Trying to figure out how to keep the bag to stay tight all the way through the infusion process. there’s absolutely no leaks before we start infusing the resin. But as soon as we open up the resin inlet line the inlet side/area of the bag loosens up and it really never get a tight until the resin starts to gel. Anyone have this issue or does anyone know how to fix this issue. I’m finding small pitting on the surface and only on the inlet side so i’m guessing g it’s happening from the bag being loose on that side.

Thanks for the info MarkMK, Yes we do already give it a resin break, but one thing we are doing is clamping off the inlet line first and a minute later clamping off the exit. No resin is traveling down the exit line when we clamp. But I do notice that the small pits we are getting are in the inlet side. So i’m guessing it has to do with the bag being looser on that side? Or maybe since there’s more resin on that side at the time it gassed off differently and shows signs on the surface?
