During cold-chamber die casting, the molten charge, which consists of more material than is required to fill the casting, is ladled from the crucible into a shot sleeve where a hydraulically operated plunger pushes the metal into the die. The extra material is used to force additional metal into the die cavity to compensate for shrinkage, which takes place during solidification.
The main components of a cold-chamber die casting machine are shown below. Injection pressure of over 10,000psi or 70,000KPa can be obtained from this type of machine.
