Abstract
A method for molding a non-pneumatic tire includes placing a hub into a lower mold portion, and associating at least one temperature sensor with the lower mold portion. The method further includes placing an upper mold portion onto the lower mold portion and the hub, heating the mold assembly, heating a molding material, and transferring the heated molding material into the interior of the mold assembly. The method further includes heating the mold assembly and molding material until the at least one temperature sensor indicates that the molding material has reached a first temperature, and maintaining the temperature of the molding material at the first temperature for a first predetermined period of time. The method further includes reducing the temperature of the molding material to a second temperature after the first predetermined period of time, and separating the upper mold portion and molded tire from the lower mold portion.
