The assembled hydraulic press first measures the core index-pressure accuracy ! Measured with a high-precision pressure sensor, the rated pressure of 100 tons of models, the pressure error ≤ ± 1 %, far below the industry standard of ± 3 % ; from 5 tons to 100 tons of grading test, each stage of pressure response speed is less than or equal to 0.5 seconds, the pressure uniformity of the pressing position is 98 %, to ensure that the force of the workpiece is consistent !
