Abstract

The invention discloses a steering wheel for automobiles partially molded from a wood-grain film and a manufacturing method thereof. In particular, it relates to a steering wheel for automobiles which is partly integrally molded with non-foamed polyurethane resin and molded with a wood-grained film, thereby having a good woody feel, and a wood-grained film molded with non-foamed polyurethane resin. The resin part is molded to improve the adhesion of the film to the manufacturing method of the steering wheel of the car. The manufacturing method of the automobile steering wheel includes 1. mixing raw materials; 2. installing the steering wheel between the upper and lower metal molds and connecting the upper and lower metal molds to prepare for non-foaming molding; 3. injecting the mixed raw materials to make non-foaming polyurethane resin molding And take out the product; 4, remove the burr (burr) on the product and clean it; 5, dry and grind the surface to remove the pores; 6, fill the surface pores and re-dry and grind the surface to remove the pores and other six processes.
