138 tons, available for the manufacture of Zinc, or magnesium castings.

Die casting can be done using a Hot chamber process In a hot chamber process the pressure chamber is connected to the die cavity is immersed permanently in the molten metal. The inlet of the pressurizing cylinder is uncovered as the plunger moves to the open ( unpressurized ) position. This allows a new charge of molten metal to fill the cavity and thus can fill the cavity faster than the cold chamber process. The hot chamber process is used for metal of low melting point and high fluidity such as, zinc, and lead that tend not to alloy easily with
steel at their melt temperatures.
