AAK hydraulic pressure control valve with 1μm Accuracy Tolerance

At the beginning of June, Trinidad, a Spanish customer, emailed us a re-order
for 600 hydraulic pressure control valves, which has been repeated for 5
consecutive times since the sample was successful in the second half of last
year. The high-frequency repeat orders also mean that their equipment sales are
booming. Since using AAK hydraulic pressure control valves with 1μm accuracy
tolerance and opening and closing property of 1 second, their equipment sales
increased by nearly 40% year-on-year. Trinidad, the purchasing manager, was
also promoted to director.

In the second half of last year, Trinidad was anxious to purchase a batch of
hydraulic pressure control valves for hydraulic swing milling and riveting
machines. Because the equipment had high requirements for the accuracy and
opening and closing of hydraulic pressure control valves, Trinidad spent 2
weeks looking for more than 20 hydraulic pressure control valve manufacturers,
and none of them was 100% sure to be successful. Trinidad selected the 2 most
suitable manufacturers to make samples. 45 days later, although the trial run
of the riveter was successful, the working efficiency of the equipment was not
high and the sales were not optimistic. Their engineer said that to change this
situation, they must adopt the hydraulic pressure control valves with accuracy
tolerance and opening and closing property of 1 second. Trinidad had a big
headache due to this purchase.

By chance, Trinidad got into touch with me through the introduction of AAK's
old customer Burgos. After discussing the drawings of his hydraulic pressure
control valve, our technical team basically already knew it. After 30 days, 20
hydraulic pressure control valve samples were sent out. 2 weeks later, Trinidad
informed that the working efficiency of the equipment was at least 20% higher
than before, and the accuracy tolerance of the hydraulic pressure control valve
was controlled within 1μm, the opening and closing performance is less than 1
second, which is great.

As early as 5 years ago, AAK had Japanese ultra-high precision machine tools
for processing in the military industry, which were operated by specially
assigned personnel. There are no more than 3 hydraulic cartridge valve
manufacturers who have such machine tools in Ningbo. To make sure that the
accuracy tolerance of hydraulic pressure control valve is controlled within
1μm, the opening and closing performance is less than 1 second, valve hole
processing is the core, and AAK has 3 advantages to guarantee it:

1. On the equipment, the machining accuracy of our machine tools for components
can reach 0.1-0.8μm. , the valve hole accuracy of each hydraulic pressure
control is the same, while the valve hole accuracy of most hydraulic cartridge
valve manufacturers can only reach 1-3μm at most. That is, the machining
accuracy of AAK is more than 10 times that of them.

2.In terms of process, it realizes the personalized customization of the valve
hole accuracy of the hydraulic pressure control valves, and 95% of domestic
hydraulic valve manufacturers just make the general size of the industry.

3.In terms of detection, the German Diatest small pore diameter high-precision
measuring instrument is used to accurately measure each hydraulic pressure
control valve hole, and the minimum measurement accuracy range can reach
0.1μm.

Some time ago, Trinidad privately informed that their equipment sales were
becoming, more and more popular, and he was promoted to purchasing director.

AAK hydraulic pressure control valves, accuracy tolerance 1μm. Opening and
closing for 1 second, it is difficult to find competitors in Ningbo, you can
also have a small try.
