Most of the cavity mold of the isolation pier, especially the cavity of thermosetting plastic mould, must be heat treated. This requires that the steel has good hardenability and very little deformation. The mould for general thermoplastic forming can be treated by quenching and tempering, pre hardening and so on. Thermosetting plastic forming dies must be hardened. The concave cavity of the steel mould is often discharged by EDM, and the hardened layer on the surface after discharge is shallow so as to be easy to polish. Polishing is the most time-consuming in the cavity mold processing of the isolation pier. Longer hours increase costs. At present, the automatic polishing technology has not yet reached the practical stage, but still mainly manual polishing. When the hardened layer thickness is increased, the polishing time is increased.

国产隔离墩模具国内市场满足率一直不足74%,其中大型、精密、长寿命模具满足率更低。目前工业发达国家的模具正在加速向中国转移,国际采购越来越多。市场需求旺盛,生产发展一时还难以跟上,供不应求的局面还将持续一段时间。注塑模具企业不但要重视产品的研发,同时更要重视产品的创新。只有企业在技术人才、技术创新方面要具有雄厚的实力,同时能够在第一时间内准确把握客户的个性化需求,企业才能稳定飞速的发展。

The domestic market rate of isolating pier mold has been less than 74%, of which the large, precision, long life mold meets lower rate. At present, the mold of industrial developed countries is accelerating to transfer to China, more and more international procurement. Market demand is exuberant, production development is hard to keep up with, the situation of short supply will continue for a period of time. The injection mold enterprise should not only pay attention to product R & D, but also pay more attention to product innovation. Only enterprises in the technical personnel, technical innovation should have a strong strength, and at the same time in the first time to accurately grasp the individual needs of customers, enterprises in order to stable and rapid development.
