Hi all,

I'm new to this forum. Yes I'm a toolmaker, don't shoot me!

We mould a lot of PSU here, and successfully too I might add, but we have one job that gives us problems, the parts are complex and don't demold well, and stick to the long cores. When we scuff the cores with 1200 paper, no problems, when we polish, the parts stick. I assume we are dealing with a vacuum break problem. Unfortunately the customer requires parts with better clarity than a 1200 finish can provide. Are any of you guys using a coating or surface treatment for molding clear PSU parts?

Thanks in advance,

Andrew
