Patent abstract
A load cell is attached between a fixed axis and an upper die assembly and arranged in a forming chamber. For this reason, the load cell is hardly influenced by reduction of pressure in the forming chamber. A cooling plate is arranged between the load cell and the upper die assembly. An interior of the forming chamber is sectioned into two zones by the cooling plate, a flange and an isolating plate. The upper die assembly and a lower die assembly are housed in the lower zone surrounded by a transparent quartz tube. The load cell is housed in the upper zone surrounded by a cooling chamber. Thus, temperature rise of the load cell can be prevented.
