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.
