bradley4bengals Posted March 4, 2008 Report Share Posted March 4, 2008 I made some two part pop swim bait molds and poured some today. They came out pretty good but most of them had air pockets in them and some had holes in them. I would pour them until the plastic would come out of the top. But after it set for awhile it would go down in the mold really slow and I would pour more plastic in the pour hole until it came out again. I think that I have the molds vented well enough. Any suggestions? Thanks guys. Quote Link to comment Share on other sites More sharing options...
Richard Prager Posted March 4, 2008 Report Share Posted March 4, 2008 Sounds like you are not topping them off fast enough thus creating the air pocket. Quote Link to comment Share on other sites More sharing options...

bradley4bengals Posted March 4, 2008 Author Report Share Posted March 4, 2008 thanks guys so you think I need to pour them faster? Quote Link to comment Share on other sites More sharing options...
Richard Prager Posted March 4, 2008 Report Share Posted March 4, 2008 Not so much to pour faster as to top off faster. As one stick fills, go back one and top off. Fill the next stick, then go back and top off. You want to keep a little "mound" showing at all times. When you let the plastic contract and then top off, you are creating an air pocket. You can always remelt your trimmings. Quote Link to comment Share on other sites More sharing options...
nova Posted March 4, 2008 Report Share Posted March 4, 2008 The problem he is having is much more ampilfied than it is with sticks as his baits are a much bigger volumn. As the plastic starts to cool down, it shrinks and sucks into itself from the spru. He will have to more on top of it than someone pouring sticks because it will happen faster and with much more volumn. www.novalures.com Quote Link to comment Share on other sites More sharing options...
bradley4bengals Posted March 5, 2008 Author Report Share Posted March 5, 2008 yeah as soon as the mound started to go in enough for me to pour more plastic I did. Maybe I need to make my pour hole larger. Just a thought. Does anyone else have this same problem or is it just my molds? Thanks again.
