Zusammenfassung:	A pressure-type control method with shift monitor for the hydraulic forming machine using powder as raw material is disclosed. A shift sensor is used to monitor the relative shift between upper and lower moulds. The shift value is used as the feedback parameter of closed-loop hydraulic control system. When the relative shift value is correspondent with the predefined thickness variation of powder, it is determined that the powder has been pressed by a predefined pressure, so performing a closed-loop control.
