The 1,200-ton three-beam, four-column, three-cylinder hydraulic press combines servo technology and vacuum cover design. It adopts CO2 welding of all steel plates. After welding, it is tempered and vibrated to ensure that the press body does not deform. 

      The workbench is also welded with high-quality steel plates and subjected to vibration aging treatment. To eliminate internal stress, the columns are made of high-quality 45# steel. The four columns are all surface-moderate-frequency quenched and hard-chromium plated, which improves the overall rigidity and durability of the equipment. Compared with traditional single-cylinder or dual-cylinder designs, the three-cylinder design can provide more stable and balanced pressure output. The hydraulic system is controlled by an integrated cartridge valve, which is sensitive, reliable and leak-free. The electrical system is controlled by a PLC programmable controller.

      The vacuum cover is made of high-strength, high-sealing materials, which can effectively isolate the workpiece from the external environment, prevent the workpiece from being contaminated or oxidized during processing, and can extract the air from the cover before processing to form a negative pressure environment. It helps reduce the deformation and cracks of the workpiece during processing and improves the processing quality of the product. The design of the servo vacuum cover can also effectively protect the workpiece from splashes, sparks, etc. during processing, improving the safety and integrity of the workpiece.
