elru Posted June 20, 2017 Report Share Posted June 20, 2017 Hi guys so im having a problem shooting some worms to be exact round finess worm and a strech 40 type lure. Both molds are hand pour molds but i use my injector on them. Everytime i shoot them only one of four lures come out right the rest have dents in them where the plastisol doesnt take on the molds shape. So question is what can i do to eliminate this problem or what am i doing wrong? Quote Link to comment Share on other sites More sharing options...
AZ Fisher Posted June 20, 2017 Report Share Posted June 20, 2017 I'm not a plastics guy, but if you search "Dents" in this forum, you will find a bunch of posts on the subject. Welcome to TU! Quote Link to comment Share on other sites More sharing options...
Ferree Posted June 20, 2017 Report Share Posted June 20, 2017 Elru, are you filling the sprue after you inject to keep the plastic moving as it cools and pulls into the mold? keep it full until it stops sucking it in. Quote Link to comment Share on other sites More sharing options...

Cub48 Posted June 22, 2017 Report Share Posted June 22, 2017 Cooler plastic will dent less keep pressure on injector for a count of 10 or more fill spur Cub48 Quote Link to comment Share on other sites More sharing options...
mark poulson Posted June 22, 2017 Report Share Posted June 22, 2017 Cooler plastic, and holding pressure should do the trick, but it has it's own issues. As seems to be my wont, I shot myself in the foot again. This time, I made a 6 individual cavity pop mold with a fat, long profile. Because I wanted to keep denting to a minimum, I injected at 325. Because I hold pressure on the injector for a five count before I move to the next cavity, I can only inject four cavities before the plastic cools too much. I don't preheat my injector, which I'm sure would help. The mold came out good, so I'll just do four cavities at a time, and be happy that it works.
