Stamping

 Stamping parts are formed by applying external force to plates, strips, pipes and profiles by means of presses and dies to produce plastic deformation or separation, so as to obtain workpieces (stamping parts) of the required shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks to be stamped are mainly hot-rolled and cold-rolled steel plates and strips.
