Impossable To Bag

I HAVE A QUESTION ON RESIN INFUSSION,THE MOULD HAS MANY COMPLEX CORNERS AND CURVES AND SEEMS ALMOST IMPOSSABLE TO BAG SOME OF THE CORNERS, I WAS WONDERING IF I USED A HEVEY GAUGE POLY AND USE A HEAT GUN OR MAYBE A HAIR DRYER TO MOULD THE PLASTIC AROUND ,APPLY SOME VACCUM AND THEN HEAT AND DO THIS TILL THE PLASTIC PULLS IN TO THE MOULD HAS ANYONE HAD SUCCESS WITH THIS THE PART IS FAR TO HARD TO FOLD AND PLEAT THE BAG

 

I have never seen plastic stretched by heating used as a vacuum bag.For complex shapes that are intended for production in large quantities would it be worth investing in a tailored silicone bag?

 

If it is a sandwich part you can make foam filler pieces for the corners.

 

hi,
try this stretchlon 200 www.fiberglasssupply.com/Product_Catalog/Vacuum_Bagging/vacuum_bagging.html

You can actually cut your bag and gipe pieces of bag together using a sealant like 3m 5200 or even butyl tape.

 

Never had that problem ,Jack Just use a very wide piece of bag film and stuff it in there ,so what about the pleats and wrinkles.debulk the bag very slowly and watch for any pulling.

 

Im adverse to anything remotely near cutting my bag

 

Iam going to try strechlon film got some delivered on friday i used regular poly but it didnt have enough strech in it.Going to give it a try monday,the part is a mount for a film light and was designed knowing it would be difficult to vaccum, if the strechlon doesnt work going to use a silacone bag they have a product called brush bag , thanks again guys
