Product Details

Electro-hydraulic control cold bending testing machineGWL-50


Main purpose:
The testing machine is suitable for metal materialsThe bending test of (pipe, bar, plate, threaded steel for construction) is carried out by hydraulic two-way cylinder. After the main cylinder forms a cold bending of the sample, the horizontal auxiliary cylinder works to make the sample interference. After unloading, the bending angle is equal to the set angle, which is an ideal choice for high-end laboratories. Meet GB/T232 "metal material bending test method".
