Adgar from Russia is an old customer of AAK. Recently, he introduced me a customer named Coko. This should be the 4th time for Adgar to introduce me new customers. Coko’s company has developed a hydraulic power unit for aviation systems, but encountered accuracy issues when purchasing hydraulic cartridge valves. In early March of this year, Coko purchased a high-precision hydraulic cartridge valve from an old supplier. But the equipment debugging was not smooth, and the root cause was that the cylindricity of the hydraulic cartridge valve spool exceeded 0.8µm, while the accuracy also exceeded 4µm. The engineer requested that the cylindricity of the hydraulic cartridge valve spool be controlled within 0.3µm and the accuracy be within 2µm, but the original hydraulic cartridge valve manufacturer gave up. After a week of sourcing, there was no manufacturer who is willing to try. Coko contacted her good friend Adgar, which facilitated the connection between AAK and Coko. According to Coko's description, I know that the machining difficulty of this hydraulic cartridge valve is high, but similar hydraulic cartridge valves produced by AAK, were used on aircraft by Russian customers in 2019. After learning about it, Coko was very happy and requested us to ship 30 hydraulic cartridge valves as soon as possible. Fortunately, we still have stock of this hydraulic cartridge valve, and in about 2 weeks, she received the bulk shipment without any delay in his prototype development. Yesterday, Coko sent us an email to order 500 hydraulic cartridge valves, as their prototype received positive feedback from the customer. Their engineers are very satisfied with the stable manufacturing quality of AAK hydraulic cartridge valves. All 30 hydraulic cartridge valves meet the requirements of spool cylindricity within 0.3µm and the accuracy within 2µm. The level of accuracy not only depends on the manufacturer's awareness of manufacturing quality, the technicians' understanding of quality, but also good equipment. The precision machining of this hydraulic cartridge valve is carried out by AAK using Japan Hasegawa high-precision lathe, with full axis servo drive and no cam. Linear guide rail, ball screw forced automatic lubrication centralized lubricator, can dynamically control the accuracy of processing components. The cyclone milling unit adopts a hollow design, which is not only convenient for operation but also has stable accuracy. The most crucial thing is to use special transmission bearings, which solve the accuracy that most lathes cannot solve, and ensure the cylindricity and accuracy of the hydraulic cartridge valve spool. AAK hydraulic cartridge valve, with a cylindricity of 0.3µm and an accuracy of 2µm, welcome to give it a try!

Rodriguez is a senior purchaser of a hydraulic equipment company in Mexico. The boss is very satisfied with his work. In the second half of last year, they needed to launch a new hydraulic equipment, which needed to use hydraulic relief valves. The boss asked that the procurement cost of the hydraulic relief valves should be reduced by 15% on the premise of ensuring the quality. He contacted the original American hydraulic relief valve manufacturer, and the manufacturer replied that it was impossible. In desperation, he had to find a new manufacturer of hydraulic relief valves. Rodriguez has participated in the Shanghai PTC exhibition and collected some hydraulic relief valve manufacturers, which have great advantages in terms of price. The quotation of some hydraulic relief valve manufacturers is only half of that of American manufacturers, and the quotation of some hydraulic relief valve manufacturers is 60% cheaper than that of American manufacturers. He is a little surprised that there is such a big difference in the quotation of different manufacturers for the same hydraulic relief valve. They began to test the parameters of the hydraulic relief valves from 3 manufacturers, but did not require AAK to send samples, because the price of AAK was 20% - 30% higher than that of other manufacturers. A month later, the hydraulic relief valve samples from the 3 factories were tested and they all failed to meet the indicators of American manufacturers. The pressure of some hydraulic relief valves could not rise within a few days after the equipment was installed. Rodriguez initially screened the manufacturers of hydraulic relief valves and used the 3 factories with low prices. Maybe it proves that Cheapest is the dearest. He changed his strategy and used the hydraulic relief valve manufacturers with relatively high quotation to test the samples. AAK offers the highest price, but it is still about 30% cheaper than American manufacturer. At the same time, AAK promised that the quality could fully match that of American manufacturer. According to the hydraulic relief valve drawings and working condition information provided by Rodriguez, AAK sent the samples of the hydraulic relief valves after 25 days. A month later, Rodriguez sent an email that AAK hydraulic relief valves passed the test, and the parameters were benchmarked with those of the original American manufacturer, and even some details and appearance were visually more exquisite than those of the American manufacturer. He would like to know how AAK makes hydraulic relief valves that surpass American manufacturers? 