What is Die Casting?
Die casting is a metal casting process that manufactures metal parts by forcing molten metal into reusable molds, called dies. It is capable of producing sharp definitions and complex shapes from non-ferrous alloys, specifically zinc and aluminum. Depending on the melting temperature of the metal, a hot or cold chamber may be used.
Die Casting involves four main steps:
Die preparation – The die is made in two halves (fixed and ejector) and mounted in the die casting machine.
Casting – Molten metal is injected into the die cavity and solidifies quickly.
Ejection – An ejection mechanism pushes the casting out of the opened die after a set cooling time.
Trimming – Excess material attached to the casting is trimmed off.
