同时提出，将化学复合镀与金属喷涂制模技术结合起来，可以提高复合材料模具的耐磨性及使用寿命。
At the same time, the method that combines composite electroless plating with metal spraying mold making to increase the wear resistance and operating life of composite mold is also proposed.
模具的寿命又与模具材料及热处理、模具结构以及所加工制作材料等诸多因素有关；模具的安装与使用直接关系到模具的使用性能及安全；
The mold life with the mold material and the heat treatment, the mold structure as well as processes the manufacture material related and so on many factors;
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。
The Foundry mould made by polyurethane can serce for 80,000 times, it is similar with the mould made by aluminum alloy.
