I have Jason's 8" curl tail worm mold, and Jason's 8" curl tail tip mold. I am making 2 color worms.
First I'd like to report that the tip mold shoots great, the worm mold itself shoots great.
I am having a slight problem getting good results when I put the curl (which was shot in the tip mold) into the worm mold, and then shooting the worm mold.
About 1/2 of the finished worms have a bubble within 1" of the spot that the tip and worm connect. It makes a weak spot in the worm. The two parts adhere fine, but the bubble weakens it.
I have tried getting the plastic a tad hotter, a tad cooler, shooting it a little slower, a little faster, holding it with the injector inserted longer, etc. It still leaves that weak bubble area in about half the worms I shoot.
I hope my explanation of the problem is understandable, and Thanks in advance for any ideas, tips, theories.
