China Die casting is the process of casting molten metal into the cavity at high pressure. The metal is hardened to obtain the desired shape. Recently, plastic moldings have changed die castings because they are cheaper and lighter than die castings. Can be used for cold or hot chamber process for die casting.

Die casting is a wide range of non-expendable technologies in which the metal is forced into the mold cavity under high pressure. Die-casting molds called molds can be reused to create castings of various sizes, shapes and walls. Mold cavity design complex, can be accurate, the surface smooth and attractive to produce complex shapes.

In the early stages of casting, only low pressure injection was used, but today's high pressure casting techniques such as extrusion casting and semi-solid die casting were used for casting more than 4500 psi. Initially only tin lead is dead, but now magnesium, copper and other alloys is also used this very popular way to casting.

In this process, the molten metal or other material is forced into the cavity of the steel mold under high pressure. The mold is made of alloy tool steel with two parts of the mold - the holder half mold and the ejector half mold. The mold or mold is made to have the impression of the part to be cast.

In modern times, the use of precision die-casting machine to ensure the consistency of quality. Each of the machined die-casts is different in the way the molten powder is poured into the mold. Automated for lubrication of the mold, the metal into the room and so on. Two processes, called hot and cold chamber methods, are used for die casting.

Die casting is best suited for casting medium parts with complex details. Die casting is the largest casting technology used in the manufacture of automotive, toy, sink faucet parts, connector housings, gears and other consumer products, commercial and industrial products. Most die castings are made of nonferrous metals such as aluminum, magnesium and so on.
