The development condition of light of casting parts for modern machines in the domestic and foreign indicate that castings made by the magnesium alloy have great potential in the application of industry and national defence. According to the analysis of casting method for magnesium alloy
it is becieved that production of large-scaled and complex castings at present is behindhand. With the rapid increasing of demands for alloy castings with light weight and for the casting technology and casting equipment to be further studied to
it is urgent accelerate the development of casting industry for light alloy in our country.
