| Message: | In March this year, Danielisadora, a Brazilian customer, sent us an inquiry, urgently needing 20 non-standard customized hydraulic flow control valves with an accuracy of 1.0μm valve hole, which is required to be completed within 1 month. Danielisadora has not cooperated much with AAK. Previously, he purchased some SUN hydraulic valves in small quantities but with high requirements. For 20 small quantities of non-standard customized hydraulic flow control valves, most hydraulic valve manufacturers were unwilling to do. After several rounds of email communication, we learned the difficulties that Danielisadora has met.
In the second half of last year, Danielisadora developed a high-performance excavator, which needs a high-precision hydraulic control system as a support, reflecting the high-speed, heavy load and accurate displacement of the equipment. However, the equipment is not smooth in the commissioning stage, and the buffers at both ends of the excavator stick cylinder often fail. Their engineer was puzzled. After disassembling the hydraulic system, it was found that there was a little leakage in the hydraulic flow control valves on the oil cylinder, which was caused by the valve hole accuracy of the hydraulic flow control valves exceeding 1.0μm. The boss asked Danielisadora to solve the problem quickly, because it will miss the exhibition period after 50 days. According to the feedback of the original manufacturer of hydraulic flow control valves, he has no ability to meet the accuracy standard of the 1.0μm valve hole now and has to give up. Danielisadora was helpless. 1 week passed, no manufacturer is willing to try the order of hydraulic flow control valves. The boss had pushed the progress twice, and Danielisadora was under great pressure.
