A mold for forming a double-walled thermoplastic article having a molded-in insert, the double-walled article having an outer wall and an inner wall, the insert comprising visible portions that define an outer surface and a plurality of runner sections recessed from the insert outer surface, said mold comprising:
- a pair of mating mold halves, a first of said mold halves including a cavity portion having a first insert section, and a second of said mold halves including a core portion having a second insert section;
- and
- insert-positioning means for positioning the insert in a predetermined position and orientation relative to said cavity portion, said insert-positioning means being located in one of said first or second insert sections;
- said mold halves being configured so that, in a closed position in which said core section extends within said cavity section, said first insert section of said cavity portion and said second insert section of said core portion are positioned in noncontacting adjacent relationship such that an insert portion is formed in the article in which the inner and outer walls of the article are at least partially contiguous, and wherein said cavity portion and said core portion are positioned in adjacent, noncontacting relationship so as to form, respectively, distinct outer and inner walls of the article.
