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.
