Patent number: 6824379Abstract: Injection molding apparati, systems and methods are provided for limiting forward valve pin movement during flow control. According to one embodiment, an injection molding apparatus is provided that includes an actuator, and a valve pin coupled to the actuator. The valve pin is adapted to open and close a gate to a mold, and to control a rate of material flow through the gate during an injection cycle. The actuator is further adapted to control the valve pin in a first range of movement in which the valve pin is adapted to control the rate of material flow and cannot close the gate, and to control the valve pin in a second range of movement which includes the valve pin closing the gate.Type: GrantFiled: June 20, 2002Date of Patent: November 30, 2004Assignee: Synventive Molding Solutions, Inc.Inventors: Mark Doyle, David Kazmer, Mark Moss, Vito Galati

Patent number: 6769896Abstract: An injection molding apparatus and method are provided in which the rate of material flow during an injection cycle is controlled. According to one preferred embodiment, an injection molding apparatus is provided that includes a manifold, at least one injection nozzle coupled to the manifold, an actuator, and a valve pin adapted to reciprocate through the manifold and the injection nozzle. The valve pin has a first end coupled to the actuator, a second end that closes the gate in a forward position, and a control surface intermediate said first and second ends for adjusting the rate of material flow during an injection cycle. Retracting the valve pin tends to decrease the rate of material flow during the injection cycle and displacing the valve pin toward the gate tends to increase the rate of material flow during the injection cycle.Type: GrantFiled: January 31, 2003Date of Patent: August 3, 2004Assignee: Synventive-Molding Solutions, Inc.Inventors: David Kazmer, Mark D.
