The Casting Process

Cold-Chamber Die Casting

In cold-chamber die casting the molten charge (a calculated amount of material, more than is required to fill the casting) is added into a shot sleeve from the crucible, where a hydraulically operated plunger pushes the metal into the die.

Operating Sequence of the Cold-Chamber Die Casting Process

1

The die is closed and the molten metal is poured into the cold-chamber shot sleeve.

2

The plunger pushes the molten metal into the die cavity where it is held under pressure until  solidification.

3

The die opens and the plunger advances, to ensure that the casting remains in the ejector die. Cores, if any, retract.

4

Ejector pins push the casting out of the ejector die and the plunger returns to its original position.
