Abstract
An injection molding apparatus and system are provided in which the rate of material flow during the injection cycle is controlled. According to one preferred embodiment, an injection molding system is provided that includes an injection molding machine including a hydraulic power source, a manifold for distributing material injected from said injection molding machine to a plurality of gates leading to one or more mold cavities, and a controller to individually control respective rates at which material is injected through said gates during an injection cycle. The controller is coupled to the hydraulic power source and the hydraulic power source supplies hydraulic power to both the injection molding machine and to control said respective rates.
