Patent ID: 7695271

Claim:
A nozzle tip, comprising: a nozzle tip body; a nozzle tip inlet end for ingress of a molten resin; a nozzle tip outlet end for egress of the molten resin; a nozzle tip melt channel, located axially therethrough; and a tip insert, distally attached to the nozzle tip body at the nozzle tip outlet end, wherein the tip insert has a thermal conductivity value of K<10 W/m ° K, the tip insert is installed at the apex of the nozzle tip outlet end, and the tip insert is positioned flush with the mold parting line, wherein in steady state, the molten resin will freeze, or solidify, over time since the tip insert sufficiently blocks the conduction of heat to a gate orifice from the rest of the nozzle tip body, and a solidified resin at the gate orifice will not induce a string nor a vestige since the tip insert is positioned flush with the mold parting line.
