squigster Posted February 1, 2008 Report Share Posted February 1, 2008 How do you guys pour two or three colors without getting seperation cracks on the baits? Everytime I try this I get thin crack lines where the different colors meet. ANy help would be appreciated. Quote Link to comment Share on other sites More sharing options...
nova Posted February 1, 2008 Report Share Posted February 1, 2008 You have to get your plastic hot and you have to pour one bait at a time. Each color has to be laid one on top of the other as soon as you can. If you let the layers cool too much you will get cold cracks. Also, you must work with warm molds. I usually pour scrap plastic in the molds prior to starting the baits to warm the molds. You only need to do this once because once you start to pour your baits the molds will stay warmed. www.novalures.com Quote Link to comment Share on other sites More sharing options...
pastorshane Posted February 1, 2008 Report Share Posted February 1, 2008 I haven't tried this yet but some guy's lay their molds on a warm not hot griddle and pour them to keep from getting cold cracks. Quote Link to comment Share on other sites More sharing options...

eugene Posted February 1, 2008 Report Share Posted February 1, 2008 If this is a one peace mold, you can use a hand tourch to (FLASH) over the first pour and it will turn the top of the plastic like glass, then you pour the next color befor it gets cold and it will stick like glue, and no cold cracks. eugene Quote Link to comment Share on other sites More sharing options...
squigster Posted February 1, 2008 Author Report Share Posted February 1, 2008 Heating the mold may help my uneven pouring by keeping the plastic fluid longer. I'll see what happens. I guess it takes practice but my free hand pours on one piece molds almost always come out uneven. It may have to do with the plastic cooling too fast. I tried somethng that did work but was a pain. I covered a one sided POP mold with lexan sparayed with Pam and clamped it to the mold only leaving the nose of the worm open as a pour opening and poured the plastic with the mold at a 45 degree angle. It worked real well except you end up with the overflow plastic that you have to trim off and I guess you are also limited to one color by doing it this way, but the bellys were perfectly flat.
