Non-naturally balanced feed system for an injection molding apparatus

摘要

A non-naturally balanced feed system for an injection mold of an injection molding apparatus, the injection mold having a plurality of mold cavities, the plurality of mold cavities receiving molten plastic at a substantially constant viscosity, the non-naturally balanced feed system comprising: a hot runner having a first feed channel that terminates at a first mold cavity in the plurality of mold cavities and a second feed channel that terminates at a second mold cavity in the plurality of mold cavities; and a gate for receiving molten plastic, the gate being in fluid communication with one of the first and second feed channels wherein the feed system maintains a balance of 90% or greater.
