Development has all the core technology of forging equipment. Users buy forging equipment is essentially hydraulic adapters buying forging equipment functionality. Who can satisfy all the requirements of the forming process and control of its core technology, will have the right to market discourse. China Metalforming Equipment Manufacturing To achieve the transformation and upgrading, we must increase research on advanced forming process, developed in line with the required equipment, advanced forming process, forming process by forming die --- forming --- shaping parts and equipment --- comprehensive innovation coupled make forging equipment with independent intellectual property rights. Hydraulic power unit (HPU) is used as oil installations, which through external piping system is connected with a number of hydraulic cylinders to control multiple sets of valve movement.
