ABSTRACT:
A method and apparatus for manufacturing a film-covered flange having the following steps. An injection molding press having a mold cavity and a core receives a pre-molded thermoformed film. The film is formed to have an in-turned flange portion that will form the covering for the final article. The film is placed within the mold cavity. The core has a slide movable between retracted and extended positions. The slide is retracted and the core is moved within the mold cavity. After the press is closed the slide is moved from the retracted position to the extended position. The slide includes a recessed portion that lies opposite the flange portion to create a space therebetween. A molten plastic material is injected into the space. The plastic material adheres to the flange portion and forms an article having a covered flange.
