Stamping is a method of forming and processing workpieces (stamping parts) of required shape and size by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity.
