Bass4Me Posted August 20, 2012 Report Share Posted August 20, 2012 Hello everyone. I know this is an old subject, BUT!!!!! It's also the reason I'm posting it. I've been reading older posts about pop molds and the problems occured from them. There was 1 common fact that no one mentioned in them when someone had problems getting full pours. I'm no expert and to this day..... I've only poured a few baits for my friend while at his business. I could be wrong and I'm willing to stick my head out if I am. One thing with metal molds is to keep them warm while pouring, This allows the plastic to remain hot and not cool too fast from contacting the inside of the molds,which creates pours with dents, hollow areas or incomplete pours. When pop mold problems occured, No one said anything about the mold being cool before pouring the plastic. I was just wondering is there is a way to warm up the pop mold and not waste plastic and so plastic will properly fill the mold and not cool to quickly. I'm sure this is why pours went from bad to acceptale as they poured more baits in 1 sitting. Seems 2 + 2 was never put together to make 4, lol Quote Link to comment Share on other sites More sharing options...
EdL Posted August 20, 2012 Report Share Posted August 20, 2012 I don't do any pouring so I don't have any experience. BUT how about one of those food warming trays. Put the POP molds on them, plug the warmer in and let it slowly heat the molds. Like I said just an idea to warm up the molds. I thought about microwaving them but the mold may not have enough moisture in it and a quick heat might cause the mold to fail after a few cycles of heat, cool down, heat, cool down. Maybe somebody has already figured this out. Quote Link to comment Share on other sites More sharing options...
nova Posted August 20, 2012 Report Share Posted August 20, 2012 All I do is melt down some scrap plastic and pour it into the molds; leave it there while you are preparing the plastic formula that you are going to pour. That will pre-heat your molds for you. www.novalures.com Quote Link to comment Share on other sites More sharing options...
mark poulson Posted August 20, 2012 Report Share Posted August 20, 2012 You can try hitting the mold with your hair dryer while the plastic is warming. Quote Link to comment Share on other sites More sharing options...

mark poulson Posted November 28, 2012 Report Share Posted November 28, 2012 Just remember POP turns back into powder if it gets too hot for too long. I've been pouring with some POP molds sealed with epoxy for years now, and not had any breakdown, but I know it's possible. Quote Link to comment Share on other sites More sharing options...
nova Posted November 28, 2012 Report Share Posted November 28, 2012 Me too Mark. I've got some POP molds that are pushing 20 years old and still fine. Quote Link to comment Share on other sites More sharing options...
