AAK Hydraulic Pressure Control Valve, 5% higher finish machining accuracy

George comes from a hydraulic valve company in Germany. He likes to choose old
suppliers to place orders. Some time ago, he placed an order of hydraulic
pressure control valve with machining allowance of 0.3mm with an old supplier.
After 3 proofing, his customer still did not approve the samples of the
hydraulic pressure control valve. George was very angry. Before ordering this
hydraulic pressure control valve, he confirmed the parameters with the
manufacturer several times, especially the machining allowance of 0.3mm. The
manufacturer guaranteed no problem. Unexpectedly, the accuracy error of the
hydraulic pressure control valve sample was 10% higher, and even after revising
samples for 3 times, it still can not meet the machining allowance of 0.3mm.

George has to face the technical shortcomings of the old manufacturer, the
sample pushing of the customer, and the situation of no suitable hydraulic
pressure control valve manufacturer to make samples. He contacted the all the
hydraulic valve manufacturers cooperated in the past, but none of them was able
to make a hydraulic pressure control valve with a machining allowance of 0.3mm.
He kept looking for a new hydraulic pressure control valve manufacturer online
and came across AAK hydraulic valve on B2B. George left a message on our
website www.aakindustry.com: I saw AAK article introducing the hydraulic valve
with machining allowance of 0.3mm. We have a hydraulic pressure control valve
requiring machining allowance of 0.3mm. Can you sample it?

For those customers who directly require to make samples like this, basically,
they encountered the sample failure from other hydraulic pressure control valve
manufacturers. After communication, we know that his old supplier has failed to
deal with the 0.3mm finishing hydraulic pressure control valve samples for 3
times. After checking George's hydraulic pressure control valve drawings and
various parameter descriptions, AAK engineers confidently informed that the
sample could be successful at one time. George may think that only AAK can help
him solve the problem. He directly paid a proofing fee of $1,200.00 and asked
us to send the hydraulic pressure control valve samples within 3 weeks. We
appreciated George's frankness and asked the workshop to cooperate fully. After
15 days, we successfully sent the samples of hydraulic pressure control valves.
On the third day after George received the samples, he told us that the
machining accuracy of AAK hydraulic pressure control valve not only met the
requirement of machining allowance of 0.3mm, but also increased by 5%, which
made him admire very much.

In order to ensure the accuracy of finish machining size allowance, the heat
treatment process is the most critical step. At present, most hydraulic
pressure control valve manufacturers adopt local quenching, the workpiece heat
treatment process is not easy to control, and most of them are easy to deform.
As early as 6 years ago, AAK adjusted local quenching to overall quenching. At
the same time, vertical flow treatment must be required for the hoisting mode
in the process of quenching and tempering, so as to minimize the influence of
the tissue stress and thermal stress of the workpiece heat treatment on the
deformation, so as to meet the dimensional allowance requirements of finish
machining.

The next day, George decided to cancel the order of the hydraulic pressure
control valves with the old manufacturer and told me that AAK hydraulic valve
is his old supplier now. Maybe he meant to tell me that his hydraulic pressure
control valves will be purchased from AAK in the future.

AAK hydraulic pressure control valves, the finish machining accuracy is 5%
higher than the requirements of German customer. You can also have a small try!
