Is there a balanced medium between those two senarios you mentioned?

Steve, did you make your mold with Polyester resins ?
If so....and if there wasn't an added support frame bridge built on the mold backside, its possible your mold is heat cycling and warping as you make parts.
Either that, or you need to add less MEKP % to let the parts fully cure in the mold before de-molding.
Best bet is to post cure the part while still in the mold with heat lamps overnight. THEN de-mold .
