  • Offset flow injection nozzle
    Patent number: 4412807
    Abstract: This relates to an injection nozzle which is provided with a valve gate pin for selectively interrupting plastic flow therethrough. The internal construction of the nozzle is such that the plastic flowing therethrough for injection into an injection mold is uninterrupted and in no way divided so that there will be a separation of the plastic and a rejoining in a manner which will provide for a welded interface. The valve gate pin, notwithstanding the uninterrupted flow passage, is fully supported throughout its length.
