| Message: | When back from the Spring Festival, we received a reorder for 120 hydraulic threaded cartridge valves from Echerle company. Dean has been engaged in hydraulic parts purchasing in Echerle company for many years, and has been doing very well. The boss also trusts him. At the beginning of last year, the company developed a new hydraulic power unit, which has high requirements for the accuracy of the hydraulic threaded cartridge valve to be used. Because of the high accuracy requirement, the original hydraulic threaded cartridge valve manufacturer said that he was not able to achieve it. Dean used a new hydraulic threaded cartridge valve manufacturer finally. After their hydraulic power unit equipment has been sold for just less than 3 months, the customer complained about insufficient power supply. Their engineers believe that the hydraulic threaded cartridge valve was stuck and caused the problem. However, the hydraulic threaded cartridge valve manufacturer believes that it is caused by the uncleanness of hydraulic oil, but the engineer detected that the hydraulic oil is normal.
The owner was not satisfied with such a hydraulic threaded cartridge valve manufacturer and asked dean to find a new hydraulic valve manufacturer and replenish goods as soon as possible. Dean left a message on AAK website and asked, what are the reasons for the stuck of the hydraulic threaded cartridge valve? We estimated that he had encountered the complaint about the stuck of hydraulic threaded cartridge valve. After communication, we learned that he was cheated by the new hydraulic valve manufacturer.
According to the hydraulic threaded cartridge valve drawings sent by him, the accuracy requirements are high, especially the dimensional accuracy requirement of the valve hole is IT7 ~ 4. Among the hydraulic valve manufacturers in Ningbo, there may be no more than 3 factories that are able to meet it. We suggested Dean send the abnormal hydraulic threaded cartridge valve to |
