  • Large part injection mold apparatus and process
    Patent number: 11865755
    Abstract: A method of performing an injection cycle having a duration comprising: beginning the injection cycle with the valve pins associated with two or more nozzles in a gate closed position, selecting a first one of the two or more nozzles and controllably driving its associated valve pin from the gate closed position to a selected first axial upstream position, upon downstream flow of the injection fluid through a cavity the preselected distance, controllably driving the valve pin associated with the other of the two or more nozzles to a selected second axial position upstream, holding or controllably driving the valve pin associated with the first one of the two or more nozzles in or to one or more reduced flow axial upstream positions that are partially closed.
    Type: Grant
    Filed: October 12, 2022
    Date of Patent: January 9, 2024
    Assignee: Synventive Molding Solutions, Inc.
