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.

Abstract: An injection molding machine comprises a manifold plate, a nozzle extending through the manifold plate, and a gate pad. A valve stem is disposed within the nozzle and is movable between a first position in which the valve stem extends through an outlet of the nozzle, and a retracted position. The gate pad has an inlet end with an inlet opening and an outlet end with a gate aperture. The inlet end is removably attachable to the manifold plate so that the nozzle is received through the inlet opening and the outlet of the nozzle is in communication with the gate aperture, wherein the valve stem seals the gate aperture in the extended position. The outlet end of the gate pad abuts a mold insert and molding material is delivered from the nozzle to a cavity defined by the mold insert through the gate aperture.
