Ultimate Predators Posted September 29, 2016 Report Share Posted September 29, 2016 I have now completed my Soft Plastic delivery system in 3 styles all concepts and drawings at this point. Thanks for all the help. I'm trying to assemble a working system with parts bait makers have and stuff that can be purchased to keep the cost down. I believe I have a solid idea now. The only thing that I'm not sure of yet is, Does Plastisol, when heated to the proper temperature, pour into a aluminum mold (not injected) right down the center of the hole and fill the cavity to make a bait correctly ? This is one of my 3 designs if it works. Quote Link to comment Share on other sites More sharing options...
Apdriver Posted September 29, 2016 Report Share Posted September 29, 2016 There are three different aluminum bait molds. 1. Injection mold 2. Hand pour mold (closed mold) 3. Open pour mold, hand poured. The difference in the injection mold and closed hand pour mold is usually in the opening and the venting. More venting is needed in the hand pour because there is no pressure as you introduce the plastisol. It's poured into the cavities. So the answer to your question is yes, it is poured in right down the hole on that type of mold. That said, most of us inject anymore and the mold producers don't make many hand pour molds. Mostly it's injection molds. Good luck with your project. Quote Link to comment Share on other sites More sharing options...
MonteSS Posted September 29, 2016 Report Share Posted September 29, 2016 (edited) Only aluminum two piece mold that works decent is a stick or straight tail worm. Thin curly tails, claws, legs etc wont fill very well if at all Edited September 29, 2016 by MonteSS Quote Link to comment Share on other sites More sharing options...
Ultimate Predators Posted September 29, 2016 Author Report Share Posted September 29, 2016 Thank you gentleman that eliminates one of my ideas to pour accurately down an injection mold hole and get a good bait, that's one thing I never tried cause I know it doesn't work pouring by hand. Now on to the injection system. Quote Link to comment Share on other sites More sharing options...
Jig Man Posted September 29, 2016 Report Share Posted September 29, 2016 Even pouring a worm I use spru extenders. Quote Link to comment Share on other sites More sharing options...
kayaksticks Posted September 29, 2016 Report Share Posted September 29, 2016 depends on the mold. I hand pour my BJ's Ledger swimbaits. Some molds intended for injection can be hand poured. the only ones I have been able to hand pour is single cavity with a top inject.

mark poulson Posted September 29, 2016 Report Share Posted September 29, 2016 I have a 10 cavity fat Ika two piece aluminum mold that I hand pour. The cavities are individual, with 1/2"+- top pour sprue holes. Every other two piece aluminum mold I pour I inject, and most of my pop molds, too.
