Abstract: An electrically heated nozzle for use in injection molding which is positioned between an injection apparatus and a die casting machine in an injection molding operation. The nozzle transfers molten material such as metal under pressure from the injection apparatus to the die. The nozzle has a refractive core, with a flow passage, surrounded by an intermediate metal core which is heated by a coil of electrical resistance wire to prevent heat loss in the molten metal. A metal sleeve surrounds the coil and the intermediate core. The heating coil is attached to a control box which energizes the coil and controls the temperature.

Abstract: An electrically heated nozzle for use in injection molding is positionable between an injection apparatus and a die in an injection molding operation. The disclosed nozzle is formed in three sections an end cap integrally formed with a sleeve, a housing surrounding the sleeve, and a nozzle tip also surrounding the sleeve forwardly of the housing. A coil of electrical resistance heating wire is wrapped around the sleeve inside the housing. A control box is provided for varying the current flow to the coil heater wire.
