Nozzle assembly for injection molding apparatus

A nozzle assembly for use with injection molding apparatus comprising an outer sleeve having a relatively large bore extending from an open rearward end forwardly to a substantially closed, tapered forward end having an injection orifice therein;

• an inner nozzle tip having a nozzle bore, and including an annular radial flange seated on an annular shoulder formed within said tapered end of said sleeve, a mounting portion extending rearwardly of said flange, and a forward tip portion extending forwardly of said flange, said forward tip portion having a plurality of flow orifices communicating with said nozzle bore and located upstream of, and in communication with, said injection orifice;
• a manifold insert located within said outer sleeve and including a through bore in axial alignment with said nozzle bore, said manifold insert having a forward end which receives said mounting portion of said nozzle tip and which abuts said radial flange;
• and a coil heater located radially between said manifold insert and said outer sleeve, a forward end of said coil heater seated on said annular radial flange.
