Cold Chamber Die Casting Process
Cold chamber die casting is a permanent mold metal casting process. A reusable mold and gating system is employed. It is most likely machined precisely from two steel blocks. Large, robust machines are used to exert the extreme clamping force necessary to hold the two halves of the mold together against the tremendous pressures exerted during the manufacturing process.

During the cold-chamber die casting process, the molten metal for the casting is introduced to the shot chamber from an external source. Since the liquid metal is brought in from an outside source, the die casting machinery is able to stay much cooler in a cold-chamber process. Consequently, higher melting point alloys of aluminum, brass, copper, and aluminum-zinc are often metal cast in manufacturing industry using cold chamber die casting can be manufactured castings from lower melting point alloys using the cold-chamber method.
In the cold chamber die casting process, material must be brought in for every shot or cycle of production. This slows down the production rate for metal casting manufacture, however the cold chamber die casting should still be considered a high production manufacturing process.
