Abstract
A unitary monolithically formed hot-runner apparatus having at least a manifold containment structure, a hot-runner manifold, at least one nozzle, and one or more spacers. In some embodiments, the manifold containment structure, hot-runner manifold, nozzle(s), and spacer(s) may be multi-material apparatuses of unitary monolithic construction. In other embodiments, a thermal expansion accommodation portion is provided for each nozzle to accommodate thermal growth. Each spacer may be formed of a material having a lower thermal conductivity than the materials of the hot-runner manifold and manifold containment structure and may be made to include a discontinuity to allow for thermal expansion.