1、AAK has a high-precision CNC machining center imported from Switzerland and various independent fixtures upgraded and refitted by itself, which eliminates human errors and avoids faults such as stuck valve spool of hydraulic relief valves. 2、AAK adopts the ultrasonic cleaning machine imported from Japan to scrub the solid surface through the vibration of gas bubbles, so as to clean each hydraulic relief valve part for 100% without leaving any residue. 3、AAK test equipment has 5 pressure test benches that of each can be operated independently, and each test area is equipped with professional inspectors, so as to ensure that each hydraulic relief valve is qualified before shipment. AAK hydraulic relief valves, the details can surpass those of American manufacturers. You are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak228

Some peers left a message after seeing the article "making mistakes is either bleeding or death. AAK hydraulic relief valve can't call mistakes as low level mistakes" on AAK hydraulic valve website: does AAK hydraulic valve never make mistakes? This is a good question. To err is human. Not to mention a multi person organization. AAK hydraulic valve can make ignorant mistakes, but it can't make arrogant mistakes. What is the ignorant mistake? I haven't done this before. I don't know how to do it. I found that I made a mistake. If this error occurs in AAK hydraulic valve, we are willing to pay or encourage it. Why encourage mistakes?   1. Because you know you are ignorant, you won't invest too much in it. The cost of making ignorant mistakes is controllable.   2. You are ignorant this time, you will know next time. You will summarize and review. This is the process of learning. AAK hydraulic valve encourages employees to make ignorant mistakes and they grow up quickly.   AAK hydraulic valve can not make arrogant mistakes. What is arrogant mistake?   For example, engineer A said that I know too well about this hydraulic valve. I've been clutching my hand for a long time. It's all experience. Once it's this attitude, it's over. Because of A's arrogance, it's easy to take it for granted to do this hydraulic valve.   In the production process of AAK hydraulic valves, it has always been emphasized that the most grass-roots managers have the final say. I don't want the production director to have too much power, the production boss to have too much power, and the chief engineer to have too much power. Grassroots managers, who are immersed in the specific operating procedures of hydraulic valves, know how to do better than you. AAK senior managers of hydraulic valves discuss with them to provide some experience in the hydraulic valve industry and give them some suggestions.   For example, although I don't operate the hydraulic valves or specific things in the company, I like to make suggestions and ponder. If the suggestion I mentioned, the idea, can inspire them, then use it. If you don't think so, let it go.   In AAK hydraulic valve, if things are not done well, first admit your ignorance and don't be arrogant. What really causes us trouble is not what we don't know, but what we think we know. Only by maintaining a spirit of exploration can it become a biological tissue and grow freely. Only in this way, AAK hydraulic valve can have a future.   AAK hydraulic valve, zero tolerance for arrogant errors. https://www.aakindustry.com/info-de , tail/hydraulic-valves-aak227

Zenon is from a hydraulic equipment company in Mexico. He has purchased hydraulic components from the United States for 4 years smoothly. His boss learned that more and more colleagues are purchasing from China, and also asked Zenon to try to contact China hydraulic valve manufacturers. Unexpectedly, he was stumped when he purchased hydraulic cartridge flow control valves the first time. At the beginning of the year, their company customized a hydraulic lifting equipment for a customer, which required to use hydraulic cartridge flow control valves. Zenon found a hydraulic cartridge valve manufacturer in Ningbo to make samples for the hydraulic cartridge flow control valves. During equipment debugging, the lifting positioning was abnormal. Their engineer judged that the hydraulic cartridge flow control valve was abnormal. After the manufacturer tested the hydraulic cartridge flow control valve, its parameters met the requirements of the drawing. Their engineer asked the manufacturer to further optimize the hydraulic cartridge flow control valve, but the manufacturer was unable to do it. Zenon had to change the manufacturer. After 1 week, no manufacturer was willing to make samples, because there was no direction and great uncertainty. The boss has been pushing, and Zenon was under pressure. Zenon found AAK on Google, stayed on AAK website for more than 7 minutes, noticed that AAK mainly supplies some big brands of hydraulic cartridge valves in the United States. Perhaps he saw the hope from AAK and left a message: 1.Is the hydraulic cartridge flow control valve the root cause of abnormal hydraulic lifting and positioning? 