More Information
Summary:An inner mold having, on the outer surface thereof, corrugations matching the shape of the bellows, and an outer mold having, on the inner surface thereof, corrugations matching the shape of the bellows, are used. An airbag that is previously and at least partially formed into a bellows shape is placed on an outer side of the inner mold so as to cover at least a corrugated part with the airbag. A cylindrical preform comprising unvulcanized rubber and a reinforcement material is placed on the outer side of the airbag. An outer mold is placed on the outer side of the preform. A pressurized fluid is supplied between the inner mold and the airbag so as to inflate the airbag. The preform is vulcanized under heating while being pressed against an inner surface of the outer mold, whereby a reinforced rubber hose is manufactured.
