Big Ray Posted November 4, 2015 Report Share Posted November 4, 2015 (edited) Hey guys I was wondering if there is a way to keep your plastic hot after you warm it up in a microwave. I noticed when I heat up my plastic I get a lot of air bubbles when first warm it up. So I just wait a minute for most of them to just come to the surface and p.o.p. But when I shoot my plastic by the time my plastic is cool and I have to warm it up again. So I have to do the same thing over and wait for the air bubbles to dissipate. I just want to heat it once and keep it warm until I am done using it so it stays liquid. Edited November 4, 2015 by Big Ray Quote Link to comment Share on other sites More sharing options...
Driftwood Posted November 4, 2015 Report Share Posted November 4, 2015 I pour mine in a fry daddy with heat control. I can shoot enough to last for several trips and have extra for some friends. 2 Quote Link to comment Share on other sites More sharing options...
Jig Man Posted November 4, 2015 Report Share Posted November 4, 2015 I use nor por silicone cups and have made insulated jackets that I can put them in to keep them warm longer when I am shooting small baits with only one mold. Quote Link to comment Share on other sites More sharing options...

mark poulson Posted November 4, 2015 Report Share Posted November 4, 2015 I pinch the tops of my Norpro cups shut with large black paper clip, like chip clips, and the plastic stays hot a lot longer. They're the same clips I use to make pour spouts with, by pinching down one side of the cup until it makes a smaller opening. 1 Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted November 4, 2015 Report Share Posted November 4, 2015 Plaster of Paris is a fantastic insulator. So good that you can take it out of a hot oven with your bare hands. I posted the idea of making plaster jackets a long while back. I am not sure if the idea was ever used. Dave Quote Link to comment Share on other sites More sharing options...
mark poulson Posted November 4, 2015 Report Share Posted November 4, 2015 Dave, I can see it working if I'm injecting, or dipping, but not for hand pours. The problem for me with using pop as an insulating jackets for my Norpro cups is that it is rigid, so I can't pinch down the mouth of the cup to make a pour spout. And because the silicone is a pretty good insulator on it's own, I couldn't pinch the cup shut between injections to preserve heat, so I'd be having to reheat more, and longer. Lastly, it would make the cups even heavier and more awkward to handle. I like that I can grip the edge of the silicone cup with my gloved hand, bend it down, and pull it out of the microwave, without fear that I will drop two cups of hot plastisol. 2 Quote Link to comment Share on other sites More sharing options...
JRammit Posted November 4, 2015 Report Share Posted November 4, 2015 The clock on our old coffee pot no longer works, so i can't set the timer to have coffee ready when i wake up... This frustrates me 1 Quote Link to comment Share on other sites More sharing options...
alsworms Posted November 4, 2015 Report Share Posted November 4, 2015 The clock on our old coffee pot no longer works, so i can't set the timer to have coffee ready when i wake up... This frustrates me Why is this relevant? I think i can talk the wife into buying a new one.... And wonder if i scavenge the hot plate off the old one, would it keep my plastic warm enough if i set my anchor cup on it between pours??? I know it's old school, but it worked for me. Transfer from microwave to hot plates always did the job! 1 Quote Link to comment Share on other sites More sharing options...

Jig Man Posted November 5, 2015 Report Share Posted November 5, 2015 My coozies are made of some foam I had. I doubled it and used gaffer tape to seal off the bottom. It allows me to pour or inject since I use the teflon cups. Quote Link to comment Share on other sites More sharing options...

mark poulson Posted November 5, 2015 Report Share Posted November 5, 2015 A hot plate sounds like a good Idea. Ray, Just be sure the plate won't melt you cups. I don't know how hot they can get, or the melting point of Norpro cups. I do known the silicone doesn't transmit heat like glass does, so it may be a wasted effort to put them on a hot plate. Jig Man's insulated cup would probably be more effective, but I've found that just pinching the mouth of the cups closed between pours keeps the plastic temps up enough that I can inject, clean out and relube the injector, open my molds and cut off the sprues, put both the injector plastic and the sprues back in the cup, and only have to reheat for 30 seconds+- to get the plastic hot enough to inject again. I do stir the crap out of it, once it's reheated, to be sure everything is remelted. Nothing spoils an injection like lumpy plastic. 1 Quote Link to comment Share on other sites More sharing options...
Jig Man Posted November 5, 2015 Report Share Posted November 5, 2015 Jig Man, Can you still pinch off the mouth of the cup to make a smaller pour spout? Yes I can Mark. The foam is almost as pliable as the nor por cups. I always pinch the cup when doing open pours on my craws and trailers. Quote Link to comment Share on other sites More sharing options...

I got all my burners at Wally World, and they are very temperamental. NEVER run them on high.......medium works best. 1 Quote Link to comment Share on other sites More sharing options...
Big Ray Posted November 10, 2015 Author Report Share Posted November 10, 2015 Thanks guys I appreciate the advice. I am going to take your advice Mark and clip the cups after I inject. For some reason I just never did that. Quote Link to comment Share on other sites More sharing options...
