Do you still need to heat the HDPE like you do for silicone to prevent moisture build up?

I always warm up my molds. To help with moisture and to help it flow evenly, at least in my mind. I put the tubes in the mold and put all of them in the oven for 10 minutes or so. I also warm my urethane resin before mixing and pouring.
