  • Patent number: 11104049
    Abstract: A hot runner nozzle includes a nozzle body, an annular outlet channel in the nozzle body, a source channel upstream of the annular outlet channel in the nozzle body, and a flow transition channel in the nozzle body. The flow transition channel interconnects the source channel with a part-annular segment of the annular outlet channel. The flow transition channel widens in a downstream direction and has a non-uniform cross-sectional channel thickness in either or both of the longitudinal (downstream) and transverse directions. The geometry of the flow transition channel may promote at least one of a uniform velocity profile and a uniform temperature profile in a generated annular or part-annular melt flow.

  • Publication number: 20210069953
    Abstract: An apparatus and method for actuating a valve stem between an open position and a closed position and for taking one or more valve gated nozzle out of service is disclosed. The hot runner includes a valve gated nozzle having a valve stem, the valve stem coupled to a piston that is held against an actuation plate via pressurized air. When a valve stem becomes stuck in a gate of the hot runner, the actuation plate can continue to move while the piston remains stationary. The valve stem may also be protected from an over force situation such as if the valve stem encounters an obstruction as the actuation plate is moving toward the closed position.

  • Patent number: 8801426
    Abstract: A dynamic mixer and associated injection molding system for mixing a melt flow. The injection molding system includes: a hot runner assembly having a plurality of splits; an injection unit that delivers a melt flow to the plurality of splits in the hot runner assembly via a melt channel; and a dynamic mixer incorporated into the melt channel upstream from the plurality of splits, wherein the dynamic mixer includes a rotor assembly configured to be rotationally driven by the melt flow, and wherein the rotor assembly is further configured to mix the melt flow passing through the melt channel.
