  • Injection molding flow control apparatus and method
    Patent number: 9005509
    Abstract: An apparatus for controlling the rate of flow of mold material to a mold cavity, including a valve system in fluid communication with an actuator to drive the actuator at one or more rates of travel, the valve system having a start position, one or more intermediate drive rate positions and a high drive rate position, the start position holding the valve pin in a gate closed position; a controller that instructs the valve system to move from the start position to the one or more intermediate drive rate positions and to remain in the one or more intermediate drive rate positions for one or more corresponding predetermined amounts of time and further drives the valve system to move from the one or more intermediate drive rate positions to the high drive rate position on expiration of the one or more predetermined amounts of time.
    Type: Grant

  • INJECTION MOLDING FLOW CONTROL APPARATUS AND METHOD
    Publication number: 20120248644
    Abstract: An apparatus for controlling the rate of flow to a mold cavity including a controller instructing a valve system to drive an actuator and a valve pin and including instructions that instruct the valve system to drive an actuator and a valve pin and including instructions that instruct the valve system to move from a start position to one or more intermediate drive rate positions and subsequently from the one or more intermediate drive rate positions to a high drive rate position on receipt by the controller of a signal from a position sensor that is indicative of the valve pin having reached a second position.
