Hot Chamber Zinc Castings. The best machine used in zinc die casting is the hot chamber. Hot chamber zinc casting is the familiar method used in zinc because it does not involve a very high temperature in order to melt the metal. Metals with high-melting point such as aluminum do not do well in hot chamber casting. There is a tendency that the metal will attract the iron in the machine. Hot chamber casting is used in other alloys that have low-melting point like copper and magnesium.
The method in hot chamber zinc casting begins with melting the block of zinc in the furnace. In order for zinc to reach its melting point, heat must be about 700-800 degrees Fahrenheit. As soon as the zinc achieves its melting point and turns liquid, it is then transferred through a shot sleeve. Known as the goose’s neck, the sleeve is immersed in the furnace and then inserted into the die. Pressure is applied until the zinc returns to its solid state while holding the shape of the die cast. To make the casting progression easier, lubricants are applied to the mold. This helps the elimination of the molded zinc as well as the control of the temperature easier. In some instances, robotics is engaged to remove the molded metal. The solidification process typically takes 2-15 seconds.
Other operations after the hot chamber zinc casting are completed to polish the molded metal. Such operations include trimming, painting and plating. This makes the details of the casted zinc more specific and serviceable.
