  • Injection molding nozzle
    Patent number: 6609902
    Abstract: A nozzle for an injection molding runner system comprises a nozzle housing having a melt channel through it, a nozzle tip having a tip channel and at least one outlet aperture in communication with the tip channel, and a tip retainer that retains the nozzle tip against the nozzle housing such that the tip channel communicates with the melt channel. The tip retainer is significantly more thermally conductive than the nozzle tip. A nozzle seal that is significantly less thermally conductive than the tip retainer may be fused with the tip retainer, and may be annularly spaced from the nozzle tip.

  • Injection nozzle insulator assembly
    Patent number: 6533571
    Abstract: An injection molding nozzle having a nozzle tip insulator assembly affixed thereon comprised of an inner sleeve and an outer sleeve is disclosed. The inner sleeve is preferably made from a metal with relatively low thermal conductivity and the outer sleeve is preferably made from a compressible non-metal material that can withstand typical injection pressures and temperatures.

  • Hot tip insulator retainer
    Patent number: 6315549
    Abstract: An injection molding nozzle tip thermal insulator includes an apparatus for removably fastening the insulator to a nozzle tip having a receiving detent therein. The apparatus includes a fastening structure that engages the nozzle tip receiving detent and holds the insulator onto the nozzle tip. The fastening structure is movable between a first position where the insulator is fastened to the nozzle tip, and a second position where the insulator is removable from the nozzle tip. Also included are a method of removably attaching the insulator to the nozzle tip, and assembly and removal tools for attaching and removing the insulator from the nozzle tip, respectively.
