Die casting is the equivalent of injection molding for various geometries that need to be created in metal and is ideal for mid to high-volume production. The procedure begins with the manufacture of a die into which a high-pressure (1,500–25,000 psi) shot of the desired alloy is fired. The gating is removed once the part or pieces have solidified in the die and, similarly to injection molding, after the part has been expelled by the ejector pins.
