可膨胀聚苯乙烯材料发泡模的制造与控制

Producing and Controlling of Expandable Polystyrent Palterns

在实型铸造技术中，发泡模（可膨胀聚苯乙烯材料制成）对铸件的质量有很大影响。介绍发泡模的制造过程及其控制系统。

In lost foam casting patterns are made of the expondable polystyrene,which affecting the quality of the foundry preducts. This papor intreduces the principle of preducing fcatn potterns and the procese control.
