ABSTRACT:
An injection molding apparatus includes a manifold defining a manifold channel for receiving pressurized molding material from an upstream source and a nozzle defining a nozzle channel in communication with the manifold channel to define a flow channel. The nozzle is associated with a mold gate of a mold cavity and delivers molding material to the mold gate. A vane, such as that of an impeller or screw, is rotatably disposed in the flow channel upstream of a mold gate. A motor is coupled to the vane and rotates the vane in either direction. Rotation of the impeller or screw can be automatically adjusted by a controller and a sensor that measures pressure, temperature, or other property of the molding material.
