Aluminum Casting Process

Permanent Mold Casting

Much of the expense of aluminum permanent mold casting is the machining and shaping of the mold, which is normally made from gray iron or steel. The mold is shaped into the geometric shape of the designed part with the specifications and shape of the part divided into two halves. In the injection process, the halves of the mold are tightly sealed such that no air or contaminants are present. The mold is heated prior to the pouring of the molten aluminum, which can be ladled or injected.

At the completion of the process, the mold is allowed to cool to allow the aluminum part to solidify. Once cooled, the part is rapidly removed from the mold to prevent the formation of defects.
