The hydraulic universal testing machine stands as a heavy-duty testing platform engineered to execute diversified mechanical performance assessments for various metallic raw materials and finished metal components. Supported by stable hydraulic power output and precise digital closed-loop control, the apparatus completes tensile, compression, flexure and shear examinations on carbon steel, alloy metal, aluminum profiles and other metallic workpieces. It precisely captures critical indicators including yield threshold, ultimate breaking load, elastic modulus and fracture elongation. Equipped with interchangeable fixture sets, the equipment adapts to specimens in plate, rod and tubular shapes, satisfying routine incoming inspection, product verification and material development demands for metal manufacturing factories and third-party laboratories worldwide.
