processing over gas assistance. Water possesses a thermal conductivity and heat capacity vastly superior to nitrogen gas. Direct contact between cold water and the internal polymer wall extracts thermal energy rapidly from both sides of the part wall. Cooling times drop by up to 70% compared to solid injection molding, drastically reducing overall cycle duration for thick structural parts.
