Stamping is a sheet metal forming process. The sheet metal is placed in a mold and shaped with a punch. When the part to be created is deeper than its diameter (at least twice the diameter), the process is called "deep" drawing. When the depth of the part to be built is less than 0.3 diameter, the process is called "shallow" drawing. A flat sheet of metal will be placed on the positioning ring of the mould. The punch presses the copper sheet into the die, creating a shape that approximates the die. Stretching special tools (die, punch, etc.) on the punching machine will generate the load or kinetic energy required to restrain the raw material during the punching process. During stamping of low-alloy sheets, the raw material is transformed into the shape of the die. This type of
forming is regulated by increasing the pressure on the workpiece and releasing a lubricating fluid (deep drawing oil) in the workpiece or mold.
