- how to get a mold unstuck from the mold frame. When you vulcanize a 0% shrinkage mold in an aluminum mold frame it might be hard to get the mold out of the frame. Mold Materials that shrink, even a little, shrink away from the sides of the mold frame. This allows you to push the mold out of the frame with your fingers.
I show how to use your vulcanizer, a larger mold frame and a smaller piece of aluminum or wood to push the vulcanized mold out of the frame.
Hi Mr Hunner. I am a big fan and want to absorb your knowledge of mold cutting. I have been making jewelry since the early 80's but just started to make molds with RTV Castaldo LiquiFast Ice. I am in awe of your video about using film containers but the only thing missing from that video was cutting the vents for the head that RIO made. Im real curious on how you would cut vents for a cylindrical mold. That and all you share is very valuable information I cant get enough of. Thank you Sir.
Hi Mr Rez, Thanks for your kind words and eagerness to learn. The film containers are only a way save mold compound when you are short on materials. I find that flat rectangular molds inject much more predictably. The greater surface area of the flat molds allow slightly higher wax injection pressures to fill the mold more quickly and accurately. I cut the vents to the edge of the film canister mold in the same manner that I'd cut vents in a flat mold.
Thanks sirji
Glad you found value here.
Any other ideas on ways to remove a silicone mold if you don’t have that larger frame and aluminum insert?
Hi Tina, Thanks for your excellent question! You can use two pieces of board, maybe 1x2 by 4 inches long. Place one piece under the mold frame with the stuck mold in it. Place each board under the right end and the left end. Then, take a smaller piece of wood, almost but not quite the size of your stuck mold. Center that piece of wood on top of the mold taking care not to touch the top of the mold frame with that piece of wood. Tighten the platens of the vulcanizer to squeeze the mold through the frame. Next time, spray the inside of your mold frame with teflon spray available at any auto parts store. Please tell me how this works for you. Thanks!
@@chuckhunner I’m a little concerned about using Teflon as it is a carcinogen. I tried using the paper backing yesterday on the inside of my 1” frame yesterday it worked amazingly well. I’m using LTV. I had less trouble with my smaller frames but I really appreciate your videos and advice! I’ll try the wood options next time I’m stuck.

Perfect Tina. Glad you're finding solutions
Thanks again for your interest in my craft.
