PURPOSE:To shorten the time of molding cycle by setting the initiation time of heating of tablets to become a molded product at the time which is advanced from the prearranged time of clamp-finishing by the actual heating time unit the temperature of the tablets reaches prescribed temperature from the initiation of heating carried out immediately before the heating of the tablets. CONSTITUTION:The top force 11a and the bottom force 11b of molding dies 11 are mutually contacted closely and are clamped, and then the tablets 31N+1 of powderlike thermosetting resin is heated at prescribed temperature. Said tablets are charged in the pot U of the molding dies 11, and then it is pressurized in the pot U and is pushed into the cavity C of the molding dies 11, and further is heat-cured in the state as it is in said cavity, thereby obtaining a molded product. Then the initiation time of heating of the tablets is set at the time which is advanced from the prearranged time of clamp-finishing by the actual heating time until the temperature of the tublets reaches prescribed temperature from the initiation of heating carried out immediately before the heating of the tablets. |
