[0002] Die casting is a metal casting process characterized by the use of high pressure to fill an impression in a die cavity, the die cavity being the inside of a mold that gives a desired shape to a part, which is usually a metal. The die is typically made from stronger materials than the part being formed and traditionally preheated before use. It has an inlet through which liquid metal is introduced to the die. Once the liquid metal has taken the shape of the die, it solidifies into a metal part having thin walls and a good surface finish suitable for use without further machining. Most die casting metals, like aluminum, magnesium, zinc, lead, copper, and tin, are non-ferrous, meaning they do not contain iron. Die casting is mostly used for making complex shapes of high volumes. Most die cast parts are metal, but die casting can also be used with other materials, such as: glass, carbon, or even ice.
