Building 1 time use mold. input?

Strick,
Where do you get the hardboard you are talking about. I bought Melamine board 5/8 in which is particle board with a plastic white coating on each side. Its very hard and smooth and I plan on using it for the inside top of the mold and bottom. I've been reffering to it in the posts as plywood but it is called Melamine at Home Depot. The type of stuff you would make cabinet shelves out of. I didn't see anything that would make a rounded 90 degree bend. If there is a board that will make the bend without breaking I'll use it. Let Me know.
Thanks Dave.
