The stamping part is a production technology of a product part which is deformed by a deformation force in a mold by means of power of a conventional or special stamping apparatus, thereby obtaining a shape, a size and a performance. Sheets, molds and equipment are the three elements of stamping. Stamping is a method of cold deformation of metal. Therefore, it is called cold stamping or sheet stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing) and is also part of material forming engineering technology.
