Die Casting (English: die casting) is a metal casting process, which is characterized by using a mold cavity of molten metal high voltage is applied. Mold usually processed with higher strength alloys, the process is somewhat similar to the injection molding.

Most die-casting are free of iron, such as zinc, copper, aluminum, magnesium, lead, tin and pewter, and alloys thereof. Depending on the type of die-casting, it requires the use of a cold chamber die casting machines or hot chamber die casting machine.

Die casting equipment and high cost, so the die-casting process is generally only used in volume manufacturing a large number of products. Manufacture of die-cast parts is relatively easy, it generally requires four main steps, individual low incremental cost. Die-casting is particularly suitable for manufacturing a large number of small and medium sized castings, all kinds of die-casting process and therefore the most widely used one. Compared with other casting technology, casting surface is more smooth, with a higher dimensional consistency.

On the basis of the traditional die casting process on the birth of several improved processes, including reducing
casting porosity defect removal nonporous die casting process. Mainly used for processing zinc, can increase the direct injection technology to reduce waste yield. There are fine speed close-casting technology was developed by General
Dynamics and the invention of new semi-solid die-casting process and so on.
