Mongo Posted March 11 Share Posted March 11 I saw a video where a company uses a system to create reusable rubber(?) vacuum bags. I was wondering, at what usage do these systems make sense? Will I need to use it to make 25 copies of 1 part before I start to see the benefit? 50 copies? 100? Quote Link to comment Share on other sites More sharing options...

Do you have a link to the video you're referring to? Quote Link to comment Share on other sites More sharing options...
Adam Posted March 28 Share Posted March 28 @Mongo I don't know the price for these reusable rubber bladders, but I can tell you that vacuum bags can be difficult to get right. With time and practice, like anything, you get better at it, but it takes some getting used to. Quote Link to comment Share on other sites More sharing options...

I've used this material to make reusable bags before. It's pretty easy and cheap to do by hand, no special equipment. The trick is one light brush coat before building up thickness (to avoid bubbles). https://www.reynoldsam.com/product/ez-brush/ Quote Link to comment Share on other sites More sharing options...
Jeremy Senne Posted June 3 Share Posted June 3 General comment on this. If you or your team are experienced in vacuum bagging with typical release film/breather/vacuum bag/sealant tape materials you will probably need to be in the 10+ quantity range before you see a benefit. It is worth noting that this is also very ply count dependent. If your ply count is low, this really only helps you with final bag. If your ply count is high (30+) and you have a lot of debulk steps this can significantly cut down on the disposable material use and time to bag. Most places that I've worked have had some sort of quick debulk setup for flat plates as this shows a ROI quickly. Quote Link to comment Share on other sites More sharing options...
