| 20100288073 | STEERING WHEEL FOR AUTOMOBILE AND METHOD OF FABRICATING THE SAME - The present disclosure relates to a steering wheel for automobiles and a method of fabricating the same. The steering wheel is formed in multiple layers having a thickness difference of 2˜3 mm by multi-stage injection molding and has a pattern or picture between the layers to provide a luxurious and pleasant appearance. In the method, after being preheated in a dryer to remove moisture, a metal frame is subjected to primary to tertiary injection molding in a mold to form the multiple layers. Here, drying is performed to remove moisture from the surface of injection-molded parts to prevent deterioration in adherence and quality during the process. Here, the pattern or figure is inserted between the layers by pad printing or a combination of pad printing and vacuum deposition. The multi-stage injection molding allows various colors, patterns, and figures to be printed on injection-molded parts excluding the uppermost layer. | 11-18-2010 |
