Abstract: Systems and methods for controlling the closing speed of valve gated nozzles are disclosed. In one embodiment, a hot runner have a valve gated nozzle including a valve stem movable between an open position and a closed position is provided. The valve stem is moved at a first speed for a first portion of valve stem closure and a second speed for a second end portion of the valve stem closure.

Abstract: A co-injection hot runner nozzle comprises an inner melt flow channel and an annular outer melt flow channel that surrounds the inner melt flow channel. The inner and outer melt flow channels have a first common source. The nozzle further comprises an annular intermediate melt flow channel disposed between the inner and outer melt flow channels. The annular intermediate melt flow channel is at least partly defined by a plurality of spiral grooves, each spiral groove having a respective inlet and defining a helical flow path. Lands between adjacent spiral grooves increase in clearance in a downstream direction. An annular axial flow path is defined over the lands. A plurality of feeder channels having a second common source is configured to supply melt to the plurality of inlets of the spiral grooves. The relationship of feeder channels to spiral grooves may be one-to-one. The inlets may be longitudinal channels.
