Press machines require complex controllability of motion. Especially complex hydraulic circuits require specialized knowledge about oil hydraulics. Our inverter hydraulic units achieved multi-stage pressure/flow control by pump with simple hydraulic circuits. By reduction of the motor rotating speed under retained pressure condition, our units offer a high energy-saving performance. Especially press forming machines that need to retain pressure for a long time are ideal applications for Daikin’s inverter hydraulic units.
