Description

Just yesterday, I received a repeat order from Andy for hydraulic flow control valves, which is just 3 months away from the delivery time of the last batch of hydraulic flow control valves. The American customer Andy, started to communicate with us in 2019. Maybe it was just not the right time, we still didn't partner with each other till the beginning of this year. Because of encountering a Waterloo at the previous hydraulic valve manufacturer, he turned the tables at AAK and regained his confidence.

 

At the end of last year, Andy purchased a batch of hydraulic flow control valves from a hydraulic valve manufacturer, but 20% of the products leaked, he received claims from customers. The original hydraulic valve manufacturer was unwilling to bear the claim or re-produce the goods. The customer kept pushing for free replacement hurriedly. The boss asked him to find a high quality hydraulic valve manufacturer to reproduce the goods for the customer.

 

Andy had a big headache at that time. Because the replacement quantity is not big, the hydraulic valve manufacturers with high quality were unwilling to run mass production for a small quantity, while those who were willing to produce this quantity, were not able to meet the customer requirement about the roughness of hydraulic flow control valve. He ran into a wall everywhere, which made Andy haggard.

 

When Andy contacted with AAK HYDRAULIC VALVE, we are willing to cooperate with him to solve this difficult problem. We tested the leaked hydraulic flow control valve samples. The reason for the leakage is the roughness of the mounting surface of the hydraulic flow control valves. According to the customer service conditions, this roughness must be controlled at 1.0μm or below. Andy is very confused why 80% of the mounting surface roughness of hydraulic flow control valves is up to standard, while 20% is out of this range. The root of this fluctuation is the master's operation method, resulting in human error. The surface roughness is the depth, density, texture of the traces left on the machined surface from the action between the tool and the part surface, which depends on the master's processing technique.

 

Andy is very clear that at present, most domestic hydraulic valve manufacturers generally control the roughness of the mounting surface of hydraulic flow control valve at 0.8-1.0μm, but not stable, which is the biggest problem. Andy also knows that only AAK controls the roughness value of hydraulic flow control valve within 0.8μm, which can completely avoid leakage outside the hydraulic flow control valves, because of rest assured, Andy decided to repeat the order with AAK HYDRAULIC VALVE.

 

We AAK HYDRAULIC VALVE, first determine the material according to the roughness value required by the customer, and then determine the cutting process of the material according to the characteristics of the material. The workshop produces it in strict accordance with the process sheet. Technically, we abandon the traditional grinding technology and use "turning instead of grinding". Equipped with high-precision CNC lathes, we refit elastic cutting tools by ourselves, and use automatic measuring instruments. The Ra value of hydraulic flow control valves is controlled in the computer at all time, which can eliminate man-made errors and prevent the fluctuation of Ra value of hydraulic flow control valve completely.

 

AAK hydraulic flow control valves, produced with ingenuity, can be purchased and used at ease.
