So Post Curing is recommended to be done in the mold? Also, what is the minimum temperature post curing can occur? As the mold is made of polyester resin and glass and I don’t think that the the mold can take more then 60 - 65 degrees centigrade.
You can also do a freestanding postcure. Just take into account the temperature ramp, which should be very conservative.
Ramp should be 10C/h at max, until you reached 60 degrees C, then keep it there for 12-18 hours.
How I know? I read the datasheet!
