Abstract
The present invention is a nozzle for an injection molding runner system where parts of the nozzle, and in particular the nozzle tip are made from a nanocrystalline material. Nanocrystalline materials used include nanocrystalline copper and nanocrystalline nickel, which have high thermal conductivity and increased material strength. A conventional form of the metal is worked till its grains are reduced in size to less than 100 nm to achieve the desired properties.
