Abstract

See full text

A tire direct-pressure shaping and electromagnetic induction heating curing method uses an inner metal mold including large and small segments, a telescoping mechanism, supporting plates attached to the segments, and induction heating coils. A cavity in the middle of the segments is filled of phase change material. The temperature of the mold rises rapidly by the thermal effect of an eddy current generated on the surface of the segments to heat the green tire. When the middle part of the segment is heated to a certain temperature, the phase change material absorbs and stores the excess heat. Therefore, the temperature of the middle part of the segment differs from one of two ends of the segment. Once the tire is cured, the inner mold in the expanded condition and the outer mold support very high pressure for the green tire together.
