压铸产品是铸造液态模锻的一种方法， 一种在专用的压铸模锻机上完成的工艺。它的基本工艺过程是：金属液先低速或高速铸造充型进模具的型腔内，模具有活动的型腔面，它随着金属液的冷却过程加压锻造，既消除毛坯的缩孔缩松缺陷，也使毛坯的内部组织达到锻态的破碎晶粒。毛坯的综合机械性能得到显著的提高。

Die castingis acasting method ofliquiddie forgingprocess,aspecial die casting die forging.Its basic process is:the cavity of metalliquid islow or high speedcastinginto a mold,mould have activities of the cavity surface,themetal liquid cooling process pressure forging,can eliminatethe blank of shrinkage cavity shrinkage,also make the blank internal organization achieveforging state of crushing grain.Blank comprehensive mechanical performance wassignificantly improved.
