PRESS APPARATUS AND PRESS METHOD

摘要

to supply the hydraulic fluid to the pressure cylinder from the pump and pressurizing the molding material by the pressing process at least 3 minutes In the press apparatus and the press method, while achieving an energy saving at the time of pressurization, without complicating the oil pressure circuit, and provides a press apparatus or press control method capable of pressurizing the low-pressure area is also improved. Pump 21 for supplying operating fluid from the cylinder for pressing (14) and a press device for pressing the molding material (P) by the pressing process (H) over 30 minutes to supply the working oil to the cylinder for the pressure from the pump (11) method, can control the number of rotation by the servo motor 20 or the drive motor and also control pump 21 is provided capable of changing the discharge amount, the pressure of the pump 21 to the low pressure region of the control hydraulic pressure set by the process below 2MPa B, and presses the molding material (P) by the pressing step (H) comprises a D. ;
