. You can also use a square digging shovel to move shrubs and bushes if needed. Since the blade is completely straight and rigid, it can be a great option for digging up hardened soil.     B) Pointed Digging Shovel     Round Point Shovel     With a pointed digging shovel, you can work in tight spaces as well as in a part of soil that has a lot of roots and rocks. Because the blade is curved at the front, you can also scoop up loose soil with ease in comparison to a square digging shovel.     C) Round Digging Shovel     ROUND DIGGER shovel     A round digging shovel has a completely dome-shaped blade at the end, which is generally used for gardening. If you want to move small plants, shrubs, and flowers, then this can be a great option as the round blade does not cut the roots. Similar to a pointed digging shovel, a round digging shovel is also ideal for loose soil and not hardened soil.     . Edging Shovel     Edging Shovel     As per the name, an edging shovel is made for highly specific usage. To be exact, you will have to use an edging shovel when you wish to create edges in the soil. This is generally ideal for gardens where you might want to distribute the solid of your garden into different parts for different plants and flowers. In comparison to most other shovels, an edging shovel has a very unique-looking blade which is similar to a half-moon. Since this type of shovel uses a very thin blade, you can easily use them alongside fences, sidewalks, garden borders, driveways, and other places where you have to create a precise edge.        3. Trench Shovel     Trench Shovel     You can also go with a trench shovel if you are looking for highly specialized shovels to be used in your garden or backyard. Just per the name, a trench shovel is used for making trenches in any given area. To make sure that your trenches are deep and straight at all times, a trench shovel uses a long and narrow blade. This blade has a sharp pointed end along with a concave design resulting in almost a triangle-shaped blade. The angled design of a trench shovel allows it to quickly move a lot of soil for quickly, making trenches wherever you need.     How To Use A Round Head Shovel In The Garden     Gardeners know that the right tool, used in the right way, can ensure success on every task. We treasure our tools like a chef treasures his/her knives. Round point shovel uses extend past digging to scooping and are useful in transplanting, trenching, moving compost or mulch and many more applications. Taking care of the tool will extend its life when its edges are kept sharp and the shovel clean and dry. Rounded shovels usually have a beveled edge to help penetrate tough soil situations. They may also have a point to push into soil. The edges are curved to facilitate scooping. Handles are the height at which most people stand and can be ergonomically angled. Grips are often cushioned to prevent blisters. These specialized tools are widely available at any big box store or garden center. It is important to choose one which will last. Wooden handled tools often break on big jobs. The attachment of the scoop to the handle should be welded securely. Since it is one of the most popular tools, using round point shovels for many tasks makes it a work horse of the garden. Good construction and sturdy fabrication will make these tasks a little lighter. What is a Round Point Shovel Used For? Rounded shovels are a bit like a Ginsu knife. They may not slice, dice and julienne, but they can cut, dig, scoop, lift and chop through hard soil. These are invaluable tools for any gardener. Taking care of the tool is essential to its long life. Always rinse the shovel and allow it to air dry before putting it away. This prevents rust that will destroy the metal over time. Every spring, bring out the shovel and use a whetstone or hand held file to sharpen the edge. That will make breaking through tough soil much easier. Keep handles dry if they’re wooden, and occasionally sand them to remove any splinters. Rub with linseed oil to protect the wood.     Choosing Shovels For Gardens: What Shovel Do You Need For Gardening     The sheer variety of shovels available in gardening and hardware stores can be confusing. Fortunately, most garden shovels fall into a few common categories, each intended to be used for specific garden tasks. If you’ve ever wondered “what shovel do you need for gardening,” this article will help answer your question. Before learning about the common types of garden shovels, it is helpful to know the parts of a shovel. From top to bottom, you will find the grip, then the handle, which varies in length, with longer handles better suited to digging deep holes and shorter handles better suited to precise tasks. Next is the collar, where the blade is fastened to the handle. At the bottom is the blade, typically made of metal or, in some cases, plastic. The flat portion at the top of the blade is called the step. The step allows you to use your foot and body weight to push the shovel into the soil, which is much easier than using just your arms! The blade and tip, also called the point, come in different shapes depending on the type of shovel.     A brief history of the pick axe     Pre-history     Ancient Persian Susa pick axe    The pickaxe is thought to be one of the oldest tools used by mankind. Its use can be traced back to prehistoric civilizations, and has been associated with everything from cultivation of land to mining and war over the centuries.     Ancient history     Ancient Elam city of Susa being taken by Assyrian soldiers    The relief opposite shows Assyrian soldiers taking the ancient Elam city of Susa (2700-539BC) and depicts them using pickaxes and crowbars to destroy and loot the city.     Middle age warfare     Polish winged hussars horsemans pickaxe    The horseman's pickaxe was often called a war hammer and was a weapon used through the Middle Ages across Europe by cavalry in war.     The main use of the horseman's pickaxe during battle was to tear cavalry from their mounts.     Another one of its uses was as a means to pierce thick armour or mail that a standard sword was unable to penetrate.     Middle age war hammer    However, the horseman's pickaxe has several drawbacks as a weapon. Its heavy weight made it unwieldy and easily avoided by the enemy.     Injuries caused by the horseman's pickaxe were small and rarely fatal, and if swung with too much force, the weapon could become stuck in the victim or their armour, and be difficult to retrieve.     19th Century railroad construction     Railroad construction with the use of a pickaxe    Railroad pickaxes are the most common type used today. They get their name from their use in constructing The Great American Railroad between 1850 and 1890, which connected the rest of America to the once wild west.     Mining     Pickaxe being used in a coal mine    A mandrill, also referred to as a miner's pickaxe is used in traditional mining, or old-school mining, as it is a mining method involving the use of basic manual tools, like pickaxes.     This type of mining was employed throughout the world up to the early 1900s. It is still a mining method employed in some countries today, such as Colombia, Peru and parts of Africa.     Tips For Using a Machete     Cutting and trimming with hedge shears will help keep exuberant growth under control, but sometimes you need a tool with more heft and more bite — a machete. Backyard swashbucklers, take up your blades: with a machete (sometimes called a cutlass), you're not just taming the blackberries, you're wielding a tool with traditions.     A machete is a powerful tool for clearing brush.    In the tropics, machetes are ubiquitous, all-purpose tools: they have been used to carve trails through tropical forests, to slash out clearings for crops, to crack open coconuts and slice papayas, and, of course, as imposing weapons. Use your machete to keep the peace with weeds and brush in your garden, or to serve watermelon with a flourish. Use it with care and respect: it is a razor-sharp tool. When you use it: Dress for the job, in sturdy shoes, long pants, and work gloves.Cut in front of yourself. Take big swings, leading with your elbow, so the blade meets the stems and stalks at an angle and slices through them. Never reach out to one side or the other to make quick clean-up cuts in such a way that the blade is moving toward your legs.     Keep your free hand well out of the way. Never grab a fistful of brush with one hand and swing the machete with the other; some users recommend holding a stout forked stick in your free hand for this purpose.
