摘要
Methods and systems for co-injection molding multilayer articles having one or more molded apertures disposed between a gate region and a peripheral region of the article are disclosed. The articles include an interior layer disposed between an inner layer and an outer layer. An article has interior layer coverage over at least 98% of a perimeter of a cross-section of the article downstream of the one or more molded apertures. A method includes modifying fluid flowing past an aperture-forming region of a mold cavity to compensate for the drag of the aperture-forming region on the velocity of the fluid flowing proximal to the aperture-forming region.
