My bulb mold is having some problems. The top part got stuck in the main tube, and the aluminum oxide seems to have caused the jamming. Is there a good way to get it out? Link to the bulb mold

Bump!

Have you tried heating the main tube, it might expand enough to increase the clearance and allow removal. I don't know if it will work in this case but I done it a bunch of times with cars, from separating exhaust pipes to removing wheel bearings, a little (or a lot!) of heat goes a long way !

I tried chilling down the inner part with some upside-down compressed air, but it didn't help. I could try spraying the stuck part with a pressure washer or use some pliers to twist it apart. Any other ideas?

Push!

Force! Any ideas?

Explode! I'll post this until I get an answer.

Breaking news! I figured out how to get the mold apart (by using the hydraulic press as a vice and rotating the assembly with big pliers)
Bad news! I now have to make a rubber mold instead of a steel one, so now I need a good way to do that.
