PVL91501 Posted July 3, 2020 Report Share Posted July 3, 2020 New to making my own soft plastics and have not been able to find this particular issue discussed (though I did not dig deep). My capsule oring gets coated with plastic and sucked back into the injector tube. What am I doing wrong? Obviously, I then have to waste time removing all the stuck plastic. I've been lubing both with worm oil and preheating the injector and molds prior to shooting. No problem with the plunger oring. Any helpful hints, tricks, suggestions would be greatly appreciated.

basskat Posted July 4, 2020 Report Share Posted July 4, 2020 What temp are you shooting at? I shoot as cool as the mold will allow me. At lower temps the plastic is not quiet as thin which should help with your O ring issue. You may need to replace the O ring. 1 Quote Link to comment Share on other sites More sharing options...
PVL91501 Posted July 4, 2020 Author Report Share Posted July 4, 2020 I’ve been trying to shoot 330-345. I’m pretty sure you’re right, been shooting too hot. I’m going to store to get new orings tomorrow. Thx PVL Quote Link to comment Share on other sites More sharing options...
