Two-color molding method, two-color molding die and two-color molded article

Abstract

Provided are a two-color molding method, a two-color molding die, and a two-color molded article capable of suppressing deterioration of the appearance quality which is caused by resin shrinkage or resin deformation in a first resin portion in the two-color molding. The method includes molding a first resin portion by a common die and a primary die; and molding a second resin portion by the common die and a secondary die integrally with the first resin portion, in which a shape of the first resin portion is maintained by a holder provided in the secondary die in the molding of the second resin portion. Even when the molded first resin portion is deformed, the shape of the first resin portion is maintained by the holder. Accordingly, deterioration of an appearance quality of the two-color molded article, which is caused by a shape deformation of the first resin portion, is suppressed.
