HWQ - 40A type a vertical double working station hydraulic bending testing machine adopts the combination technology of hydraulic loading and single chip microcomputer system , it is mainly used for the bending test for metal or nonmetal material or product manufacturability. It is composed of the test host, oil source (hydraulic power source), measurement and control system, test instruments of four parts.

HWQ-40A type bending testing machine meet the GB/T 232-99 metal material bending test requirements. Bending distance through the level of oil cylinder stroke control, which is very convenient.

Test force does not step all the test, the resolution is better than 1.5 N, test forces of relative error within ±1%, test range 1% - 100%.

The tester can be used in metallurgical construction quality inspection department, production enterprise deformed steel bar bending, can also be used for construction materials, steel welding point bending performance testing, which is the commonly used equipment for metallurgical enterprises, research institutes, quality inspection, construction, railway, transportation, colleges and universities and the non-ferrous metal industry material bending performance test and study.
