Pressure casting process of many characteristics, to improve its non-ferrous metal alloy casting accuracy level, production efficiency, surface quality, etc. show a great advantage. With the development of automobile, motorcycle and other industries, as well as to improve the quality of die casting, saving energy consumption, reduce pollution and other design requirements to achieve, non-ferrous metal alloy die casting, especially light alloy (aluminum and magnesium alloy) die casting applications In the rapid expansion. Data show that: industrial developed countries with aluminum and magnesium alloy castings instead of steel castings is becoming an important development trend. At present, die casting has become one of the most widely used processes in the aluminum alloy forming process for automobiles, accounting for 49% of various automotive molding processes.

Since the 90s of the 20th century, China's non-ferrous metal die-casting industry in the amazing development at the same time, has become a new industry. The country has a total of about 3,000 non-ferrous metal die-casting enterprises, die casting production from 266,000 t in 1995 rose to 870,000 t in 2005, the average annual rate of 12.58%, of which aluminum die casting accounted for all die casting production 3 / 4 or more.

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

New Progress of Die Casting Aluminum Alloy

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