Die casting can be used to produce parts from zinc and aluminum, and is ideal for smaller pieces and more intricate part designs. Molds for die casting are created from hardened tool steel which is machined into the desired shape. Like those used in sand casting, die casting molds are built in two halves, which are separated after casting to remove the resulting part(s).
Molten metal is forced into the mold cavities under high pressure (up to 25,000 psi or greater), and this pressure is maintained until the casting cools and solidifies.
High pressure is necessary to fill the mold quickly, before any part of the casting solidifies. This process yields smooth part surfaces and can produce parts with thinner walls than other casting methods allow.
Die casting is an effective, cost-effective process offering a larger range of shapes and components than any other manufacturing technique. Engineers can gain many advantages by specifying die cast parts, some of the benefits of die casting include:
