Patent abstract
A series of injection molding nozzle tips having a novel inner insert. The novel inner insert in accordance with the embodiments of the present invention includes a finned profile having flow channels between the finned sections. The finned profile and its associated flow channels cause the flow of molten plastic in the nozzle to go through a breakup into the flow channels before it is merged at the nozzle flow exit. This breaking up of the molten plastic flow and its merging insures a better mixing of the molten plastic and also reduces stresses within the molded part.
