Below is a list of Die Castings manufacturers from Briarcliff Manor, New York. Die casting is a metal forming process in which molten metal is forced into mold cavities under high pressure and then cooled in order to form solid metal parts. Facilities where die castings are made are referred to as foundries. Die cast products are typically made from non-ferrous metal castings such as zinc, aluminum, copper, magnesium, lead, tin, bronze and some alloys; alloy tool steels may be formed through die casting as well, although the preferred fabrication method for steel parts is forging.
