robalo01 Posted February 8, 2010 Report Share Posted February 8, 2010 I'm injecting Bear's 5.25" side-port mold. WIth one color, no problem, eveything comes out great, but whenI add a tip, and then pour i get one or two bubbles (ranging from bb to a pea) in the top cavity near the tail/body splice. I assume air is getting trapped in there and the vent is stopped by the pre-poured tail. Strange thin is, that even if i try and leave the top cavity solid (no tail insert), i still get the bubbles. Would adding an additional vent at the splice be effective? or, am I ruining the mold? Quote Link to comment Share on other sites More sharing options...

Try warming the mold a little first. Quote Link to comment Share on other sites More sharing options...
Richard Prager Posted February 9, 2010 Report Share Posted February 9, 2010 Have you tried talking to Bear? I think I would do that before I started cutting on a mold. Try warming the mold a little first. Are you topping off the mold? You need to do that on the multi-cavity hand inject molds. Quote Link to comment Share on other sites More sharing options...
robalo01 Posted February 9, 2010 Author Report Share Posted February 9, 2010 1. It tends to gert worse as the mold worms up, so that isn't the problem. 2. I don't have dents (ususally associated to shrinking plastic), I do top offthe molds. And, the problem doesn't appear with single colored baits, only with colored-pre-poured tips. Has anyone else experienced this? I tried injecting faster, slower; raising and lowering the temp of the plastic, with no noticable diference.

bear21211 Posted February 9, 2010 Report Share Posted February 9, 2010 (edited) Robalo The mold has vents machined on the face of the mold so the mold is vented. I have shot quite a few of these and do not have to change the way I shoot the molds. I have not had anyone else have this problem that I know of yet. Give me a call tomorrow and I will do what it takes to get you going. Maybe something is wrong with the mold and I need to swap it out. I do not know what is going on with it as I have not any complaints before this one. I wish I could tell you what was going on with it but I do not know. Call me and I will swap the mold out and try that. Bear 985-969-1390 Is the pre poured tip covering a vent hole ??
