<p>A sealing cord(10) of suitable thickness and compressibility is placed between a lower(1) and an upper tool(2) along a line forming a boundary between the different colored molded lining components(5,6). Separate molding cavities are created, one for each color, as the two tools are closed against each other to compress the cord and form the correct molding cavity thickness. Both chambers are then filled with liquid polymers of different colors and allowed to cure so that a skin-like molding is produced and the cord remains on the molding. The upper tool is then removed from the molded skin. The lower tool(1) may have a raised rib, preferably with a pointed cross-section, running along the boundary line between two colored polymers across the tool surface. The sealing cord(10) is positioned in a groove(12) in the upper tool(2). Sealing cord is a flexible, continuous material and can be as the same material as used for the cast colored skin. Both cord and skin layer have the same compressibility when cured. Choice of a suitable colored cord enables the latter to be use a decorative feature. Connection between the cord and the colored layers can be by bonding of by a mechanical grip. The cord may be produced in the tool by introducing a curable liquid or paste. A foam layer may be applied onto the skin layers. An independent claim is included for a lining component for a vehicle interior in which the visible side is formed by a cast skin using the claimed process.</p> |
