I'd second silicone rubber . You can get high temperature versions but many standard type are probably OK at 100 C. Semi random thoughts: - Somewhat lower temperature for longer would presumably work as well. - Can you mold release early on when the epoxy has attained its basic strength and can be handled reasonably well without deforming - and then place them on a flat sheet - eg Teflon cooking sheet - to final cure. Early release may or may not help releasability. It would allow a dearer mold material to be used to make more parts. - Cure temperature and time sounds like 24 hour epoxy. Can you use a faster setting epoxy. This usually has less bonding strength, but is that an issue here? - Might some mold release spray be acceptable. Not all would be. Silicone s= pray?
