Abstract
A hot-runner system having a manifold and a nozzle, wherein the manifold or nozzle or both may be multi-material apparatuses of unitary construction. The nozzle may be thermally graded for temperature transmission between a heating sleeve and the melt. The nozzle may also include a melt flow channel apparatus that alters the flow of the melt before entering the mold. The nozzle and manifold may have a unitary construction that reduces fitting problems between the two apparatuses.
