Metal stamping is a process that uses punch and die to deform or fracture iron, aluminum, copper and other plates and heterosexual materials to achieve a certain shape and size.

Metal stamping is sometimes called sheet metal forming, but it is slightly different. The so-called plate forming refers to the use of plates, thin-walled tubes and thin profiles as raw materials. The forming method of plastic processing is collectively referred to as plate forming. At this time, the deformation in the direction of thick plate is generally not considered.

Stamping process can be roughly divided into two categories: separation process and forming process (also divided into bending, deep drawing and forming). The separation process is to separate the stamping part from the blank along a certain contour line in the stamping process, and the quality of the separation section of the stamping part should also meet certain requirements; The forming process is to make the stamping blank plastic deformation without damage and transform it into the required finished shape.
