| Message: | Hannelore is from Germany and has been engaged in procurement for many years. Their company is going to launch a new hydraulic injection molding machine, which uses hydraulic pressure control valves. He selected a hydraulic pressure control valve manufacturer who has been cooperating for 5 years to make samples, and emphasized that the geometric accuracy of the valve spool and valve sleeve needs to be within 1μm. The manufacturer said that he might not be able to achieve it, but Hannelore believed in the sample capacity of the manufacturer because there were similar cases before. After 45 days, the hydraulic pressure control valve was installed with the equipment and began to test run. However, the movement speed of the actuator of the equipment was unstable. The engineer judged that the hydraulic pressure control valve was not up to the standard. The actual problem was that the geometric accuracy of the valve spool and valve sleeve was not up to the standard, which led to the inflexibility of the hydraulic pressure control valves. The original manufacturer has surrendered, and it will be a waste of time to retest. Hannelore contacted more than 10 hydraulic valve manufacturers. They either have no reply, or said that they were only 80% confident. Hannelore had no time to bet on this 80% confidence, because the exhibition time was approaching. At this time, Hannelore was extremely worried. |
