How does the die casting process work?
A – Die casting is frequently referred to as the fastest route between raw material and finished product. Because of the differences in the melting temperatures of various die casting alloys, two methods of inserting the molten metal into the die cavities are used. These are referred to as hot chamber and cold chamber machines. Hot Chamber Hot chamber or plunger machines are used mainly for zinc alloys. With modern technology, this process is increasingly being used for magnesium. The hot chamber process is a preferred die casting method due to its high rate of productivity. However, it cannot be used for some high melting point alloys or for those alloys which attack the steel working parts of the machine. Operating sequence for the hot chamber die casting process: 1. Die is closed and gooseneck cylinder is filled with molten metal. 2. Plunger pushes molten metal through gooseneck passage and nozzle and into the die cavity. Metal is held under pressure until it solidifies. 3. Die open
