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 have a long pot life.
If it is cold where you are working (ie, under 18°C), warm both the mould and the resin to 25-30°, infuse, and then keep the resin and mould at that temperature for at least 18 hours. Then ramp the temperature up if you want to do a post cure.
Gotta ask, if you have an aluminium mould you can heat, why not use pre-preg?
