BuMMeRBaits Posted June 7, 2004 Report Share Posted June 7, 2004 I have been noticing after my last few pours, that the bottom of the worms I am pouring seem to be forming a concave shape to them after the have started to cool down in the molds. I have done everything to think of even over pouring (which helps). Alot of times even if I pour the plastic to the point that it is about to overflow it still does this. Has anyone else had this problem and/or know how to help it from being so bad. Quote Link to comment Share on other sites More sharing options...
AustinTXAngler Posted June 7, 2004 Report Share Posted June 7, 2004 What is the temp of your plastic when pouring? Maybe your pouring to hot and fast? Also, maybe your molds are too cold when you pour them which causes the plastic to shrink up??? Try warming the molds some and then pouring. I'm still new to pouring so I may be totally off track. Can anyone else confirm what I suggested? Quote Link to comment Share on other sites More sharing options...
Delw Posted June 7, 2004 Report Share Posted June 7, 2004 AustinTXAngler I believe is correct, when the plastic cools it shrinks one way to fix it is to pour right over the top again or let the plastic cool a tad more Delw Quote Link to comment Share on other sites More sharing options...
vishezfish Posted June 7, 2004 Report Share Posted June 7, 2004 I did all that Delw and the guys on the web said to do, and alot of times i still get that too!! But after afew pours, the mold will warm up, and no problem after they arm up... Like they said, the mold warming up will help and the temp of your plastic too.. I was pouring with the plastic smoking!! That was too hot, I wait a few seconds, look at the plastic and see how hot/ or what stage its in, then i pour.... I'm also using remelted plastics.... But it works for now!! Vishez fish Quote Link to comment Share on other sites More sharing options...
Tm Customs Posted June 8, 2004 Report Share Posted June 8, 2004 I had the same promblem in the begining pour the plastic cooler so you can get an almost rounded bottom, when its cooler it wont overflow out of the mold and you can pile it up as high as you want.

AustinTXAngler Posted June 8, 2004 Report Share Posted June 8, 2004 I just borrowed an infrared thermometer and found out that I have been pouring at around 290-320 degrees. If I get the plastic up to 350 its too runny and hard to control and curls some colors of the large glitter flakes. I don?t have any shrinking problems except in my alum stick molds when they are really cold. I warm them slightly with a butane torch before I make my first pours and it helps.
