The working surface of a 100-ton hydraulic press requires 160×160 cm. Determined through accurate scientific calculations and work experience, first of all, the pressure of the main cylinder of the hydraulic press modification generally ranges from 100 tons, 200 tons, 315 tons, 400 tons, 500 tons, 630 tons, 800 tons to 1,000 tons. The thickness of the object and the size of the mold determine the tonnage of the four-column hydraulic press we choose. The mold is designed according to the size of the building formwork that needs to be produced. The workbench of the hydraulic press can be made larger appropriately. For a 105×105 formwork, the shape of the mold The size is about 140×140, and the workbench of a 100-ton hydraulic press can be as small as 160×160 cm.
