PROBLEM TO BE SOLVED: To provide a mold which produces hot-molded goods of superplasticity processing material with high quality and at a low cost. SOLUTION: Graphite is used as a mold material for a punch 1 and a mold 2 which eliminates the use of lubricating oil. By installing a high-frequency induction coil 4 inside the mold, the molding operation is performed by heating up to the temperature level for superplasticity processing in a short time. Also, the occurrence of deformation on the plain part is prevented using running cooling water through the cooling water channel 6 of the base presser box 5.
