As an important process of explosive molding compression,the accuracy of pressure maintaining would affect the quality and safety of the product. The leak rate of 6 MN precision hydraulic press machine was analyzed and calculated. Based on the results,the suitable type accumlator and proportional pressure reducing valve were used to supplement pressure in the pressure maintaining process of 6 MN hydraulic press machine. The results show that the system pressure can maintain in 20 MPa for 120 min,and the pressure error is less than ±0.1 MPa.
