Die casting (English: die casting) is a metal casting process, characterized by the use of mold cavities impose pressure on the molten metal. Mold usually is formed by the higher strength alloy processing, a process similar to injection molding. Most die castings are not contain iron, such as aluminum, magnesium, zinc, copper, lead, Tin and pewter as well as their alloys. According to the different types of die-cast, need a cold Chamber die casting machine or hot Chamber die casting machines.

Foundry equipment and high cost of mold, die casting process is generally only used for bulk manufacturing of products. Manufacture of die-cast parts is relatively easy, which usually require only four main steps, individual incremental cost is very low. Die casting is particularly suitable for making a lot of small and medium sized castings, casting is one of the most widely used in the casting process. Compared with other casting, die casting surface more smooth, have a higher size consistency.

In traditional die casting process on the basis of the birth of the improved process, including reduced casting defects excluded stomatal pore-free die casting process. Zinc is mainly used for processing, you can reduce waste increase the yield of direct-injection technology. Also developed by General Dynamics of fine casting speed key technologies and semi-solid die casting new die casting process.
