  • Apparatus and method for heating a side gate nozzle
    Patent number: 11254039
    Abstract: An injection molding machine includes an edge gate nozzle with a nozzle body having a primary melt channel and a nozzle head having first and second secondary melt channels that feed melt to first and second nozzle tips. First and second heaters are disposed in the nozzle head to provide heat to the secondary melt channels. In some embodiments, the heaters are positioned adjacent to the secondary melt channels, with first heater is closer to the first secondary melt channel than to the second secondary melt channel. In some embodiments, the heaters are positioned adjacent to the nozzle tips, with the first heater closer to the first nozzle tip than to the second nozzle tip. In some embodiments, each heater is adjacent to both the respective nozzle tip and secondary melt channel. In some embodiments, each heater is individually controllable.
