聚氨酯铸造模具的应用与发展

Application and Development of A Style of Foundry Mould Made by Polyurethane

用聚氨酯材料制造的铸造模具 ,使用寿命可达 8万次 ,与铝合金模具相当。介绍近年国外聚氨酯铸造模具材料性能 ,制成模具后的力学性能、耐磨性的情况以及制造聚氨酯模具的工艺方法。

The Foundry mould made by polyurethane can serce for 80,000 times, it is similar with the mould made by aluminum alloy. The foundry mould made by polyurethane abroad from aspects of mechanical property, wear-resistant condition, and technology method have been introduced.
