Cast plastic skin molding method, especially for components with undercut sections involves placing thin film against upper tool before introducing plastic skin material

摘要

A film (20) is placed over the lower tool cavity (14) and punches (18,30) forming part of the upper tool (28) are moved into the lower tool cavity to clamp the film and hold it partly against the upper tool surface. A plastic material (40) is then cast into a gap (34) between the film and the lower tool tool part (12). Preferred Features: The film (20) is held by a clamping frame on the tool lower part (12). The film can be either a release film or an adhesive film, the latter adhering to the cast plastic material (40).
