  • Multi-property injection molding nozzle for a hot-runner system
    Patent number: 8740598
    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.

  • Selective Positioning of Nozzle Tip Relative to Mold-Side of Runner System
    Publication number: 20140127348
    Abstract: The inventors have researched a problem associated with known molding systems that inadvertently manufacture bad-quality molded articles or parts. After much study, the inventors believe they have arrived at an understanding of the problem and its solution, which are stated below, and the inventors believe this understanding is not known to the public. During operation, the gate orifice and nozzle tip position are fixed. The inventors believe that there appears to be no known mechanism that allows optimization of the tip to gate relationship. Known methods of adjusting position of a nozzle tip, such as shimming between a cavity plate and a manifold plate, or replacing nozzle stack components, may be time consuming and difficult. The known hot runner assembly often must be removed from the molding machine to make the desired adjustments.
