Shaping of metal products by forcing a molten metal or alloy under high pressure into a negative-cavity die by means of a hydraulic ram. The die is usually made of an alloy steel. Metals commonly used for die casting are zinc, aluminum, copper, lead and their alloys, some of which also include silicon. Die castings can be held to tolerances as low as 0.001–0.0015 inches, and sizes 75–100 lb (Al) are possible. The largest end-use area for die castings is automobile and airplane parts. They are also used in washing and drying machines, in electrical equipment and appliances, and for various military applications.
