Zinc Die Casting Process is Direct Injection Zinc Die Casting for Cast Metal Parts. The zinc die casting process involves heat, pressure and of course, zinc to produce metal castings. With the help of machines especially designed to apply and handle these three elements, when combined together produces zinc dies. The machine used in the zinc die casting process is the hot-chamber machine.
The zinc metal die casting process begins when zinc is placed on a very high temperature. The high temperature is then absorbed by the zinc. The zinc becomes soft and malleable. While the zinc is at its malleable state, it is shot at high pressure (usually 1,500 to 25,000 psi.) into the die. The die is lubricated beforehand. The lubrication in the die has a two-fold purpose. First, the lubricant enables the zinc to be easily removed from the mold. Second, it allows the temperature in the mold to be easily controlled. Upon injection of the heated zinc, pressure is then applied to the mold until the soft zinc solidifies.
Direct-injection die casting is also used in the zinc die casting process. Also known as runner-less die casting, this procedure is employed in zinc die casting as it has many advantages. It has slower cooling cycles which enables it to produce better results. The cost of using this process is also cheaper as it does not use much energy.
Zinc die casting is preferred by many industries. This is because zinc is the metal which is the easiest to cast but still produces great outputs. It works well on small areas and lasts a long time.
The Direct Injection process is pretty complicated, Peter.
