Stamping parts are mainly formed by stamping metal or non-metal sheet materials with the help of the pressure of the press through the stamping die. It mainly has the following characteristics:

⑴ Stamping parts are made by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity. After the sheet is plastically deformed, the internal structure of the metal is improved, which improves the strength of the stamping parts. .

(2) Stamping parts have high dimensional accuracy, and are uniform in size with the mold parts, and have good interchangeability. No further machining is required to meet general assembly and use requirements.

(3) During the stamping process, since the surface of the material is not damaged, it has a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments. Stamping is a production technology of product parts with a certain shape, size and performance, by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force in the mold and deformed. Sheet material, mold and equipment are the three elements of stamping processing. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet stamping, or stamping for short. It is one of the main methods of metal plastic working (or press working), and also belongs to material forming engineering technology.

Of the steel in the world, 50-60% are made of sheets, most of which are finished products that have been pressed. Car body, radiator fins, steam drums of boilers, shells of containers, iron core silicon steel sheets of motors and electrical appliances, etc. are all stamped and processed. There are also a large number of stamping parts in instruments, household appliances, office machines, storage utensils and other products. Stamping is an efficient production method, using composite molds, especially multi-station progressive molds, which can complete multiple stamping technical operations on one press to complete the automatic generation of materials. The production speed is fast, the rest time is long, the production cost is low, and the collective can produce hundreds of pieces per minute, which is favored by many processing plants.

Stamping parts are more powerful than castings and forgings, and have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, ribs, coils or flanges that are difficult to manufacture in this skilled diameter to improve their rigidity.
