pureactionbaits Posted January 18, 2017 Report Share Posted January 18, 2017 Try holding pressure for 15-20 second after you inject. I had the same problem with the 709 craw and this solved the problem. Quote Link to comment Share on other sites More sharing options...

MonteSS Posted January 19, 2017 Report Share Posted January 19, 2017 Make sure the sprue is always full and you will be fine. Quote Link to comment Share on other sites More sharing options...
pureactionbaits Posted January 19, 2017 Report Share Posted January 19, 2017 I don't keep track. I'm so used to my microwave that I don't even need a infared thermometer anymore. I've injected both hot and cool and the baits turn out good with 15-20 seconds pressure. Also like Monte said keep the spruce full. Quote Link to comment Share on other sites More sharing options...
smallmouthaholic Posted January 19, 2017 Report Share Posted January 19, 2017 I'm sorry to disappoint but holding pressure will not eliminate micro bubbles. I must be doing something wrong as I always rely on an infrared temperature gun to periodically check the temps of my plastisol in the pots w/ stirrers on my Ultra-molds injection system Quote Link to comment Share on other sites More sharing options...
bryanmc Posted January 19, 2017 Report Share Posted January 19, 2017 I've never seen micro bubbles form in a mold, they had to be there from the start. Maybe he's calling something else a micro bubble. Quote Link to comment Share on other sites More sharing options...

hpssports Posted January 19, 2017 Report Share Posted January 19, 2017 Purge your injector before shooting & see what happens. Quote Link to comment Share on other sites More sharing options...
smallmouthaholic Posted January 19, 2017 Report Share Posted January 19, 2017 (edited) They are not micro bubbles.It appears that your injector MAY be drawing air. 1- Make sure your nozzle is submerged in the plastisol as the level of plastisol decreases 2- Check the gaskets inside your injector 3- Draw your plastisol slower 4- Clean and lubricate the inside of your injector often w/ Pam It's funny this subject came up this morning.Set up to make some single color baits and the injector would not draw.I've used this particular injector for years w/out problems. I tried some glass bead media a couple of months ago and low and behold,after close inspection, a piece was missing out of the quad "O" ring on the plunger Edited January 19, 2017 by smallmouthaholic Quote Link to comment Share on other sites More sharing options...
