Brief OverviewIdeal for mid to high-volume production, die casting is the equal to injection molding for many geometries that need to be made in metal. The process involves the creation of a die into which the designated alloy is shot under high pressure (1,500 – 25,000 psi). Following the solidification of the part or parts in the die and, similar to injection molding, after the part is ejected by the ejector pins the gating is then removed. The removal of the gating is either done manually or automated. Materials include aluminum, magnesium, copper and zinc. Standard tolerances range from .005” / 0.127 mm. For each inch after the first inch, the tolerances are + 0.002” / 0.05mm.
