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.

Die Casting Applications

Industrial components
Die-cast parts are strong and durable, making them suitable for use in demanding industrial applications, such as pumps, valves, and compressors.


Appliance housing
Die casting can produce parts with thin walls often required in the manufacture of metal housings for tools and appliances.


Consumer Products
The ability to replicate complex designs to detail make die casting a cost-effective method of mass producing small to medium-sized toys or consumer goods.

Die Casting Benefits

Quantity and Speed
Die casting is economical as it can produce large quantities quickly and with little labor involved.


Die-cast parts are strong and durable.


The die casting process maintains dimensional stability and close tolerances across its production.


Detailed Finish
Die-cast parts can produce parts with complex shapes to a fine detail, with smooth or textured surface.
