Stamping is a kind of production technology that uses the power of conventional or special stamping equipment to directly deform the sheet metal in the die, so as to obtain a certain shape, size and performance of product parts. Sheet metal, die and equipment are the three elements of stamping process. Stamping is a method of metal cold deformation. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology.

Stamping equipment manufacturers, stamping used by the die known as stamping die, referred to as stamping die. Stamping die is a special tool for batch processing materials (metal or non-metal) into required stamping parts. The stamping die is very important in stamping. Without the required stamping die, the mass stamping production is difficult to carry out; without the advanced stamping die, the advanced stamping process cannot be realized.

Stamping technology and die, stamping equipment and stamping materials constitute the three elements of stamping processing. According to the analysis of stamping automation company, only when they are combined with each other can stamping parts be obtained.

The kind of long strip is still cold stamping, but the stamping die is different. The one with continuous material feeding is called continuous die. The one with single product put in for processing is called single die. The one with material one by one put in for punching is called compound die.
