Aluminum die casting is a process where molten aluminum alloy is injected into a casting die under high pressure and at a controlled temperature. The mold has two sections, the “cover” half and the “ejector” half. The die may also have additional moveable segments called slides or pulls, which are used to create features such as undercuts or holes which are parallel to the parting line.

Aluminum die casting dies are run in cold chamber die casting machines. These machines are operated at the required temperatures and pressures to produce a quality part to net-shape or near net-shape specifications. Aluminum die castings can be readily machined, anodized, painted or powder coated.

Some of the more typical applications for aluminum die castings are: enclosures for the electronics industry, hand and power tools, hardware applications, pump parts, plumbing parts, parts for the automotive industries, sports and leisure, home appliances, and communications.
