The process starts with the design of the part, which is usually accomplished through computer-aided design (CAD) software. Once the design is finalized, a die is created that corresponds exactly to the desired shape of the part. This die is then used in a stamping press, where flat metal sheets, or coils, are fed into the machine. The stamping press exerts force on the metal, using the die to cut, bend, or form the material into the required shape.
