<p>A method and apparatus for manufacturing a film-covered flange comprising the following steps. An injection molding press having a cavity (12) and a core (14) receives a pre-moulded thermoformed film (18). The film (18) is formed to have an in-turned flange portion (24,26) that will form the covering for the final article. The film (18) is placed within the mold. The core (14) has a slide (30,32) movable between retracted and extended positions. The slide (30,32) is retracted and the core is moved within the mold. After the press (10) is closed the slide (30,32) is moved from the retracted position to the extended position. The slide includes a recessed portion (34,36) that lies opposite the flange portion (24,26) to create a space (42) therebetween. A molten plastic material is injected into the space (42). The plastic material adheres to the flange portion (24,26) and forms an article having a covered flange. <IMAGE></p> |
