The metal stamping process begins with a flat metal sheet, typically made of steel, aluminum, or brass. The initial step involves feeding the metal sheet into a stamping press where it is shaped using a combination of dies and punches. The dies are designed to create specific shapes, while the punches apply force to cut or deform the metal. Depending on the complexity and volume of the parts required, metal stamping can be performed using various techniques, including progressive stamping, deep drawing, and strain gauge stamping.
