Patent ID: 7458803

Claim:
A composite material component for an injection molding assembly, comprises: a first portion formed of a precipitation hardened, high thermal conductivity material; and a second portion formed of a precipitation hardened, high strength material, wherein: the high thermal conductivity material and the high strength material are integrally joined together, the thermal conductivity of the high thermal conductivity material is greater than the thermal conductivity of the high strength material, at least one strength aspect of the high strength material has a value greater than the corresponding value of the same strength aspect of the high thermal conductivity material; and the high thermal conductivity material in an unhardened condition and the high strength material in an unhardened condition are precipitation hardenable together under the same precipitation hardening conditions to achieve: an increase in the value of at least one strength aspect of the high thermal conductivity material relative to the unhardened condition, and an increase in the value of at least one strength aspect of the high strength material relative to the unhardened condition wherein the component is selected from the group consisting of an injection molding nozzle tip, injection molding nozzle tip retainer, injection molding retainer plate, injection molding sprue bushing, injection molding manifold bushing, injection molding nozzle housing, injection molding gate insert, injection molding mold cavity insert, and an injection molding core insert.
