Eol2014 Posted February 14, 2018 Report Share Posted February 14, 2018 Need help..This is going to sound stupid but I cant figure it out. i am getting a small air pocket where the splines join the body on tubes. I am as careful as possible about air in plastic, Ive shot at different temps 360F -325F., shot a different speeds. Im using DO-IT mold and regular plastisol. To make this odd is in the past with different colors this hasn't occured.... Any Idea's. Thanks Quote Link to comment Share on other sites More sharing options...
rynesgto Posted February 14, 2018 Report Share Posted February 14, 2018 any pics? Quote Link to comment Share on other sites More sharing options...
mark poulson Posted February 14, 2018 Report Share Posted February 14, 2018 Check the venting at the end of the skirts. Air bubbles are trapped air that can't vent out. Quote Link to comment Share on other sites More sharing options...
Eol2014 Posted February 14, 2018 Author Report Share Posted February 14, 2018 Mark....not sure what mean about venting. The mold is free of any debris Quote Link to comment Share on other sites More sharing options...
Eol2014 Posted February 14, 2018 Author Report Share Posted February 14, 2018 And just to add more head scratching while the bubble is the same location of the tube, its doesnt occur in the same place in the mold.....idk maybe just a bad nite in the shop.

Fishermanbt Posted February 15, 2018 Report Share Posted February 15, 2018 Is bubbling always around where the skirt starts? If you haven’t already done so give the mold a good scrub with Dawn soap and and a brush. Also check to see that the insert is screwed in tight. Looking at your picture it would appear that your getting venting since I can see the little nub on top of the bait. Quote Link to comment Share on other sites More sharing options...
Eol2014 Posted February 15, 2018 Author Report Share Posted February 15, 2018 Yes bubble is always where body meets the skirt. What is venting and how do you prevent it? Quote Link to comment Share on other sites More sharing options...
mark poulson Posted February 15, 2018 Report Share Posted February 15, 2018 (edited) Do you hold pressure when you inject? I have had to scratch vent lines into the ends of thin details to get them to fill, but your skirt looks like it's filling fine. If that little nib is where you have a vent in the mold, maybe air is being sucked back into the vent as the plastic cools.
