Stamping is a forming processing method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the required shape and size. Stamping forming is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation forces and deform in the mold, thereby obtaining product parts of a certain shape, size and performance.
Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a metal cold deformation processing method, so it is called cold stamping or sheet metal stamping, referred to as stamping. It is one of the main methods of metal plastic processing.
