Abstract
An injection molding nozzle having improved corrosion and wear resistance is disclosed for use in a hot runner injection molding system. The nozzle includes a nozzle body having a nozzle melt channel for receiving a melt stream of moldable material from a melt source. The nozzle has a nozzle seal comprised of a tip retainer and a nozzle tip having a tip melt channel, wherein the tip retainer secures the nozzle tip to the nozzle body such that the tip melt channel receives the melt stream from the nozzle melt channel. The nozzle tip further includes a tip base of a thermally conductive material that has a diamond crown secured to a downstream end thereof. The diamond crown sits within a vestige area of the injection molding system and provides improved corrosion and wear resistance to the nozzle tip.
