Abstract

A nozzle for an injection molding apparatus is provided. The injection molding apparatus has a mold component that defines a mold cavity and a gate into the mold cavity. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece and a mold component contacting piece. The nozzle body defines a nozzle body melt passage therethrough, that is adapted to receive melt from a melt source. The heater is thermally connected to the nozzle body for heating melt in the nozzle body. The tip defines a tip melt passage therethrough, that is downstream from the nozzle body melt passage, and that is adapted to be upstream from the gate. The tip surrounding piece is removably connected with respect to said nozzle body. The mold component contacting piece is connected with respect to the nozzle body. The material of the mold component contacting piece has a thermal conductivity that is less than at least one of the thermal conductivity of the material of the tip and the thermal conductivity of the material of the tip surrounding piece.
