The progressive mold (metal stamping) is a mold designed to obtain the profile of a product with successive phases. That is, it is a tool for the transformation of sheet metal into a product with well-defined shapes. This transformation is carried out by cutting, punching, bending, or deformation on laminated metal materials (steel, iron, copper, brass, aluminum) carried out in subsequent stations. The mold is not an autonomous medium, for its operation it must be placed on a press (generic machine capable of exerting a force). On the edge of the press will be inserted a power supply unit whose task is to advance the coil (Coil) of a station at each press stroke.
