Abstract:
1. A method of molding a multiple layer article, comprising: (a) injecting at least one first flowable material into a mold cavity configured to form a molded article comprising the at least one first flowable material, the mold cavity comprising a nonsymmetrical portion relative to an injection location of the at least one first flowable material; (b) co-injecting at least one second flowable material into the mold cavity and interior to the at least one first flowable material; and (c) modifying the flow of the at least one first flowable material and the at least one second flowable material with at least one flow leader in the nonsymmetrical portion of the mold cavity to produce a symmetrical flow boundary downstream of the nonsymmetrical portion and cause the at least one second flowable material to flow throughout substantially the entire mold cavity.
