Will this work inside a vacuum press? If so, it pretty much eliminates costly forms,and can be formed in infinite radi's, to a certain degree of course.

http://www.easy-form.co.uk/index.html

What caught my eye was the form below the aluminum, it appears top just be two radius pieces of plywood attached to strips as opposed to making a whole form. You wouldn't need two aluminum forms as the vacuum press bag acts like the clamp.

For lack of a better term there flexible "platens".

Craig,

Interesting stuff. Where do you come across these things?

I still think you need more ribs that just two otherwise the platen will implode into the empty space but you could definitely get away with fewer of them. I think the big advantage is you dont need to nail down two layers of bending ply that basically cant be reused. I also wonder if you would get slight faceting if you only use one layer of the stuff with the bag on top. If you put another layer on top I'm assuming this would not happen.

The other thing that strikes me is when you go to put on the veneer, the back side veneer between the form and panel, I cant see having the veneer directly against the aluminum will work. A piece of 1/8" bending ply would be a must.

If you get some to play with let us know how it goes.

This stuff just hit the market, it's so new they changed the name already to "Curvomatic". Attached is the price list.


Clearly from the demo photo's He didn't use urea as the piece shows a lot of spring back.

As for my other question, silicone is thicker than poly?

Craig,

Yes, I noticed the spring back as well.

Silicone is rather puncture sensitive so to compensate for that it is usually made two to three times thicker than polyurethane membranes
