Abstract
An apparatus for forming a frame including a rigid thermoplastic portion and a resilient portion defining a lip seal. In particular, a core/cavity mold assembly is provided, wherein the rigid thermoplastic portion is formed, by opening the mold assembly while maintaining the rigid thermoplastic portion in the core, placing the core in line with a second cavity configured and sized to form the lip seal and molding the lip seal directly onto the rigid thermoplastic portion. The mold cavity is provided with movable internal and external stripper rings that allow the resilient portion to be removed from the cavity.
