A pressure compensating molding system with die faces of thin sheets. A thin die sheet separates a mold cavity from a heating/cooling cavity. A heating system causes a heated fluid to flow through the heating/cooling cavity, thereby preheating the thin sheet. The injection material is forced through a sprue into the mold cavity. Pressure sensors monitor the pressure of the injection material in the mold cavity and in the heating/cooling cavity. A controller varies the pressure in the heating/cooling cavity to equalize a pressure differential across the thin die sheet. A cooling system causes a cooling fluid to flow through the heating/cooling cavity to cool the molded component.
