ABSTRACT:
Method for insert molding film covered plastic parts are disclosed that facilitate wrapping of the paint film around edges of the part. A mold cavity (210) is provided wherein the requisite edge extremities (212, 214) of the cavity (210) are provided in an offset or spaced relation to the mold parting line plane (216). Location of the mold extremities at this position helps to secure the paint film in the mold cavity (210) and prevents pinching of the film that would otherwise occur along the mold parting line (216).
