Hoping for some help here.  My bagging is basically 50/50 ie one success to one fail. I'm making the bags using both the standard EC bag and the stretchy stuff depending on the part. I try to take a lot of care in making the bag and I feel I'm fairly precise with it but when do the vac drop test the needle will often pop up when I release the clamp.  Try as I can in terms of checking the tape and the bag, it's usually the case in a failure that all the pressing and checking will not find a leak, but there is one there of course.  Is there a device which can find a leak? I have tried everything including smoke to try to find a leak to no avail.

To be fair Fred I don't think you're using our infusion mesh (our infusion mesh has been clear in colour for at least 9 months) and so we need to be careful in this area of the forum that if experiences of products don't relate to our products that we make that clear. Most people would assume you're referring to our mesh and film and although you're a valued customer I can't see that you've ever purchased either.

In my experience our standard bagging film will not be punctured by our standard infusion mesh in normal use. I never say never but we've done a lot of infusions ourselves with this combination.

Kind regards, Matt

Hi Matt

Your right, the mesh I use is a kind of green color and quite thin and it is not your product. My advice was not intended to be product specific but generic. If your mesh is softer that is good to know and I am sorry if your customers get the wrong idea. I was not referring to your product.

But leaking bags are madding, so trying everything possible to eliminate the leaks is what is important, so I advised on every trick in the book that I could find to try and help. ( From my personal experience.)

I have now tried a new product I wonder if you have heard of it. It is an infusion mesh/ release film combined in one. It is from Europe and is a blue color. It is extremely comformable and drapable. It is quite soft and does not puncture my bags. (I could get the name if you like)
