Metal stamping
——————————————————————————
Metal 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 operating where every stroke of the press produce the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on the sheet metal, but can also be used on other materials, such as polystyrene.
