What is Die Casting?

Die casting is a process that allows your manufacturer to produce parts with complex geometries, excellent dimensional accuracy, and smooth cast surfaces.

To create these parts, molten metal is forced into a mold cavity—which is made up of two hardened tool steel dies—using high pressure.

This process is well-suited for the high-volume production of aluminum, magnesium, zinc, copper, tin or lead parts. It is generally not appropriate for low-volume production because of the high tooling costs involved.

There are two main types of die casting processes that may be used to create your product—hot-chamber and cold-chamber die casting.

Hot-chamber die casting is generally used for zinc tin and lead, while cold-chamber die casting is used for aluminum and zinc alloys.
