reusable cookable vacbags?

[riff42]

Anyone know anything about this subject? Not that I doubt my chief eng, but there has to be some sort of cookable vac bag. There HAS to be an easier way to do a part, vs. layup, debulk, layup again/cure#1, layup, debulk, cure final part (as per what we do.)
and each time, takes the normal, layup, put peelply or solid teflon sheeting over it, taping it to the edge, and then bagging it, which I just can’t get ahang of yet. and that is just debulking, I have to redo it and rebag it for cure!!!

There has to be SOMETHING where I can just put it in the bag, and ziplock it up! eh.

Try checking out www.bondlineproducts.com or / also www.actr.com for a spray on vacuum bagging and reusable system and there was another one from Sampe but it escapes me right now.

I know now: www.torrtech.com

And please, mention this forum to them as where you read about them!

I have not personally done this but watchced it being done once.
The mold had a round groove in a wide flange that surrounded it. They made another flange that bolted down to that flange it had mating groove in it. They used a silicone and spread it all over the mold and flange(top flange removed). once it was tacky they layed a ply of “angel hair” surface veil onto the silicone and troweled on another coat.
They used this bag to infuse multiple hoods with per, they would lay out the mat, then the bag, blot down the sael and pull the vacuum and infuse. They told me they get several months per bag.
It was all a big secret a few years ago so don’t tell anyone I told ya OK

I’ve heard rumors that sprayon bags are horrible, and even the ppl that make them don’t like it!

hmm, sounds like a good idea. I’ll have to run that by my engineers. I’m sure they will say it’s not a good idea, since THEY aren’t doing the work, I am!

At the IBEX trade show I saw that Airtech has a brush-on silicone bagging kit to get beginners started making there own reusable bags.

They have a half round tube that goes around the the edge of the mold and is embedded inside the silicone bag. Once the bag is in place, you use your vacuum to pull the air out of the tube creating a vacuum seal around the edge and eliminating the need for tape.
