The low-temperature bending test for washing machine hoses is customized according to relevant testing requirements and standards, and is suitable for conducting durability life tests on the inlet and outlet pipe components of washing machines under specified environmental temperatures. The testing machine meets the requirements of relevant testing standards such as GB/T4288 for the bending life testing machine of washing machine drainage pipes. It mainly consists of high and low temperature environmental test chambers, bending mechanisms, control systems, and other parts. The box is made up of external powder coating and internal 304 # stainless steel material welded together. It adopts PID constant temperature and humidity technology, PLC program control, and servo drive as the driving source. By customizing hose fixing fixtures to fix the tested hoses, durability life tests and constant temperature tests are conducted on the tested hoses according to the test times, angles, and times set by the 7-inch touch screen. The device is easy to operate and does not require dedicated personnel. The relevant test data can be exported via USB.
