Is concerned, automobile industry related to improve performance, saving energy, reduce cost, reduce pollution and so on many issues, they cannot reduce vehicle weight this key center issues. Reduce vehicle weight is one of the most effective ways of change material, using al-alloy castings (including foundry method) instead of ductile cast iron is a better choice.

　　And in all kinds of aluminum alloy castings, die-casting pieces in the most important position. Currently in automobile industry developed countries, the automobile engine cylinder, gearbox shell, straight hole type inlet manifold, the wheel hub, power steering gear rudder shell parts and other important has been widely adopted aluminium alloy die casting.

　　In recent years China's automobile yield appeared rapid growth and development trend of automobile lightweight, make light alloy die-casting pieces in the auto parts manufacturing application gradually to increase. Compared with developed countries, aluminium alloy die casting in the domestic auto parts manufacturers application development space is very big still, with domestic auto emissions environmental standards in the improvement and aluminum alloy die-casting technology advances, expected in China will have more auto parts using aluminum alloy die-casting technology manufacturing.
