Joelh831 Posted March 27, 2017 Report Share Posted March 27, 2017 Hey guys so I started to do open pour swimbaits. But I'm haveing an annoying issue. I get a tone of half bubbles/ dimples/indentations all around the bait. The mold is clean and super smooth on the inside. What's causing this.

mark poulson Posted March 27, 2017 Report Share Posted March 27, 2017 What type of mold are you using? Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted March 27, 2017 Report Share Posted March 27, 2017 Please post a picture of the mold as well a good close up off the cavity, Leonard Quote Link to comment Share on other sites More sharing options...
Joelh831 Posted March 27, 2017 Author Report Share Posted March 27, 2017 It's a open pour silicon using alumilite I'll take a close up of the inside but I've felt it and theirs no indentation in it it's really smooth. Quote Link to comment Share on other sites More sharing options...
BHLures Posted March 27, 2017 Report Share Posted March 27, 2017 Too much release spray will do that. Are you using anything like a umr spray or worm oil to lube the mold? Quote Link to comment Share on other sites More sharing options...
Joelh831 Posted March 27, 2017 Author Report Share Posted March 27, 2017 I'm not using anything just straight from the microwave stirring it up then I let it sit till about 330 degrees and pour right into the mold I don't heat up the mold or use any oils or sprays Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted March 27, 2017 Report Share Posted March 27, 2017 Did you degass the alumalite prior to, If there is a bunch of air bubbles under the surface maybe they are expanding with the heat from the plastic. Quote Link to comment Share on other sites More sharing options...
Joelh831 Posted March 27, 2017 Author Report Share Posted March 27, 2017 I didn't. Honestly I don't even know how to do that or what that is. am I supposed to do something to the plastisol as well. I just shake the heck out of it and heat it up add color and flake and straight to the mold Quote Link to comment Share on other sites More sharing options...
Anglinarcher Posted March 27, 2017 Report Share Posted March 27, 2017 I really think your mixing air bubbles into the plastic. Degassing the silicone when making the mold is not necessary. Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted March 27, 2017 Report Share Posted March 27, 2017 The master has spoken, even tho you told me on the phone, the plastic was crystal clear. Quote Link to comment Share on other sites More sharing options...
Joelh831 Posted March 27, 2017 Author Report Share Posted March 27, 2017 Yea i tried heating up the mold prior to pouring to about 160-170 and it did help out. Another thing I noticed was I did have some air bubbles in the plastisol but I remelted the one I was using last night. What's the best way to mix it without introducing air into the mix or how do I let it sit so the can come up to the top without it cooling down to much to where I can pour it anymore thanks Quote Link to comment Share on other sites More sharing options...

Been there done that. These guys will help you figure it out for sure. Edited March 28, 2017 by Les Young Quote Link to comment Share on other sites More sharing options...
