Die casting is a custom manufacturing process that produces engineered metal parts by injecting molten metal under very high pressure into reusable molds, called “dies,” made from premium tool steel. The dies can be designed to cast very complex shapes and sharply defined product features with a high degree of accuracy and repeatability, often with no post-casting machining required to meet part specifications. Unusually smooth surfaces can be produced as-cast, as well as a variety of textured surfaces. Die castings are suitable for a range of cosmetic finishes to match other mated parts or add extra durability in use.

Advanced high-pressure die casting, with some machines operating at die clamping forces exceeding 4500 pounds per square inch, is capable of producing net- or near-net-shape castings of high integrity and dimensional precision— at very high cycle speeds. A complete die casting cycle can vary from less than one second for small components weighing less than an ounce, to no more than two-to-three minutes for a casting of several pounds.

The process’ advantages make die casting the most efficient technology available for producing a wide range of commercial, industrial and consumer products in durable, rigid metal. A range of metals can be die cast, but the majority of die castings are non-ferrous parts, in aluminum, magnesium and zinc. High pressure die casting is an efficient, economical process that offers a broader range of shapes within closer tolerances than many other metal manufacturing techniques. Die cast parts are used in many industries including automotive, locomotive, agricultural, marine,  and plumbing.
