Although as early as the mid-17th century Pascal discovered the use of liquid can produce the possibility of great power, It was not until the 19th century, hydraulic technology to receive widespread attention. In response to the military, aviation industry and other areas of demand, Germany, Britain, the Soviet Union and other countries has created a number of Nominal pressure reached 10,000 tons of forging hydraulic press. This time forming hydraulic machinery were fully developed and is a mature technology. Hydraulic press widely used in the sheet metal stamping drawing, metal machine parts pressure forming; powder products industry; non-metallic materials to suppress forming; wood products in areas such as the hot press forming. Hydraulic highly versatile for its industrial production in the area of the important status and become an indispensable national product of a &quot;pawn.&quot;</p><p>In this paper, hydraulic molding machine to do a simple review and sum up, and specifically designed for a Nominal pressure of 2500 kN Hydraulic presses, focused on the design of the hydraulic system, the elaboration of the hydraulic pressure system, the direction of control loop, rendering The hydraulic system map, and select the various hydraulic components such as the specific models.</p><p>In order to meet the needs of industrial production, promote economic development, China must increase the hydraulic molding machinery design and manufacture of the research and development and to strive for an early reached the international advanced level, breaking the Western developed countries on key components of the hydraulic technology monopoly.</p><p>Key words: hydraulic machine; hydraulic cylinder; hydraulic system;
