Die-casting is a metal casting process, which is characterized by using a mold cavity for molten metal high voltage is applied. The mold is usually processed with a higher strength alloy, this process is somewhat similar to injection molding. Most die-castings are free of iron, such as zinc, copper, aluminum, magnesium, lead, tin and pewter, and alloys thereof. Depending on the type of die-casting, cold chamber die casting machines need to use or hot chamber die casting machine.

Die casting equipment and high cost, therefore die casting process usually only used for batch manufacturing a large number of products. Manufacture of die-cast parts is relatively easy, which generally only requires four main steps, individual low incremental cost. Die-casting is particularly suitable for manufacturing a large number of small and medium sized castings, so die-casting process is used in a variety of the most widely used. 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 defects exclude nonporous die casting process. Mainly used for processing of 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.
