Patent number: 7497509Abstract: A fender liner includes a surface layer serving as the outermost layer and an inner layer located between the surface layer and the outer surface of a wheel well. The surface layer and the inner layer are formed of nonwoven fabric. The nonwoven fabric forming the inner layer has a higher tensile strength than that of the nonwoven fabric forming the surface layer. Accordingly, the fender liner has a favorable noise reduction capability, and has a sufficient rigidity to bear a weight increase due to water absorption. Alternatively, the nonwoven fabric forming the surface layer may have a higher bulk specific gravity and a smaller fiber diameter than those of the nonwoven fabric forming the inner layer. In this case, the noise reduction capability and the durability are both improved.Type: GrantFiled: March 7, 2006Date of Patent: March 3, 2009Assignee: Toyoda Gosei Co., Ltd.Inventors: Yoshimasa Omiya, Daiichiro Kawashima, Yoshiaki Shichida, Koichi Sato, Mitsunari Tanaka

Patent number: 7459114Abstract: A method for molding an in-mold coating product including a substrate and a coating formed on a surface of the substrate. A first mold including a fixed mold piece is closed to form a substrate cavity therein. The substrate cavity is charged with a resin to form the substrate with a seal projection formed near the parting line of the first mold. Then, a second mold, which uses the fixed mold piece of the first mold, is closed with the substrate arranged on the fixed mold piece to form a coating cavity therein. The second mold deforms the seal projection so that when a coating material is charged into the coating cavity, the coating material does not leak out toward the parting line of the second mold.Type: GrantFiled: November 30, 2004Date of Patent: December 2, 2008Assignee: Toyoda Gosei Co., Ltd.Inventors: Hiromi Hyuga, Koichi Ueno, Nobuyoshi Baba, Daiichiro Kawashima
