Stamping processing is the use of conventional or special stamping equipment power, metal progressive die so that the plate in the mold directly under the deformation force and deformation, so as to obtain a certain shape, size and performance of the product parts production technology.Plate, progressive die structure and equipment are the three elements of stamping processing.Stamping is a kind of metal cold deformation processing method.Therefore, it is called cold stamping or sheet metal stamping, or simply 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, die for short.Die is the material (metal or non-metal) batch processing into the required punching tools.Punching die is very important in stamping, without the required punching die, batch stamping production is difficult to carry out;Without advanced die, advanced stamping process can not be achieved.Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing, only they can be combined to get stamping parts.
