When you are making a rubber mold to reproduce an item that can later be
cast in wax, I noticed you have a choice in mediums. One type sets at room
temperature and the other requires vulcanization. I was looking at the
vulcanization machines for sale and it appears they are nothing more than a
vice with a heating element on the end.
Question: Can one achieve the same effect with a mold heated in an oven
while being compressed with metal C clamps? Is it the pressure applied
prior to baking that causes the vulcanization or the pressure created during
baking where the medium can not expand that causes it?
Clueless, any help is appreciated.
