Hello all. I made my first oven-vulcanized mold yesterday, with
disappointing results. I used an aluminum mold frame (borrowed),
two aluminum plates, and three “C” clamps, and pre-cut mold
rubber. The problem was uneven pressure, and maybe too much rubber,
since it oozed out of the sides. The mold is not usable.
I want to get into mold making cheaply. I so far own two cold
mold frames (came in a group of 2nd hand stuff) which I haven’t
With my lack of success yesterday, I was looking in the Rio
catalog and saw a clamping device with 2 platens and a screw on
each end. Has anyone used this? Is this reccommended? Obviously,
I don’t want to buy a vulcanizer, but I need quality, consistancy
and ease of use. Any guidance would be appreciated.
