US Patent 7494336 - Nanocrystalline nozzle tip for injection molding


Injection molding is a process used to form plastic articles. The tip used in the injection requires a high thermal conductivity in order to keep the plastic in a liquid state while it is flowing but allow a quick dissipation of the heat during solidification. This patent from Husky Injection Molding Systems teaches using nanocrystalline material to achieve this goal. Claim 1 reads:

1. An injection molding nozzle for an injection molding runner system, comprising:

a nozzle body; and

a nozzle tip; and

a melt channel extending along a longitudinal axis between the nozzle body and the nozzle tip;

wherein the at least one of the nozzle body and the nozzle tip is made from a nanocrystalline material.
