Stamping is a forming process that relies on presses and molds to apply external forces to plates, strips, tubes, profiles, etc., to produce plastic deformation or separation, so as to obtain workpieces of the desired shape and size (stamped parts). Compared with castings and forgings, stamped parts are thin, uniform, light and strong. Stamping can produce workpieces with reinforcements, ribs, undulations or flanges that are difficult to manufacture by other methods in order to improve their rigidity.

Stamping sheet metal forming; stamping the use of molds in the press sheet metal into a variety of sheet parts and shells, containers, or pipe fittings into a variety of tubular workpieces. This type of molding process in the cold state is called cold stamping, referred to as stamping.

Stamping is the power of conventional or special stamping equipment, so that the sheet in the mold is directly subject to deformation force and deformation, so as to obtain a certain shape, size and performance of the product parts of the production technology. Sheet, mold and equipment is the three elements of stamping. According to the stamping processing temperature is divided into hot stamping and cold stamping. The former is suitable for high deformation resistance, poor plasticity of the sheet processing; the latter is carried out at room temperature, is commonly used in thin plate stamping method. It is one of the main methods of metal plasticity processing (or pressure processing), and also belongs to the material molding engineering technology.

The mold used for stamping is called a stamping die, or die for short. The die is a special tool for batch processing of materials (metallic or non-metallic) into the required punched parts. Stamping die in stamping is crucial, no meet the requirements of the stamping die, batch stamping production is difficult to carry out; no advanced stamping die, advanced stamping process can not be realized. Stamping process and mold, stamping equipment and stamping materials constitute the three elements of stamping processing, only they are combined with each other in order to come up with stamped parts.
