Die casting is a metal casting process, the molten metal is poured into the mold, the shape or shape required to produce the desired shape. Non ferrous metals such as copper, aluminum, zinc and other non-ferrous metal castings are mainly used. Die casting equipment and a large capital costs, which tend to limit the high-volume production process. Use molded parts manufacturing is relatively simple and only involves four main steps, which makes the incremental cost per item is low. It is particularly suitable for large quantities of small to medium-sized castings, which is why the die-casting production more than any other casting process, the casting is characterized by a very good surface finish (by casting standards) and dimensional consistency.
