Abstract
A nozzle for an injection molding apparatus includes a nozzle body having a first nozzle body segment, a second nozzle body segment and a third nozzle body segment. The second nozzle body segment is removably connected to at least one of the first nozzle body segment and the third nozzle body segment. The first nozzle body segment and the third nozzle body segment are heated either by first and second nozzle heaters, respectively, or by a heater sleeve having a cut-out along the length of the second nozzle body segment. The second nozzle body segment is substantially devoid of a nozzle heater such that the second nozzle body segment is heated passively through contact with the first nozzle body segment and the third nozzle body segment.
