Hot Chamber Die Casting for Low Melting Point Alloys

Hot chamber die casting machines are primarily used for zinc, copper, lead and other low melting point alloys. The injection mechanism of a hot chamber machine is immersed in a molten metal bath of a metal holding furnace. The furnace is attached to the machine by a metal feeding system called the gooseneck.

As the injection cylinder plunger rises, a port in the injection cylinder opens allowing the molten metal to fill the cylinder. As the plunger moves downward, it seals the port and forces metal to fill the cavity through the gooseneck and nozzle to the die cavity.

After the metal has solidified in the cavity, the plunger is withdrawn. The die opens and the casting ejected.
