NdFeb Magnets

Known as third generation of Rare Earth magnets, Neodymium Iron Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnet today. Since they are made from Neodymium, one of the most plentiful rare earth elements, and inexpensive iron, NdFeB magnets offer the best value in cost and performance.

Applications of NdFeB magnets are: magnetic separators, linear actuators, microphone assemblies, servo motors, DC motors (automotive starters), computer rigid disc drives, printers and speakers. 

NdFeB Magnets

Neodymium Magnets are made from compound containing the elements of Neodymium, Iron and Boron (NdFeB). The NdFeB magnets are the strongest type of magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.

The NdFeB magnets are anisotropic sintered magnets-- the compound is jet milled to a fine powder and is then compacted in the presence of a magnetic field to give it a preferred direction of magnetisation (making it anisotropic in performance). The NdFeB magnets are then sintered to fuse the powder together before final machining and magnetising produces the completed super strength Neodymium magnet.

The Neodymium magnets are also known as Neo magnets, Neodymium Iron Boron magnets, Neodymium-Iron-Boron magnets, NdBFe magnets, NdFeB magnets, NIB magnets, Super Strength magnets and Rare Earth magnets (please note that SmCo is also called a Rare Earth magnet). NdFeB is called a Rare Earth magnet because the Neodymium is a Rare Earth element, having a value of 60 on the Periodic Table. For note, there is nothing rare about Rare Earth magnets – the required elements are readily available and the NdFeB magnets are produced in several hundreds of tonnes each year.

Magnetic Fields

Magnet is a material that provides magnetic field. A magnetic field is invisible, however, responsible for most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.

A permanent magnet is an object made from the material that is magnetized and creats its own persistent magnetic field. An every day example is a refrigerator magnet used to hold notes on the door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic. These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.

 

Ferromagnetic materials can be divided into magnetically “soft” materials like annealed iron, which can be magnetized but do not tend to stay magnetized, and magnetically hard materials, which do. Permanent magnets are made from “hard” ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a powerful magnetic field during manufacture, to align their internal microcrystalline structure, making them very hard to demagnetize. To demagnetize a saturated magnet, a certain magnetic field must be applied, and this threshold depends on cercivity of the respective material. “Hard” materials have high coercivity, whereas “soft” materials have low coercivity

 

The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces. The local strength of magnetism in material is measured by its magnetization.

What is the Applications and Uses of Steel Pipe Flanges

       Stainless pipes and tubes are a great option in compared to metal ones. In recent times, there has been significant rise in their use. They are used to carry out various functions. The durability and economy are some of the many reasons for the popularity and uses of steel pipes and tubes. Steel pipes and tubes are preferred in many industries. The automotive and piping industry has been using them in various applications. Steel pipes and tubes are extremely light in weight and high rigidity. Steel pipe flanges are widely used all around the world in many industries. Pipe flanges are mostly used in piping and tubing systems.

       In piping and tubing systems, the steel pipe flange plays a very important role. It is preferred by the people in the industry as it offers great solutions. This product has been developed to produce high quality components that are durable from corrosion. This is the precise reason for the companies dealing in piping opting for flanges. The industry has been given a tremendous advantage with the use of pipe flanges. Buying these products from reputable manufacturing company will offer a better solution.

The Function and Types of Shear Machine

       There are many types of shears used to shear sheet metal. Shearing, also known as die cutting, is a process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. The most commonly sheared materials for shear machine are in the form of sheet metal or plates, however rods can also be sheared. Shearing-type operations include: blanking, piercing, roll slitting, and trimming. It is used in metalworking and also with paper and plastics. Following I will introduce 6 different types of shear.

1. 

   Alligator shear
   Alligator Shear: It is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears, however there are types for excavators.
2. Bench Shear: It is usually used for cutting rough shapes out of medium sized pieces of sheet metal, but cannot do delicate work. For the small shear, it mostly designed for a wide field of applications. Light weight and easy efficient operation, yet very sturdy in construction.
3. Guillotine: This type of shear can be called a squaring shear, power
   shear, too. This machine may be foot powered (or less commonly hand powered), or mechanically powered. It works by first clamping the material with a ram. A moving blade then comes down across a fixed blade to shear the material.

4. Power shears: A power shear is electrically or pneumatically powered hand tool designed to blank large pieces of sheet metal. They are designed to cut straight lines and relatively large radius curves. They are advantageous over a bandsaw because there is not a size limit.
5. Throatless shear: It is a cutting tool used to make complex straight and curved cuts in sheet metal.
6. Tin snips: Snips are hand tools used to cut sheet metal and other tough webs. Tin snips are one of the most popular type of snips. Depending on the size of the blade, tin snips can cut between 23 and 16 gauge cold rolled low-carbon steel.

The Types of Coil Spring and Its Suppliers

       A coil spring, also known as a helical spring, is a mechanical device, which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. As a special type of torsion spring, the material of the spring acts in torsion when the spring is compressed or extended. Metal coil springs are made by winding a wire around a shaped former - a cylinder is used to form cylindrical coil springs.

       There are two main purposes for using a helical spring. The first is to reduce shock by absorbing it into the springs, such as with a sofa or bed mattress. The springs help support the fabric and padding by more evenly distributing weight across the surface and by taking some of the strain off the other materials. Springs are generally made of heavy grade metal for this purpose and are generally larger and bulkier when used in mattresses and other surfaces which must hold a lot of weight. The use of coil springs is also common in the automotive industries. These often need replacement regularly and are used in a variety of parts. Springs can become corroded over time. Other items which may contain coil springs include power tools, mechanical pencils, retractable pens, toys, and construction materials.

