2
、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。

3、適shi當dang降jiang低di壓ya射she速su度du，尤you其qi是shi慢man壓ya射she階jie段duan。鋁lv合he金jin壓ya鑄zhu廠chang家jia發fa現xian，較jiao快kuai的de慢man壓ya射she速su度du會hui將jiang壓ya室shi中zhong的de氣qi體ti卷juan入ru合he金jin液ye並bing帶dai入ru零ling件jian。相xiang反fan
，較jiao低di的de慢man壓ya射she速su度du更geng容rong易yi讓rang壓ya室shi中zhong的de氣qi體ti迅xun速su排pai出chu
，有you效xiao提ti高gao壓ya鑄zhu件jian的de致zhi密mi性xing。
