If you are having leak issues it may be better for you to envelope bag the part,make sure you have no sharp elements to the reverse side of the mould as this may puncture the bag and you can cover the reverse side in breather fabric.

Hello Im an apprentice aircraft structures technician and i work mainly with composites my company has started building carbon parts and i am running into difficulties with losing vacuum while resin infusing it seems that either my vacuum bag is blowing out or the vacuum is being cut of by the resin flow. Any pointers or helpful tips and tricks to avoid these issues would be much appreciated.

I'm havin trouble with my first infusion where iv got a tiny air leak sumwhere and I can't find it.
Iv even ripped the bag off it and started again making sure to be carefull sticking it dwn to the gum but still the same
my question is
Is there a certain way to not get leaks or should I just get a ultra sonic detector
Thanks
Forget the detector. I was in your position once and thought a perfectly sealed bag was not possible.
I never have leaks anymore, I infuse, clamp off the lines and cut the vacuum and feed lines off. ( of course after the clamps) and then put the works in my oven.
I went into great detail how to do it somewhere on this site. Read it over and follow the basic rules I follow and your leaks will be a thing of the past.

An ultra sonic detector is the best option.. Vac innovation do a good one. Dont get the ones they sell for car mechanics as it is not sensitive enough. BUT it can still be impossible to find some leaks.. The air tracks along creases or you just cannot find it.. But it is still worth having one if you lose a bag once in a while it happens but it gives you the best chance of fixing a leak.
