GB GONE Posted March 24, 2011 Report Share Posted March 24, 2011 You should not need a release agent for any molds, regardless of their type. If you do, there is an issue with the mold surface. Jim Quote Link to comment Share on other sites More sharing options...

Jim I have a bout 500+ resin molds and produce about 3000-4000 pieces per week. I do use worm oil as a release agent. I make my models out of molder's clay and then make a "test" mold. If I like it, I then cast a silicone mold of the resin mold (a positive mold) and then copy the mold to as many cavities as I need. I have noticed that the test mold is MUCH more likely to need a release agent than the copies. The plastic never completely sticks, but since I use pretty soft plastic, and I would otherwise have to wait about thirty minutesfor the plastic to completely cool to demold. I am looking into getting a silicone based domlding agent. My plastic supplier is getting a sample for me. It is supposed to be sprayed on once every 30-40 castings and provide a shiny surface. We'll see. Stephen Gula Baits 1 Quote Link to comment Share on other sites More sharing options...
GB GONE Posted March 24, 2011 Report Share Posted March 24, 2011 I guess what I meant was, you should not HAVE to use a de-molding agent. You can CHOOSE to use one though and worm oil, PAM spray and others are available. Be sure to test them well prior to use and also test for the long term affects on your baits. Some changes may occur a week to a month out there. Jim Quote Link to comment Share on other sites More sharing options...
robalo01 Posted March 24, 2011 Report Share Posted March 24, 2011 Don't use Softner as release agent!! make baits sticky. Quote Link to comment Share on other sites More sharing options...
