| Message: | At the beginning of this year, Samuel asked by email about the production time of 1,000 hydraulic needle valves, He specially emphasized that the technical parameters of the hydraulic needle valves need to be the same as those samples made before, especially the valve hole accuracy must be 100% within 1μm or less. Samuel has been cooperating with AAK for 3 years. It is the first time that he deliberately emphasized as such in email. After communication, I learned that the hydraulic needle valves that AAK made samples for last time was 20% higher than that of other hydraulic valve manufacturers, so he placed the order with another manufacturer. However, now this batch of hydraulic needle valves have been complained by customers that the hydraulic winch is stuck. The root cause is that the accuracy of the hydraulic needle valve holes is uneven, and some are less than 1μm, and some higher than 1μm. After the original hydraulic needle valves were replaced by the manufacturer, complaints still continued. The boss was very dissatisfied with Samuel's purchase this time and asked him to source another hydraulic needle valve supplier. |
