Only AAK Hydraulic Valve Block Benchmarked German Supplier, Richard Admired

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. At the same time, the perpendicularity between the screw hole of
the pipe joint and its external fitting surface is Grade 8. The roughness of
the mounting hole is Ra0 5, which is also 30% more accurate than the other 2
Chinese hydraulic valve block manufacturers. The surface roughness of O-ring
groove is Ra1 5, while the other Chinese hydraulic valve block manufacturers
are Ra5.0-6.5. These data of AAK have been benchmarked with their old hydraulic
valve block suppliers in Germany. Richard quickly made a report to the boss
according to AAK quotation and production time. The accuracy of the hydraulic
valve block is comparable with that of the original supplier, but the price is
20% cheaper, and the lead time is 30-40% shorter.

Richard wondered why among so many Chinese hydraulic valve block manufacturers,
only AAK benchmarked the German factory?

Before processing, AAK uses German COMET flaw detector to detect the blank of
hydraulic valve block to ensure that the internal structure of the hydraulic
valve block is dense and free of interlayer, trachoma and other defects. This
step is generally ignored by other manufacturers. Then select the composite
tool for processing, and combine two or more similar or different hole
processing tools into one special tool. One tool can process the threaded
bottom hole, 45°, 15°, R0.1 chamfering and external counterbore at the same
time, and it can complete multiple processes such as drilling, expanding,
reaming, spot facing and boring in the process of one machining. We don't know
whether there is a second manufacturer mastering these technical essentials,
maybe, maybe not.

The boss was surprised that Richard found such a Chinese hydraulic valve block
manufacturer and asked him to test an order for 500 hydraulic valve blocks.
Richard asked AAK to guarantee on time delivery. The boss said that if it went
well, he would be given a promotion and a raise.

AAK is a trusted hydraulic valve block manufacturer in China. Welcome to
contact us for cooperation.
