Based on the practical experiences in squeezing casting aluminum alloy

some key factors in whole processing procedures were proposed according to equipment structure and parts features.The available suggestions were proposed.In squeezing casting

the pouring temperature should be higher than that in common die casting

and the elemental Si

Mg

Cu and Fe content in liquid aluminum alloy should be strictly controlled

and the wider section area of ingate and shorter sprue should be adopted.In addition

the shift position of injection velocity from filling sprue to fill cavity as well as to high velocity filling should be strictly set

and the exhausted and dross design with larger channel should be adopted.Some bottleneck problems in the squeezing casting industry at domestic were discussed

and the future development was suggested.
