golfs321 Posted July 13, 2009 Report Share Posted July 13, 2009 I cant seem to get my plastic to pour right. Im using saltwater formula plastic and heating it in a microwave in 30-45 second increments until it becomes plastic like. I stir it and then pour it into my sealed POP mold going from one side to the other. Im pouring from a pyrex cup. Im pouring into fluke and sluggo molds. I can seem to get the top to be even on any of the baits, nor can I pour the thin tails of the flukes. If I do get a good pour, I sometimes get air bubbles coming out of the top of my bait after it is poured into the mold. I have tried barely heating it enough to become plastic, and ive tried heating it more. I hope you guys can give me some advice! Quote Link to comment Share on other sites More sharing options...
longhorn Posted July 13, 2009 Report Share Posted July 13, 2009 Sounds like you're not heating the plastic enough. When it's ready to pour it should be like hot pancake syrup, not thick or plastic like. Then the molds fill up to the top with no problem. Make sure your mold is level when you pour. I've got POP molds that I've had to shim on the bottom because the surface I made them on wasn't level. I'd bet the bubbles are from a pinhole or holes in the mold seal. Sometimes it takes several coats of seal to get a mold covered. If you look at the bait that came out of the cavity that bubbled you can usually see where the problem area is Good Luck Quote Link to comment Share on other sites More sharing options...
Jig Man Posted July 13, 2009 Report Share Posted July 13, 2009 You may have to build yourself an injector. I have a few baits that just won't pour. Quote Link to comment Share on other sites More sharing options...
96dak Posted July 13, 2009 Report Share Posted July 13, 2009 considering he's pouring one piece molds that's not really an issue. your not getting the plastic hot enough, get yourself an infrared thermometer and make sure you heat your plastic to 350 - 360 degrees F. you will be ready to pour at that temp Quote Link to comment Share on other sites More sharing options...
gone2long Posted July 13, 2009 Report Share Posted July 13, 2009 Also consider pre-heating your fluke mold as this will help pouring the tail, the cool mold will set the tail to quickly when your learning but it will come in time I had the same issue.

golfs321 Posted July 13, 2009 Author Report Share Posted July 13, 2009 im going to reseal my molds. I heated the plastic more and did better with my fluke molds...no bubbles at all! But im still having trouble pouring the very thin tails. I almost always have to trim around the tails at the end! My sluggo molds are the only ones that get air pockets and bubbles now. These are the ones I am going to reseal Quote Link to comment Share on other sites More sharing options...
Richard Prager Posted July 13, 2009 Report Share Posted July 13, 2009 You should have better control if you use less plastic in the cup and pour in all one continuous motion. also, Anchor brand makes a smaller 8 0z version cup that I use for harder to pour molds.

After you get them filled just set the mold back level and finish the cavity. Someday, you may want to consider getting a Presto pot. When set up right, they are very easy to pour small parts with because you can control the flow easier. Just my , JIM Quote Link to comment Share on other sites More sharing options...
