Multi-Property Injection Molding Nozzle

摘要

Injection-molding nozzles having any one or more of improved heat transfer, wear resistance, and melt transfer from a manifold to a mold. The operation and durability of a nozzle can be improved by integrally layering multiple materials to create a multi-property nozzle that is a unitary, monolithic, and seamless structure. For example, the heat transfer properties of a nozzle is improved by integrally layering certain materials in the nozzle housing such that heat is more effectively dissipated or transferred throughout the nozzle to maintain and promote melt flow. One or more components of the nozzle can be merged and thus seamlessly formed to improve melt flow by reducing joints that would cause the melt to hang up within the nozzle and, concomitantly, reducing manufacturing and assembly time. The process used to unitarily form some or all of the nozzle may also be used to create complex geometric configurations therein.

1. An injection molding nozzle assembly comprising:
a first nozzle component; a first material having a first characteristic, wherein said first material forms a first portion of said first nozzle component; and a second material having a second characteristic, wherein said second material forms a second portion said first nozzle component, wherein said first material and said second material are integrally fused together so as to form a unitary structure.
