Die casting (note that die casting is not the abbreviation of pressure casting)
Is a metal casting process characterized by the use of a mold cavity to apply high pressure to melted metal. Molds are usually made from stronger alloys in a process similar to injection molding.
Metal ingot is formed almost once, the cost is reduced and the production time is reduced to a certain extent by achieving the purpose of no machining or a small amount of machining.
Metal ingot is a relatively economical blank forming method, which can show its economy for the parts with complex shapes.
