AAK Hydraulic Pressure Valve Is Benchmarked With American manufacturer

Mike is a Canadian customer who has cooperated with AAK for more than 2 years,
and he has been very smooth in purchasing hydraulic valves. But in May this
year, he suffered a lot in purchasing this hydraulic pressure valve. The order
for a hydraulic pressure valve originally supplied by an American manufacturer,
was not accepted by the manufacturer due to capacity. He contacted some Chinese
hydraulic pressure valve manufacturers. To his surprise, most manufacturers
offered 20% more than the original American manufacturer, and two of them were
about the same price as the American manufacturer, however, the surface
roughness and diameter tolerance of the hydraulic pressure valve samples were
not up to standard. Mike was distressed that he couldn't find a substitute for
the original American hydraulic pressure valve manufacturer.

Mike knows that AAK HYDRAULIC VALVE is a manufacturer that pays attention to
quality, and its price will be higher than that of its domestic counterparts.
With regard to this hydraulic pressure valve, he emailed me and asked why most
manufacturers offered 20% more than the original American manufacturer? For
this abnormal situation, I told him directly that it must be due to the high
defective rate of processing. AAK is confident that the price is cheaper than
American manufacturer, and the quality is not inferior to American
manufacturer.

According to the drawings of the hydraulic pressure valve issued by him, AAK
technical team found that the processing was really exquisite. It requires that
the coaxiality and roundness of the Φ8mm/Φ9mm hole should be less than 5μm,
and the Φ15mm/Φ9mm orifice should be free of burrs. To guarantee coaxiality
and roundness requirements of 5μm, and keep the inner wall of the hole at
0.6μm roughness, at least 50% of valves should be scrapped according to the
existing processing technology. This confirms my guess that why the quotation
of domestic manufacturers is 20% higher than that of American original
manufacturer.

Mike was not calm after receiving the quotation of AAK hydraulic pressure
valve. He repeatedly confirmed with me whether the price was wrong? The price
of AAK is not only cheaper than that of domestic manufacturers, but also 30%
cheaper than that of American manufacturer. I told him that this hydraulic
pressure valve can only be drilled and reamed for many times by domestic peers,
which not only has a long processing cycle, but also is difficult to ensure the
processing accuracy. At the same time, the whole hole processing including tool
change time is at least 210 seconds, and most of the tool life is less than 500
holes, which is time-consuming, money consuming, and what is worse, the
qualified products are very limited. Of course, the cost is high. Mike asked me
to try the sample directly. 2 weeks later, we sent the hydraulic pressure valve
sample. 5 days later, Mike’s team confirmed the quality of AAK hydraulic
pressure valve at one time, and the production time provided by AAK was less
than half of domestic peers.

For processing this hydraulic pressure valve, we use integral cemented carbide
tools, and use 3 efficient tools to replace the original 9 tools. We also use
special guide strips and internal cooling design to maintain tool life and
improve cutting speed and machining accuracy. The number of inner holes can be
stabilized at 3000, which is 6 times that of peers. The internal leakage of the
whole machine has also been reduced from 1.6 to 1.1, and the processing and
tool change time has been reduced to 45s, which is only 22% of peers. Such
efficient and high-quality processing is not our temporary idea, but the result
of adhering to technological innovation. There may not be such a second
hydraulic pressure valve manufacturer in Ningbo.

AAK hydraulic pressure valve is benchmarked to the quality of American
manufacturer. You are welcome to test an order.
