  [url=http://www.jinmaifastener.com/metal-stamping-parts/]Metal stamping [/url]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 Stamping

    Metal 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 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[url=http://www.jinmaifastener.com/electric-power-fittings/] fittings[/url] 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?    

    (1)            Easy to Connecting Conduit & Running Wire

    If 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.
