CO-INJECTION NOZZLE WITH IMPROVED INTERIOR LAYER TERMINATION AND METHOD OF USING SAME

摘要

Disclosed herein are a method and apparatus for combining two or more streams (56) of a polymeric material to form a plastic object (130). The method and apparatus are capable of ending an interior layer of the plastic object at a desired length to avoid the need to clean selected surfaces of components used to form the plastic object. The method and apparatus increase the velocity of the polymeric material used to form the plastic object in certain components used to form the plastic object. The increase in the velocity of the polymeric material facilitates the ending of the interior of the plastic object.
