Hello everybody,

I am going to make a mould for something shaped like the half of a car door. Usually I would go for the unimould system but now I am thinking of using the tooling prepreg to have the option to use prepreg for the part.

Any advises or ideas/pro/cons?

Thanks!

Yes, any wet-laid moulds will work fine with temporary flanges, doesnt matter what resin you're using.

As soon as you try to pull full vacuum on anything with temporary flanges, it will warp and pull the flanges off the part. If you're using a material like coreflute for your flanges then this will crush under the vacuum pressure.
