Electro-hydraulic control cold bending testing machineGWL-50

Main purpose:
This testing machine is suitable for bending tests of metal materials(pipes, bars, plates, construction rebar) using hydraulic bidirectional cylinder loading. After the main oil cylinder performs a cold bending on the sample, the horizontal auxiliary cylinder works to create interference on the sample. After unloading, the bending angle equals the set angle, making it an ideal choice for high-end laboratories. It meets GB/T232 'Metal Material Bending Test Methods'.
