A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater and an insert. The nozzle body defines a first melt channel therein. The first melt channel is adapted to be downstream from and in fluid communication with a melt source. The nozzle body has a downstream nozzle body end. The nozzle body is made from a nozzle body material. The heater is thermally connected to the nozzle body. The insert is positioned in the nozzle body. The insert is made of an insert material. The insert material is more thermally conductive than the nozzle body material. The insert is adapted to conduct heat from the heater towards the downstream nozzle body end.
