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.

Abstract: The invention relates to a molten material processing device having an elongated thermal element like a heating element, a thermocouple, a sensor, a heatpipe and a cooling pipe which is characterized in that the elongated thermal element is located in a recess provided in a surface of the molten material processing device, the recess, including a first portion and a second portion, has a cross-section which is larger than a cross-section of the thermal element, so as to provide a clear space between the thermal element and the surface of the processing device, the clear space which is limited by the first portion and the thermal element is filled by a thermally sprayed material and the second portion, which is adapted to the cross-section of the thermal element, partially surrounds and directly contacts same.
