Disclosed herein is a method of injection molding at low, substantially constant melt pressures. Embodiments of the disclosed method now make possible a method of injection molding that is more energy&#x2014;and cost&#x2014;effective than conventional high-velocity injection molding processes. Embodiments of the disclosed method surprisingly allow for the filling of a mold cavity at low melt pressure without undesirable premature hardening of the thermoplastic material in the mold cavity and without the need for maintaining a constant temperature or heated mold cavity. Heretofore, it would not have been expected that a constant pressure method could be performed at low pressure without such premature hardening of the thermoplastic material when using an unheated mold cavity or cooled mold cavity.

Method for injection molding at low, substantially constant pressure

An injection mold assembly for a high output consumer product injection molding machine, the injection mold assembly having a simplified cooling system that is an evaporative cooling system or a cooling system including a hazardous, dangerous, or expensive cooling fluid. The simplified cooling system has a cooling fluid channel that is confined to a mold support plate.
