The invention discloses a double-color molding product and a method. The product comprises a metal shell main body, primary injection molding materials which are combined to the metal shell main body through injection molding are arranged at two ends of the metal shell main body; stripe-shaped grooves are formed in the outer side of each primary injection molding material; secondary injection molding materials which are in injection molding cover outer sides of the primary injection molding materials, and are integrally combined to the primary injection molding materials through injection molding; the primary injection molding materials and the secondary injection molding materials are double-color materials; and the colors of the primary injection molding materials are different from those of the secondary injection molding materials. The materials of the product disclosed by the invention are large in binding force; and the double-color molding product is firm and durable, and simple in manufacturing technology.
