    1, stamping by press and die plate, strip, pipe and profiles, such as outside force, to produce plastic deformation or separation, to obtain the required shape and size of the workpiece forming method (stamping). Stamping and forging are the same plastic processing (or pressure processing). The blanks are mainly hot rolled and cold rolled steel and steel strip. Of all the steel in the world, 60 ~ 70% are plates, most of which are processed into finished products. Automobile body, chassis, fuel tank, radiator, boiler drum, container shell, motor, electrical core silicon steel sheet and so on are stamping processing. Instruments, household appliances, bicycles, office machinery, life utensils and other products, also a large number of stamping parts.
 
    Stamping processing is the use of conventional or special equipment of the power, the deformation of sheet metal in the mould is directly force and deformation, thereby gaining a certain shape, size and performance of the production technology of product parts. Sheet, mould and equipment are three elements of stamping. The stamping processing temperature is divided into hot stamping and cold stamping. The former is suitable for the plate processing with high deformation resistance and poor plasticity. The latter is done at room temperature, and is a commonly used method of stamping. It is one of the main methods of metal plastic processing (or pressure processing) and also belongs to material forming engineering technology.
 
    The die used in stamping is called stamping die. The punch is a special tool for batch processing of materials (metal or non-metal) into the required blanks. The punching die is very important in stamping, and it is difficult to carry out the batch stamping without the stamping die. Without advanced punching die, advanced stamping process cannot be achieved. Stamping process and die, stamping equipment and stamping materials constitute three elements of stamping process, only they can be combined to get the stamping parts.
 
    2. Punch press is a press press. In the national production, the stamping process of than traditional mechanical processing for material and energy saving, high efficiency, technical requirements for operators is not high and through a variety of mold application can make machining these advantages, the products cannot be achieved by thus its use more and more widely.
 
    Stamping production is mainly aimed at the plate. Through the mold, can make blanking, punching, forming, drawing deep, finishing, finishing, shaping, riveting and extrusion, etc., widely used in various fields. If we use the switch socket, the cup, the cupboard, the saucer, the computer case, even the missile plane... There are a lot of accessories that can be produced using punch presses.
