Abstract
A method is for manufacturing a speaker-use center cap provided with a first cap member layer of synthetic resin and a second cap member layer layered in intimate contact with the first cap member layer and made of a material different from that of the first cap member layer. The method includes: a pre-molding step of attaching a non-molded sheet-like material which is a raw material of the second cap member layer to a mating surface of one of die parts of an injection molding die and thereafter closing the injection molding die to apply a predetermined cap shape to the sheet-like material; and an injection molding step of injecting the synthetic resin material into the injection molding die closed by the pre-molding step to form the first cap member layer to be intimate contact with the second cap member layer.
