泡沫塑料模型铸造法

Application of Full Mold Method of Foamed Plastics

用聚苯乙烯泡沫塑料制造模型浇注铸件,具有很多优点,是一种把泡沫塑料模型埋入无粘结剂砂内的工艺方法(干砂法)。本文介绍了以下该铸造技术的工艺现状及在铸件生产上的几个应用实例。

Making castings by plastic molds of polystyrene foamed plastics is a good practice which is a method by which the foamed plastics mold is burried in the sand without any bondings (dry sand method).This article describes the state of art and lists some practical examples.
