Hannelore is from Germany and has been engaged in procurement for many years. Their company is going to launch a new hydraulic injection molding machine, which uses hydraulic pressure control valves. He selected a hydraulic pressure control valve manufacturer who has been cooperating for 5 years to make samples, and emphasized that the geometric accuracy of the valve spool and valve sleeve needs to be within 1μm. The manufacturer said that he might not be able to achieve it, but Hannelore believed in the sample capacity of the manufacturer because there were similar cases before. After 45 days, the hydraulic pressure control valve was installed with the equipment and began to test run. However, the movement speed of the actuator of the equipment was unstable. The engineer judged that the hydraulic pressure control valve was not up to the standard. The actual problem was that the geometric accuracy of the valve spool and valve sleeve was not up to the standard, which led to the inflexibility of the hydraulic pressure control valves. The original manufacturer has surrendered, and it will be a waste of time to retest. Hannelore contacted more than 10 hydraulic valve manufacturers. They either have no reply, or said that they were only 80% confident. Hannelore had no time to bet on this 80% confidence, because the exhibition time was approaching. At this time, Hannelore was extremely worried.

 

Hannelore found AAK Hydraulic Valve on Google, leaving a message: how much can the geometric accuracy of the valve spool and valve sleeve of the hydraulic pressure control valve be controlled. I replied directly, within 1.0μm, no problem. Hannelore sent the drawing of hydraulic pressure control valve and asked for AAK samples. After 40 days, AAK hydraulic pressure control valve samples were sent. After 10 days, Hannelore advised that the geometric accuracy of the valve spool and valve sleeve of each sample of AAK did not exceed 0.8μm. The prototype passed their test run is already on the way to the exhibition hall. Hannelore's depressed mood was finally released. I told him to have a drink in the evening and then just wait patiently for the good news of the exhibition.

 

Last week, Hannelore told us that the exhibition effect was good. He ordered 800 hydraulic pressure control valves first, and emphasized that the delivery time should be on time and the quality should be the same as the trial order. I joked that these are the lowest level commitments in AAK. AAK hydraulic pressure control valves broke his concerns completely with 3 points:

 

1. Swiss high-precision honing machine, the geometric accuracy of valve spool and valve sleeve can be controlled within 0.8μm. With this precision foundation, there is no need to worry about the optimal range of the fitting clearance between the valve spool and the valve sleeve.

 

2. The Mahr cylindricity meter imported from Germany, through EasyForm software, the measurement results can be obtained accurately and quickly. With the help of the software, the workpieces can be quickly adjusted and aligned to improve the measurement efficiency and make the accuracy of each gap consistent.

 

3. AAK is the hydraulic valve supplier of 7 world top 500 enterprises,  its service has been verified for a long time, both in terms of delivery date and manufacturing quality.

 

AAK hydraulic pressure control valves, high precision, long life, you can also try it!
