  • Over-molded preform system and method
    Patent number: 11135751
    Abstract: A system for forming injection molded articles includes a turret, a first mold unit, and a second mold unit. In an embodiment, the turret includes a plurality of core plates and each core plate includes a plurality of core pins. The first mold unit may be configured to form an inner injection molded layer, and the second mold unit may be configured to form an outer injection molded layer over the inner injection molded layer. In an embodiment, the first mold unit and the second mold unit are configured to mold at the same time, and to provide opposing clamping forces. Processes involving over-molded articles are also disclosed.
