| Message: | 9 months ago, we received an email from an old customer in the UK, informing that Berge had transferred from the quality control department to the import department. We could see from the email of the young man's self-introduction that he was full of confidence in procurement. Unfortunately, the first hydraulic valve order went wrong. A batch of orders for hydraulic flow valves shipped from a hydraulic valve manufacturer in Ningbo had no problem when tested before leaving the factory. However, when the goods were delivered to customers, the company received a series of quality complaints from consumers in only 1 month, and nearly 20% of the hydraulic flow valves had leakage. The boss was not very happy, and requested Berge to solve the guest's complaints within 1 week.
Berge had discussed with the original hydraulic valve manufacturer several times, but it has not been effectively solved, and he even wanted to resign. Shawn, a former old purchaser, felt his frustration and reminded him to communicate with AAK HYDRAULIC VALVE to see if it could be solved.
We received Berge's email with product drawings, pictures and test data of the defective hydraulic flow valves. We preliminarily judged that there was a problem with the valve spool. In order to solve the problem at one time, Berge asked his hydraulic valve manufacturer to send 5 samples of defective hydraulic flow valves to AAK HYDRAULIC VALVE for thorough inspection.
After receiving the hydraulic flow valve samples, frankly speaking, the main line type of the hydraulic flow valve was acceptable. The problem was that the valve spool deviated from the central axis, resulting in leakage. Of the 5 hydraulic flow valve samples sent, two were in this situation, and the other three were of acceptable quality. This proved what we said before that it was difficult to 100% ensure that the valve spool did not deviate from the central axis due to human error, which was a hidden problem among peers. I suggested him to
