PROBLEM TO BE SOLVED: To shorten the time required for a separator manufacturing process, and enhance productivity of the separator by quickly raising the temperature of a preform with a first heating means and a second heating means during the compression molding of the preform, and accelerating curing, by keeping the raised temperature of the preform with the first heating means, after the second heating means has stopped. SOLUTION: The heating means, comprising electric heaters 21, 26 and a direct resistance heating device 28, in installed at the starting of heating, the electric heaters 21, 26 and the direct resistance heating device 28 are energized; and thus after the elapse of the specified time, or reaching a specified temperature, power supply to the direct resistance heating device 28 is stopped. |
