Abstract:
A pressure resistant drop tip nozzle assembly for an injection molding machine having a nozzle body with a nozzle passage extending axially through said nozzle body between a nozzle inlet and a nozzle outlet. The assembly includes a drop tip which has a body connected to the nozzle outlet of said nozzle body. The drop tip has a drop tip bore extending between a drop inlet located adjacent said nozzle outlet body and a drop outlet. A tapered drop passage located at said drop outlet defines a resin flow aperture where resin leaves said drop tip. An internal heating insert is positioned within said drop tip bore. The drop tip body is connected to the nozzle body via a mechanical connection such as screw threads. A reinforcing weld preferably via a continuous laser weld is provided between said drop tip body and said nozzle body.
