Abstract
A two-color molding method in which, when a secondary molded body is formed by covering the surface of a primary molded body made of a reinforcing-fiber-containing synthetic resin material with a reinforcing-fiber-free synthetic resin material, these synthetic resin materials may differ and the production cost does not increase. When a primary molded body is formed by injecting a molten reinforcing-fiber-containing synthetic resin material into a primary molding cavity, the molten reinforcing-fiber-containing synthetic resin material flows from one end toward the other end of the primary molding cavity and a short shot is performed. This exposes reinforcing fiber in a tooth of the primary molded body positioned at the other end of the primary molding cavity. In the secondary molding cavity, the tooth in which the reinforcing fiber is exposed is covered with a reinforcing-fiber-free synthetic resin material to form a synthetic resin gear as a two-color molded body.
