A flexible special device for viscous pressure forming is designed and implemented. By using three proportional electro-hydraulic relief valves connected to a computer for precise control of releasing pressure of the medium, we can form differential pressure distribution in the die cavity. With the cooperation of programmable logical controller (PLC), computer and sensor modules in control system the device can satisfy all the requirements of the new forming process.
