Die casting
Die casting is a metal moulding process. The two pieces of the mould are referred to as the dies and together they create a chamber. Molten metal is forced at pressure between the hot or cold dies to create the desired shape prior to cooling.
The process is very similar to injection moulding which is used in the plastics and polymer industry.
A die in die casting is normally a hardened steel mould with a high melting point if used in hot casting, in order retain shape and consistency during the processing of the other metal being processed - such as zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys.
