THE NOZZLE WITH A METAL RING OF HOT RUNNER SYSTEM

摘要

The present invention relates to a nozzle with a metal ring of a hot runner system, which comprises: a nozzle body having a shape of a column form with an acuminate form of which diameter becomes smaller on the lower end of the column form, and including a coupling groove on the acuminate form; a flow path axially formed on the nozzle body for the flow of a molten resin, and including an injection hole for injection of the resin to the outside; a heating body formed on the outer surface of the nozzle body to continuously apply heat to the resin inside the flow path; a protrusion part protruding from the upper end of the nozzle body to fix the nozzle body on a plate of the hot runner system; and a metal ring coupled with the coupling groove to minimize the heat conductive rate of the nozzle body.
