1、適當提高鋁合金壓鑄過程中的增壓壓力
、縮短增壓建壓時間

、加jia大da內nei澆jiao口kou厚hou度du。鋁lv合he金jin壓ya鑄zhu廠chang家jia通tong過guo這zhe樣yang的de方fang式shi來lai處chu理li壓ya鑄zhu件jian，可ke以yi延yan長chang內nei澆jiao口kou凝ning固gu時shi間jian，保bao持chi壓ya力li傳chuan遞di通tong道dao，讓rang還hai沒mei有you完wan全quan凝ning固gu的de壓ya鑄zhu件jian可ke以yi充chong分fen補bu縮suo壓ya實shi

，讓rang組zu織zhi更geng加jia致zhi密mi。

、適當提高壓室充滿度，廠家建議以鋁合金液體占壓室體積的60-70%左右比較合適。
