The experimental results of liquid extruded forming of casting iron are presented, such as the main parameters of squeezing temperature, unit extruding force, and holding time, etc. The mechanics performance data are got for the different process conditions. It is shown that the mechanics performance index of the parts made by this method is evidently improved than that of the parts made by the method of steel mould gravity casting, which mainly depends on three parameters of extruded force, time and holding time.
