Traditional die-cutting is a cutting process of post-processing of printed matter. Die-cutting technology can make printed matter or other paper products into die-cutting knives according to pre-designed patterns for cutting, so that the shape of printed matter is no longer limited to straight edges and right angles. Traditional die-cutting tools are combined into die-cutting plates according to the patterns required by product design, and under the action of pressure, printed matter or other plate-like blanks are rolled into the required shapes or cuts. Indentation technology is to press the line marks on the plate with a line knife or a line die under the action of pressure, or to roll the line marks on the plate with a line roller, so that the plate can be bent and formed at a predetermined position. Usually, the die-cutting and indentation process is a process of combining the die-cutting knife and the line pressing knife in the same template, and simultaneously performing die-cutting and indentation processing on the die-cutting machine, which is referred to as die-pressing.

Stamping is a production technology that makes the sheet material directly subjected to deformation force in the die with the help of the power of conventional or special stamping equipment, so as to obtain product parts with certain shape, size and performance. Sheet metal, die and equipment are the three elements of stamping. According to the processing temperature of hot stamping, it can be divided into hot stamping and cold stamping. The former is suitable for plate processing with high deformation resistance and poor plasticity; The latter is carried out at room temperature and is a common stamping method for thin plates. It is one of the main methods of metal plastic working (or pressure working) and also belongs to material forming engineering technology.

The die used for stamping is called stamping die, or stamping die for short. Stamping die is a special tool for batch processing materials (metal or nonmetal) into required stamping parts. Stamping die is very important in stamping. Without the required stamping die, it is difficult to carry out mass stamping production. Without advanced stamping die, advanced stamping technology cannot be realized. Stamping technology, die, stamping equipment and stamping materials constitute the three major elements of stamping processing, and only by combining them can stamping parts be obtained.
