METHOD FOR PRODUCING SEMI-PROCESSED PRODUCT FOR MOLDING ROTATING RESIN-BODY, METHOD FOR PRODUCING ROTATING RESIN-BODY, AND HEATING AND PRESSURIZATION DEVICE

摘要

The present invention enables production of a highly reliable rotating resin-body by which a resin molded body can be formed with a simple process, an overlay interface of a base material is not created, and joining strength between the resin molded body and a turning-stopper section provided to an outer peripheral section of a bush made of metal is enhanced. The present invention comprises a first step for aggregating short fiber and a powdered resin on the perimeter of an outer peripheral section of a bush (2) by filtering and dewatering and thereby forming an aggregate (8) of the short fiber and the powdered resin surrounding the outer peripheral section of the bush (2), and a second step for compressing the aggregate (8) of the short fiber and the powdered resin in the axial direction of a rotating shaft to form a molding material (5). Then, the molding material is heated and pressurized to form a resin molded body.
