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