stamping parts

Stamping is a forming method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain workpieces (stampings) 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.Stamping is a forming method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain workpieces (stampings) of the required shape and size.
