Body made of high quality Q235A steel plate welded structure, with open C structure, heat treatment to eliminate internal stress, with good rigidity, the processing is the use of imported machine tools once clamping processing is completed, the main drive bearings with copper alloy by liquid nitrogen after frozen group into the body to make it to the expansion in a certain period of time the two one after finishing. So the precision is guaranteed to be within 0.03mm. The foot pad configuration, has high damping effect. Longitudinal crankshaft, compact structure, beautiful appearance; material and become, as 42CrMo after forging by professional testing equipment to ensure the quality of materials to visit, and the density of standard, complete strength test, after quenching, high frequency processing, precision grinding machining, fully guarantee precision within 0.01mm. The block with high quality material casting structure, has high shock absorbing effect. Internal stress treatment was eliminated by tempering. Using hexahedral rectangular guide, the material of the guide rail is alloy copper, high wear resistance, good stability, high precision. The height adjusting device of the mould: the closed type high electric regulation, the display precision of the slide block height is 0.1mm. The built-in transmission turbine ensures the smoothness and precision in adjusting the mode height. The hydraulic overload protection device is adopted in the slide block: the overload of the gas-liquid type exceeds 10% of the rated tonnage,
