Publication number: 20100288073Abstract: 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.Type: ApplicationFiled: October 30, 2009Publication date: November 18, 2010Inventors: Gi Ug SHIN, Mun Seok Choi, Young Jong Sung, Dong Hae Suh
