Die cast parts aluminium and zinc

Die casting is the process of forcing molten metal under high pressure into mold cavities (which are machined into dies). Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, and tin based alloys , but ferrous metal die castings are possible. The die casting method is especially suited for applications where a large quantity of small to medium sized parts are needed with good detail, a fine surface quality and dimensional consistency. This level of versatility has placed die castings among the highest volume products made in the metalworking industry. In recent years, injection-molded plastic parts have replaced some die castings because they are cheaper and lighter.Plastic parts are a practical alternative if hardness is not required and little strength is needed.
