摘要: Compared to traditional high-pressure die casting(HPDC),horizontal squeeze casting(HSC)is a more promising way fabricate high-integrity castings,owing reduced number of gas and shrinkage porosities produced in the casting.In this paper,the differences between HSC HPDC are assessed,through which it is shown that cavity filling velocity size gating system be most notable differences.Equipment development related applications also reviewed.Furthermore,numerical simulation used analyze three fundamental characteristics HSC:slow filling,squeeze feeding slow sleeve filling.From this,a selection principle given based on critical casting parameters:cavity velocity,gate velocity.Finally,two specific introduced,and future direction discussed.
