ABSTRACT:
A method and apparatus for creating distinct zones in a mold that can be separately filled, particularly with different materials. A molded barrier is created within the mold and the mold is configured so that the barrier separates zones in a mold cavity. Different materials may then be injected into the separate zones to create a molded article constructed of multiple materials.
