That really depends on the resin, Tg requirements, geometry, target cycle times, part thickness, ... Probably best for general use would be to let it gel at ambient temp and then ramp and hold to like 10°C under max Tg of the resin.

I dont like to have my mould at a different temperature to my resin. If you heat the mould, I would heat the resin to the same temp - which you would only do if trying to lower the viscosity and you....

I think having the mould at like 25°C when doing the infusion in a could workshop could be nice I feel. Keeps the vicosity in the infusion low and prevents thermal runaway. But only useful for very.....

I agree it depends on tons of things. Warmer is almost always better as long as you have the open time to fully infuse before things start to gel. For normal epoxy, 30-35C is fine. I am not opposed t...
