[0002] Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to molten metal. The mold is usually made of a higher strength alloy, and the process is somewhat similar to injection molding. Most die cast parts are non-ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys, and their alloys. Die casting machines are used to inject molten metal into a mold under pressure, and after the mold is opened, a solid metal casting is obtained. Initially, it was used for die casting type; with the progress of science and technology and industrial production, especially with the development of the automobile, motorcycle and household appliance industries, die casting technology has developed rapidly.
