Tool And Die Making
Tool and die making, the industrial art of manufacturing stamping dies, plastics molds, and jigs and fixtures to be used in the mass production of solid objects. The fabrication of pressworking dies constitutes the major part of the work done in tool and die shops. Most pressworking dies are utilized in the fabrication of sheet-metal parts that range in size from the finger stop on a dial telephone to the panels of an automobile body.
Each pressworking die consists of two sections, called punch and die, or male and female. Both sections are mounted firmly in an electrically or hydraulically driven press. In a working cycle the press ram, on which the male section is mounted, descends into the fixed female section. Any metal interposed between the sections is cut or shaped to a prescribed form. Like the dies, the presses range in size from extremely small to gigantic. A bench press is often small enough to be picked up manually; but the press that stamps out the roof of a car is generally about three stories high and capable of exerting tons of force.
