Aluminum die casting
Die casting is a manufacturing process in which molten metal is injected, under pressure, into a hardened steel die or also called mold. Dies are often water-cooled. Dies are then opened, and the die castings are ejected (many times thousands of parts each day, sometimes only a few hundred). Once the tooling is paid for, die casting is a very inexpensive aluminum part manufacturing process.
