ABSTRACT:
A two-piece injection molding nozzle seal. The inner piece through which the melt duct extends is formed of a highly thermally conductive material to enhance heat transfer during the thermodynamic cycle. The surrounding outer retaining piece which extends from the heated nozzle into contact with the cooled mold to provide the necessary seal is formed of a substantially less conductive material to avoid undue heat loss.
