Metal 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, cutting, parting, blanking, piercing, trimming, notching, lancing, half-blanking ,shaving, fine blanking embossing, ribbing , bulging ,louvering , hole flanging, deeping , sizing, marking ,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.
