Cold chamber die casting is ideal for metals with high melting points and corrosive properties, like aluminum.

Unlike the hot chamber die casting process, cold chamber solves the corrosion problem by separating the melt pot from the injector components. In the cold-chamber process, metal is transferred by ladle, manually or automatically, to the shot sleeve. Actuation of the injection piston forces the metal into the die—this is a single shot operation. This procedure minimizes the contact time between the hot metal and the injector components, which helps to extend their operating life.

It is possible to cast lower melting point alloys using the cold chamber process but when you consider the advantages of the hot chamber process it usually makes more economical sense to use the hot chamber method for metals like zinc and magnesium.

There are different processes and recommendations for each different metal. If you are interested in starting a new die casting project, it is best to involve our team of engineers for installation of manhine.
