Pressure casting process of many features, so that in improving the non-ferrous metal alloy casting the level of precision, production efficiency, surface quality, etc. show a great advantage. With the development of automobile, motorcycle and other industries, and to improve the quality of die casting, energy saving, reduce pollution and other design requirements, non-ferrous metal alloy die casting, especially light alloy (aluminum and magnesium alloy) die casting applications In the rapid expansion. Data show that: industrial countries with aluminum and magnesium alloy castings instead of steel castings is becoming an important development trend. Die casting has become the automotive aluminum alloy forming process is one of the most widely used in a variety of automotive molding technology accounted for 49%.

Since the 90s of the 20th century, China's non-ferrous metal die-casting industry has made amazing progress in the same time, has become an emerging industry. Now there are about 3,000 non-ferrous metal die-casting enterprises, die casting production rose from 266,000 t in 1995 to 870,000 t in 2005, an average annual increase rate of 12.58%, of which aluminum die casting die casting production accounted for all the 3 / 4 or more.

With the technical level and product development capabilities, aluminum die-casting products, the types and applications in the widening of its alloy types, die-casting equipment, die-casting molds and die-casting process have undergone tremendous changes.

New Development of Die Casting Aluminum Alloy

Die casting aluminum alloy has been put into commercial production since 1914, with the development of the automotive industry and the invention of cold chamber die casting machine, the alloy species has been rapid development. Die-casting aluminum alloy according to the performance can be divided into low-intensity (such as China's Y102) and high strength (such as China's Y112) two. Al-Si, Al-Si-Mg, AI-Si-Cu-Mg, Al-Zn and so on are mainly used in the following industries: Al-51, Al-Mg; Industrial developed countries the main die-casting aluminum alloy series.
