"Cutting into a Mold" Topic

My friend has low'ish temp (165) rubber and a vulcanizer. He says he needs to use an xacto knife to cut out the original sometimes because it sticks. Is there a way to avoid this since cutting anywhere near my original is unhealthy for my heart to bear. BEER! mmm..

anyways, any suggestions, or is this just the way its done etc?

If a proper release agent is used between both halves of the uncooked rubber I can't see why it would stick.

Most expect masters to be damaged if not destroyed in the vulcanising process (it's just the way it is). If you want to keep the master intact you might be better making a two part cold cure mold, casting off some metal figs, and using the product to make a vulcanised mold.

I understand. I was thinking of sending them out to my buddy first before they are sent for mass production. But, from what everyone is saying it appears my GS originals might get horribly messed up from the mold process, so I might as well send them straight out for masters in china etc. Otherwise I might not have anything to even send out to china! ;) Thanks for the info!

I do not have many original masters damaged using my vulcaniser, unless they are hollow plastic, sometimes the stuck on parts come off but the casts from them get used as the next originals ect.
a good dose of talk powder would stop making things stick though.
good luck
