怎样提高压铸件的密度和消除砂眼黑龙江省阿城继电器厂卢祥成，王锡胜，崔景霞在继电器产品中有不少凸起支柱的压铸件，在支柱顶部常会出现压铸缺陷和不容易发现的内部砂眼，我厂过电流继电器底座就是其中一例。由于压铸模型腔的几何形状复杂，熔铝在型腔内流动时产生涡流... How to improve the density of die-casting parts and eliminate the blister Heilongjiang Province Chengcheng Relay Factory Lu Xiangcheng, Wang Xisheng, Cui Jingxia relay products have a lot of protruding die-castings, the top of the pillars often appear die-casting defects and not easy to find internal blisters, I Factory over-current relay base is one example. Due to the complex geometry of die-casting mold cavity, eddy current is generated when molten aluminum flows in the cavity.
