ABSTRACT OF THE DISCLOSURE This invention relates to a method of providing an injection molding heated nozzle with an improved electrical terminal. A plug is seated in a radial opening in the collar portion with heating element extending through it and the rear end of the heating element projecting a minimum distance from the front surface of the plug. The insulation and casing are stripped from the projecting portion and the exposed resistance wire is welded to a flat surface on a larger diameter threaded conductive stud. A sleeve having a threaded and broached inner surface is mounted over the stud with the outer end of the stud projecting beyond the outer end of the slee The plug and sleeve are integrally brazed in place during the brazing step forming the rest of the nozzle. A liquid ceramic insulating material is poured to fill the space between the stud and the surrounding sleeve. A ceramic insulating washed and a steel washer are mounted on the projecting outer end of the threaded stud, before receiving the electrical lead which is held in place by a nut. The ceramic material bonds to the threads and grooves on the inner surface of the sleeve and to the stud and secures it against the application of lateral and axial forces, as well as torque and considerably reduces failure of the resistance wire.
