Hot-Chamber Die Casting

Definition of Hot chamber Die casting

When the port seals, the metal rests in the cavity to cool and solidify. Next, the plunger retracts and the casting itself can be removed once the die opens. This design allows the hot chamber die casting to be a continuous process.

Because the melting pot is internal, hot chamber machinery is used for materials with lower melting points. The alloys are also limited to materials that won’t erode or dissolve the metal of the machine when put under heat or high pressure. Typical materials used in hot chamber die casting are zinc, lead and magnesium alloys.
