  • Publication number: 20250100197
    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.

  • Patent number: 12257750
    Abstract: A molded article suitable for subsequent blow-molding into a final-shaped container. The article includes a neck portion; a gate portion; and a body portion extending between the neck portion and the gate portion, at least a majority of the body portion having an overall shape which is symmetric about a body axis extending longitudinally through a center of the body portion. The body portion includes an inner exterior layer and an outer exterior layer of a first polymeric material; and a core layer of a second polymeric material disposed between the inner exterior layer and the outer exterior layer. A radial thickness or a material of the core layer is selectively varied to govern non-uniform blow molding of the molded article into the final-shaped container.

  • Patent number: 12257749
    Abstract: In one aspect, an injection unit for an injection molding machine having a hot runner with a sprue comprises a heated melt pipe configured to convey a continuous stream of melt, a shooting pot assembly, and a telescopic melt coupling. The shooting pot assembly is configured to convert the continuous stream of melt from the heated melt pipe into batches for cyclical injection and is translatable between a sprue-engagement position and a sprue-disengagement position. The telescopic melt coupling is configured to convey melt from the heated melt pipe to the shooting pot assembly and has a variable length. The variable length telescopic melt coupling permits translation of the shooting pot assembly, relative to the heated melt pipe, between the sprue-engagement position and the sprue-disengagement position while maintaining a fluid melt interconnection between the heated melt pipe and the shooting pot assembly.
