Hot Chamber Die Casting for Low Melting Point Alloys

Hot chamber die casting machines are primarily used for zinc alloys, 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After the metal has solidified in the cavity, the plunger is withdrawn.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.

We Can Help with Low Melting Point Alloys

If you have a project that uses low melting point alloys, SKS may be able to help.  Depending on the demands of your application, SKS Die Casting may use cold chamber die casting in place of the hot chamber casting process. 

Please contact our die casting experts to help you select the best process to meet the needs of your die casting project, or request a quote on your hot chamber die casting project today.

SKS is your premier source for die casting and machining since 1945.
