A valve gate injection nozzle includes a valve stem for guiding molten resin to a molding area. The valve stem includes an input area for receiving the molten resin, a central area following the input area for processing the molten resin and an output area following the central area for connection of the nozzle with the molding area. The cen tral area includes a first zone for splitting the molten resin into a plurality of streams, a s econd zone for mixing and homogenizing the molten resin, and a third zone for combing the pluralit y of streams and forming recombined molten resin for subsequent direction in a homogenized st ate to the output area. The nozzle further includes a nozzle body portion for enclosing the valve stem, wherein the nozzle body portion preferably includes means for heating the re sin. An injection molding system incorporating this nozzle as well as a method for homogenizin g molten resin are also disclosed.
