The stamping process is a metal processing method, which is based on the plastic deformation of metal. It uses molds and stamping equipment to apply pressure to the sheet to cause plastic deformation or separation of the sheet to obtain a certain shape, size and performance. Parts (stamped parts). Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger batches of parts, which is easy to realize mechanization and automation, and has higher production efficiency. At the same time, stamping production can not only strive to achieve less waste and no waste production, but also has margins in some cases. The leftover material can also be fully utilized.
