| Message: | During Power transmission and control technology exhibition in Shanghai last year (PTC Asia), Italian ATOS company asked Richard to find a qualified hydraulic valve block supplier from Chinese hydraulic valve block manufacturers through the exhibition and supply for the branch in Malaysia. He spent a whole day at the exhibition. He went into almost every booth of Chinese hydraulic valve block manufacturers and selected more than 20 Chinese hydraulic valve block manufacturers. He communicated with us AAK for more than half an hour, and took some data with him. When he left, he said that AAK was the Chinese hydraulic valve block manufacturer he spent the most time today. After the exhibition, he would test samples of AAK hydraulic valve block. He would select 6 hydraulic valve block manufacturers from the more than 20 Chinese hydraulic valve block manufacturers he found.
1 week later, Richard sent us the sample drawings and working condition requirements of the hydraulic valve block. This hydraulic pump of ATOS should not only meet the international standards of ISO6020 and 6022, but also have a peak pressure of 450bar. At the same time, it has accuracy requirements for all surfaces of the hydraulic valve block.
2 weeks later, Richard received hydraulic valve block samples from 6 Chinese hydraulic valve block manufacturers. In general, there will be news within 2 weeks after the sample is sent. We asked Richard for feedback but just got reply of waiting for results. We thought it to be no results any more. 1 month later, Richard emailed that the chief engineer of the Malaysian branch advised that 3 of the 6 Chinese hydraulic valve block manufacturers met the requirements, but the accuracy of AAK hydraulic valve block was much higher than that of the other 2 Chinese hydraulic valve block manufacturers. AAK reassured them.
The surface roughness of AAK hydraulic valve block flange reached Ra0 3, which is 30% more accurate than the other 2 Chinese hydraulic valve block manufacturers. |
