| 1. An injection molding apparatus comprising:
a manifold having a manifold channel;
a nozzle having a nozzle body including an upstream nozzle body segment having an upstream melt channel, an intermediate nozzle
body segment having an intermediate melt channel, and a downstream nozzle body segment having a downstream melt channel, said
intermediate nozzle body segment disposed between said upstream nozzle body segment and said downstream nozzle body segment
such that said upstream melt channel, intermediate melt channel and downstream melt channel collectively define a nozzle channel
in fluid communication with said manifold channel; and
means for connecting said intermediate nozzle body segment with said downstream nozzle body segment such that said intermediate
nozzle body segment is not movable relative to said downstream nozzle body segment, wherein said upstream and downstream nozzle
body segments are heated and said intermediate nozzle body segment is substantially devoid of a nozzle heater.
