What is Stamping?

Stamping is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining.This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene.

Sheet Metal Stamping Process

There are basically only three components to sheet metal stamping—the sheet metal, die, and press machine—but any single part can require multiple steps to arrive at its final form. The following guide explains common processes that might occur during metal stamping.
