    摘要: A mold-tool system (100), comprising: a runner assembly (102) having: a nozzle assembly (104); and a cooling-insert assembly (106) being positioned proximate to the nozzle assembly (104), the cooling-insert assembly (106) being configured to provide, in use, uniform cooling to the nozzle assembly (104). Several potential advantages may be realized with the above arrangement: (i) improvement of hot runner balance by creating a more uniform temperature on all drops, (ii) reduction of energy usage in the hot runner by giving ability to include insulating features, geometry, or materials between the cooling medium and the hot components, and/or (iii) simplification of design since water lines may now be in line with nozzle assemblies.

    摘要: Disclosed is a method of controlling the diameter of a glass rod drawn from a glass preform. The diameter control begins as soon as a glass gob begins to move away from a heated portion of the preform. The velocity of the gob is measured and furnace temperature adjusted to maintain gob velocity at a pre-selected target value. By starting diameter control at this early stage of the process, utilization of the preform is improved as is the utilization of the drawing equipment.

    摘要: A mixer method and apparatus for use generally in injection molding machines is provided. The apparatus and method is generally comprised of a mixer insert that retains a mixing element that is sealingly inserted in the injection molding machine, for example a hot runner manifold. The mixing element reduces the melt imbalances in a flowing melt stream for the formation of improved molded parts.
