.... Aluminum may be cast into sand or iron molds. Low-melting-point metals (aluminum, magnesium, and zinc) may be die cast. In die casting, metal is forced into a metal mold that automatically opens and ejects the part as soon as it is frozen. The production rate is high but so are capital costs. In recent...
