Abstract
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.
