Stamping process can be divided into four basic processes:
Blanking: the stamping process (including punching, blanking, trimming, sectioning, etc.) to separate sheets.
Bending: the stamping process of bending the sheet into a certain angle and shape along the bending curve.
Deep drawing: a stamping process in which flat sheet metal is transformed into various open hollow parts or the shape and size of hollow parts are further changed.
Local forming: the stamping process (including flanging, bulging, leveling, and shaping) in which various local deformations of different properties are used to change the shape of blank or stamping parts.
