Hydraulic press is widely referenced in many areas of machinery industry, For example in the field of the forging (plastic processing), Hydraulic machines are widely used such as in free forging, drop forging and stamping (for sheet metal forming), extraction, extrusion, shear forming and superplastic forming in many processes; In other fields of mechanical engineering, Hydraulic press was also applied to the powder products, plastic products, Pack, package, diamond shape, correct pressure press, rubber molding, processing, plywood hot-pressing of titanium sponge, and even the very wide range of different industrial areas such as explosives molded. The hydraulic machine body is generally composed of rack , hydraulic ( work and return ) the moving parts and the guide of the cylinder component , and other assistive devices. Auxiliary devices is according to the demand and the creation, such as ejection, perforation equipment, mobile Workbench, heat insulation device. Process requirements are major factors affecting the ontological structure of hydraulic machine,
