脱模剂要打好噢！

soundsee

一个漂亮的模具做好了，就要投入生产了，可一定要打好脱模剂呀！如此费银子的东东一旦脱模剂没打好，可就废了。国内目前多数用的都是进口的8#蜡或者蓝蜡。打完后，要停一段时间擦去表层的浮蜡再打，一般新模具要打3~4遍。打完后也要做一下试验，确保不会粘模了。打蜡时为了让蜡层充分形成固化，打上新蜡后，不妨在太阳底下晒上一两个小时，保证擦蜡的工人再擦蜡时能出一顿大汗，比蒸桑拿出得多。而且第二天一定会腰酸背疼，但效果确是不错。

新版的PMR，好像成膜印痕少了些，但有效组分也一样被降低了，连续脱模次数减少了。

其实，半永久性脱模剂，还有个美国牌子，AXEL，也不错。

好久远的帖子，不过精华，学习一下

jasminexyc

这贴才是精华帖子，受益匪浅呐。
其实关于前面提到的封孔剂，那个玩意儿完全可以用8号蜡代替，在新模具表面打8号蜡，用作封孔，然后再打脱模剂，这样反复操作三五次，保证你脱起模来爽的不得了。
需要汉高乐泰770NC脱模剂的请联系联系哈，保证物美价廉。

      这样操作不行吧，之前打蜡，后续在打脱模剂，脱模剂就会把腊给溶解掉，这样的话之前打的腊，没有任何意义了，而且严重的话，会起冲突，导致粘模。
  使用 脱模产品的话，建议要不纯粹打蜡或者脱模剂，实在为了保险混合用，先打脱模剂，后打腊。

不是遇到了一些疑难杂症，真不建议不同类型的脱模剂混用！