       In the coil spring market, one of the main areas supplying is China. Among the various China spring suppliers, it’s not easy to choose the one who is really trustworthy. First of all, you need to clarify what kind of spring is what you want. Then you can delete some unrelated suppliers. Furthermore, you may have to do detail research on each supplier’s background, whether its factory is certificated by ISO is one of the crucial consideration points. You can find reviews and discussion on related industry forums or association website. Once you make sure all the detail information about your target supplier, you can send your inquiries to them and make comparison about the quotations. In short, it’s better for you to be cautious! 

The Metalworking Process about Plate Bending Machine

       A plate bending machine is used for forming metals like steel plate, carbon steel plate, stainless plate forming, under the force of 3 or 4 rolls together processing, the final cylinder, roll formed. This machine consists of 3 roll plate bending machines and 4 roll plate bending machines. 3 roll plate bending machine usually are used for heavy duty plate forming, while 4 roll plate bending machines are mainly use in the light plate forming.

       Plate bending machine is like a roll bender, which is a mechanical jig having three rollers used to form a metal bar into a circular arc. The rollers freely rotate about three parallel axes, which are arranged with uniform horizontal spacing. The two outer rollers have the same fixed vertical height and make contact with the underside of the bar to be formed. The middle roller has an adjustable height and makes contact with the topside of the bar.

       The bar to be shaped is assumed to have a uniform cross-section, but not necessarily rectangular, as long as there are no overhanging contours, i.e. positive draft. Such bars are often formed by extrusion. The bar is suspended between the rollers. The end rollers support the bottom-side of the bar and have a matching contour (inverse shape) to it so as to maintain the cross-sectional shape. Likewise, the middle roller is forced against the topside of the bar and has a matching contour to it.

       This kind of metalworking process is called bending. It can produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.

What is Flexible Metal Conduit?

       The metal conduits can be used in a wide scope of applications including lamps, communications, air conditioning systems, and fire alarm systems. The items can provide safety to work space and construction facilities with vibration-proof and anti-interference. Flexible conduit can also solve the problems found within wiring and pipeline constructions.

       A flexible metal conduit is a variety of piping used to hold electrical wires and similar cabling. This style of conduit is common in areas where the strength of metal is required, but the conduit still needs flexibility. This kind of flexible conduit bends to accommodate their environment, but does not permanently take on any specific shape. Depending on its overall design and purpose, the flexible metal conduit may be waterproof, or it may have gaps.

       The most common places to see any form of flexible metal conduit include public structures and manufacturing locations. Private homes and businesses are less likely to use metallic conduits, and when they do, it is typically inside a wall. Public areas, particularly those made primarily of steel and concrete, use flexible metal conduits to protect interior systems and prevent unintentional damage or vandalism. Manufacturing areas use these systems to accommodate machinery movement and maintenance.

Industrial Shelving Helps you on Saving and Managing Space

       Recent design systems used for manufacturing industrial shelving or stackable racks have made them trendy and popular. Over the years, their demand has risen for industrial, residential, institutional, commercial and agricultural purposes for saving and managing space. When it comes to purchasing metal shelves, there are a number of things that you should consider. You need to determine precisely what you require. It is crucial for you to plan and carefully examine the spaces where the shelves are going to be installed. Some of these areas include the pantry, garage, store or warehouse. The shelves provide a solution for organizing these spaces in a systematic way.

       Different materials can be used for industrial shelving. They include metal, wood, plastic, fiber glass, or a combination of more than one of these materials. The factors that you should consider are lifespan, durability, cost, safety and stability. In addition to that, you should also take into account other aspects such as size, beauty, height, ease of access and mobility. All these factors count when buyers are purchasing these metal shelves.

       Metal shelves that have a capacity of 150-1000 pounds per shelf are gaining increasing popularity nowadays. They can be made from such materials as aluminum, stainless, chrome plated or galvanized steel. A common example of industrial shelving is the wire racking system. Its main purpose is in retail, general storage and the food service.

Selective Pallet Racking Has Become the Most Common Pallet Racking System Today!

       Pallet racking is a material handling storage aid system designed to store materials on pallets. Even though there are many varieties of pallet racking, all types allow for the storage of palletized materials in horizontal rows with multiple levels. Among the various types, selective pallet rack system is one of the most popular one. It provides easy accessibility to all products. A selective pallet rack system is often used in a “big-box” distribution application, or in retail store inventory rooms, cold storage applications, wholesale stores, etc.

       And wire decking is one of the important components of selective rack. It is widely used as a safety measure on selective pallet rack to prevent pallets or the products stored on them from falling through the rack structure. Wire mesh decking comes in various thicknesses and mesh dimensions. This construction also allows for easy identification of shelf contents and prevents dirt and other debris from accumulating on the shelves because of the holes in the mesh. Most wire decking has U-shaped channel supports, also known as struts, to support the load. Some types of decking are manufactured with solid metal instead of wire mesh. Even though the solid decking provides a greater distributed weight capacity, it is discouraged by fire inspectors because sprinkler systems cannot spray through the shelves to levels below.

       All types of pallet racking create some level of increase storage density with the least dense being the least expensive and cost increasing with storage density.
