  • FAST ACTING REDUCED VELOCITY PIN CONTROL
    Publication number: 20170305050
    Abstract: Apparatus and method for performing an injection molding cycle using the apparatus where the apparatus comprises: a manifold, a pneumatic actuator driven by a pneumatic valve assembly, the actuator driving a valve pin between a gate closed position and a maximum injection fluid flow position, the pneumatic valve assembly having a spool supported within a cylinder driven by a drive device that is supported solely by and translates together with the spool, a controller that instructs the pneumatic valve assembly to cause the actuator to drive the valve pin either upstream or downstream to selected positions or at selected velocities during the course of a single injection cycle based on a feedback signal indicative of position of the pin or actuator or pressure of an injection fluid material.
    Type: Application
