Heavy Industry Machinery The fast forging hydraulic press has high speed and large impact load, so it will have a huge test for the fatigue strength of the cylinder, the life of the seal, and the guiding support mechanism. Kelin adopts a special guide support design to ensure that the cylinder can withstand huge lateral loads, and a reasonable structural design ensures that the cylinder is safe and durable. The bore of the largest plate press cylinder manufactured by Kelin is 1000mm.
