Cold Chamber vs Hot Chamber Machines

The distinction between hot chamber  and cold chamber die casting for manufacturing is that cold-chamber has the molten metal pushed into the die from an external source.  The metal is heated and turned into molten metal outside the die cast machine.  Hot chamber machines the metal is melted in the machine.  Since the metal is melted inside the machine, certain parts of the machine has constant contact with the molten metal, therefore, metals with high melting temperatures are not typically cast with hot chamber machines.  Cold chamber machines are able to operate much cooler since the molten metal is brought in from an outside source.

Cold Chamber Die Casting Process

The molten metal is hand ladled or automatically poured into the shot chamber from the external holding container. A hydraulic or pneumatic cylinder forces a piston to push the molten metal into the mold with extreme pressure.  The pressure is maintained for a brief period of time until the metal starts to cool and solidify. The cylinder retracts, the  mold is open and injector pins remove the cast from the mold.  Prior to injecting the next mold, the mold is sprayed with a lubricant so the next cast will remove easily.

It is possible to cast low temperature metals using cold chamber process. However, higher production rates are possible using hot chamber machines since the metal does not have to be delivered from outside the machine. Hot chamber machines are typically employed when possible.  Cold chamber die casting is typically required for metals with high melting temperatures such as  of brass, copper and aluminum. Cold chamber machines will require significantly more pressure to force the high temperature molten metal into the mold than a hot chamber machine.
