Dimon is a new buyer of a hydraulic equipment manufacturing company in the United States. In the second half of last year, he purchased 100 hydraulic needle valves from an old supplier. After receiving the goods, the hydraulic needle valves were installed on the equipment. A few months later, some users complained that the pressure supply of some equipment was insufficient. Their technicians judged that the radial jamming of the valve spool of the hydraulic needle valve resulted in no flow regulation, which would lead to the failure of the power unit. The hydraulic needle valves need to be replaced with new ones as soon as possible to eliminate user complaints. His boss is not very satisfied that problem happened on even such a small number purchasing of hydraulic needle valves.
Dimon is confused why the hydraulic needle valve supplier who had cooperated for 2 years would have such quality problems. He sent some problematic hydraulic needle valves back to the factory. The manufacturer replied that the accuracy of these hydraulic needle valves met the standard, but a small deviation in the size of the valve spool was caused by the deviation of the assembler. At that time, several valves were assembled at the same time in the assembly workshop, and a few deviations were difficult to avoid. Dimon realized that even the original manufacturer replaced the hydraulic needle valves with new ones, it still can not solve the problem of the radial jamming of the valve spool for 100%. He was afraid that if there were more user complaints, could he keep his job during the probation period?
Dimon decided to find a new supplier of hydraulic needle valves. He left a message on our website: Can you solve the problem of radial jamming of the valve spool of hydraulic needle valve? At first, it was hard to answer this question. After several rounds of communication, we learned the story of his purchase of these 100 hydraulic needle valves. After reviewing the working conditions and drawings of hydraulic needle valve from Dimon, as well as the pictures of hydraulic needle valves from the original supplier, AAK suggested him trying samples directly. 20 days later, AAK sent 10 samples of hydraulic needle valves made per his requirements.
Two months later, Dimon sent an email to us saying that he selected 5 factories from more than 20 hydraulic needle valve manufacturers to make samples. Only the samples from AAK and another factory did not have the problem of radial jamming of valve spool during the test. Their engineers suggested that AAK should be selected to replace the 100 hydraulic needle valves with potential quality problems, because the parameters of AAK hydraulic needle valve are the most stable. The boss knew that he dared to develop new suppliers and solved the hidden quality problems, although the probation period is not over yet, Dimon was approved to become a regular in advance. He told us this story privately.

For the valve hole accuracy 1 m hydraulic needle valve, although AAK is 20% more expensive, its service life is twice that of its peers At the beginning of this year, Samuel asked by email about the production time of 1,000 hydraulic needle valves, He specially emphasized that the technical parameters of the hydraulic needle valves need to be the same as those samples made before, especially the valve hole accuracy must be 100% within 1 m or less. Samuel has been cooperating with AAK for 3 years. It is the first time that he deliberately emphasized as such in email. After communication, I learned that the hydraulic needle valves that AAK made samples for last time was 20% higher than that of other hydraulic valve manufacturers, so he placed the order with another manufacturer. However, now this batch of hydraulic needle valves have been complained by customers that the hydraulic winch is stuck. The root cause is that the accuracy of the hydraulic needle valve holes is uneven, and some are less than 1 m, and some higher than 1 m. After the original hydraulic needle valves were replaced by the manufacturer, complaints still continued. The boss was very dissatisfied with Samuel's purchase this time and asked him to source another hydraulic needle valve supplier. Samuel can only get back to AAK, because the sample accuracy of AAK hydraulic needle valve hole was 1 m or less. I told Samuel that the shipment of AAK hydraulic needle valves has never been lower than the sample standard. The next day, Samuel sent us the PO of 1,000 hydraulic needle valves. After 45 days, AAK delivered 1,000 hydraulic needle valves. Last week, Samuel sent an email saying that AAK hydraulic needle valves had been installed on the equipment for more than half a year, and no complaint was received. His boss would rather spend 20% more cost and must purchase the hydraulic needle valves with valve hole accuracy 1 m for 100%. I told him that even if AAK hydraulic needle valve is used properly in another year, it will not get stuck. Samuel was surprised at how AAK ensured 100% accuracy of the hydraulic needle valve hole within 1 m? For the control of the manufacturing quality of hydraulic needle valves, AAK's 3 characteristics lead the majority of hydraulic valve manufacturers. 1. On the processing equipment, the valve hole is finished with the TAMIX one-time tool walking high-speed ultra precision honing mill imported from Japan, which is thoroughly ground without traces. In mass production, the wear-resistant SPA tool effectively ensures the stability of processing, and the valve hole accuracy is guaranteed to be 0.8-1.0 m and the surface roughness reaches Ra0.2-0.3. 2. In the processing process, AAK has more than 10 years of experienced technicians with special machines and special personnel, who have engraved the dimensional accuracy of each element in their minds.

The email from Draper this morning made me in a good mood all day. I had two bowls of rice at noon. He said that 5 months have passed since AAK supplied the hydraulic needle valves in September last year, they have not received any complaints from users. His owner finally accepted his suggestion: "AAK is the preferred supplier for hydraulic needle valves, even if the price is 20% more expensive". Draper, whom we met in 2019, is a purchasing veteran of Doedijns company in the Netherlands. In 2019, he purchased 3 small batches of hydraulic needle valves from AAK in 3 times. He was very satisfied with the quality and service of AAK hydraulic valves, but in the recent two years of 2020 and 2021, he basically just placed orders for the very difficult and small quantity of hydraulic valves. Draper told the truth privately that he couldn't persuade the owner to place a big order with AAK. The problem is the price. Sometimes the price of AAK hydraulic valves is 20% higher than that of other manufacturers. Only the orders that are out of the capacity other hydraulic valve manufacturers will be placed with AAK. Last July, Draper sent us an email with the subject of "the production time of 1200 hydraulic needle valves". Because he had never sent an inquiry for such a big quantity of hydraulic needle valves, I thought that he sent the email to us by mistake. After communication, it was learned that he finally persuaded the owner to place big order with AAK even if the hydraulic needle valve is 20% more expensive, because they don't want to waste time on the after-sales for the hydraulic needle valves. In the past 2 years, customers have complained more and more about the hydraulic needle valves purchased by Draper. The complaints are basically about some small details of the hydraulic needle valves. For example, the hidden burr of the hydraulic needle valves in the hydraulic power system is not completely cleaned, which affects the matching accuracy and assembly of various parts in the system, as well as the tightness of the matching interface, resulting in internal leakage. Some hydraulic needle valves are complained by users after being used for even only 3 months. For many times, they needed to replace the hydraulic needle valves for users with new ones, which wasted too much of time due to after-sales and also interrupted the construction progress of users. The 1200 hydraulic needle valves purchased from AAK this time are the repeat order for their old customer. The customer said that they will not accept the repair of hydraulic power equipment within 6 months for any reason. Draper once again suggested the owner purchase the hydraulic needle valves from AAK, because in the past 3 years, there has never been any abnormal quality of any hydraulic valves purchased from AAK within 12 months.