2.Can AAK optimize the hydraulic cartridge flow control valve? 3.How long does it take for AAK to customize the hydraulic cartridge flow control valve? AAK website has messages every day. For such specific and targeted messages, I always give priority to them. After communication, I learned the dilemma of the hydraulic cartridge flow control valves he purchased from the original manufacturer. According to the original design drawings and the video of equipment on-site commissioning, AAK engineers believed that the probability of the problem lies in the control mode of the hydraulic cartridge flow control valve, and we have specific plans to optimize it. Zenon relaxed and asked AAK to make samples. After 30 days, AAK sent 12 samples of hydraulic cartridge flow control valves. 3 weeks later, Zenon said that the equipment debugging was smooth, and the lifting and positioning were normal. The customer was very satisfied with the customized prototype, and would send regular order if there was no abnormality after a trial period. I told Zenon that AAK has confidence on the hydraulic cartridge flow control valves, and can wait patiently for the customer's regular order. We have facts had proved it. For this hydraulic cartridge flow control valve, the valve port flow is not only related to the valve opening area, but also related to the pressure difference before and after the valve port. We use closed loop to control the flow of the valve. First, connect the spring chamber with the non spring chamber through the flow channel, and set the return spring and the valve spool on the same axis, with one end connected to the valve body and the other end connected to the valve spool for valve spool reset. In this way, the flow will not change with the change of load pressure, and the flow of the control system will change with the set value. The advantages of such optimization: accurate control, small pressure loss and flexible operation. Most hydraulic cartridge flow control valves adopt open loop control, which has low control accuracy, complex mechanical structure and large pressure loss. AAK hydraulic cartridge flow control valve has precise control, small pressure loss and flexible operation.

A few days ago, a manufacturer that made parts for AAK hydraulic manifolds, wanted to upgrade its products to do hydraulic manifolds. He came to my office, to ask about the market prospect of hydraulic manifolds, and how to do it well? I told him if he could do hydraulic manifolds, he should ask himself first: 1) Can I do a good job of hydraulic manifolds? That is whether you have this level or skill 2) How to face the competition? That is, whether you have advantages and characteristics, compared with your peers It is popular to invite customers to eat and drink in domestic quotations. In fact, in my opinion, the wine you drink with customers is because you don't sweat when you make products. Do a good job of hydraulic manifolds, starting from 3 points. 1. How to do a good hydraulic manifold? What will I do when I think from my own ability? What can I do? As the saying goes, don't work on porcelain without diamond. Starting from my ability, I think about what I can do. 2. The achievements of technology accumulation are also the method to do a good job of hydraulic manifolds. There is a saying in China that cannons shoot mosquitoes, and cattle knives are used to kill chickens. My feeling is, why do some companies have good products and strong competitiveness? It is because they have accumulated enough ability. When this ability is reused to other places, it is likely to be a dimensionality reduction attack. So don't be surprised when you see a product that makes you feel amazing, because all the overnight fame is the result of silent accumulation. 3. On the other hand, to do a good job of hydraulic manifold, is to start from the pain point of consumers, and what users need. After all, it is really good hydraulic manifolds that can solve users' pain points. So, to solve the problem, we should first analyze the problem. Where does the problem appear? Sometimes it takes a lot of effort to solve a seemingly simple pain point. Focusing on users, and solving users' pain points, is not a lofty slogan, but practical accumulation of technology little by little, which really needs to be done in a down-to-earth manner. Leave simplicity to consumers and complexity to the R&D team. Put your eyes on the consumers, and your heart on the process, test machine and technological breakthrough. Only by mastering the bottom technology of hydraulic manifolds, we can establish the long-term competitiveness of hydraulic manifolds. If you want to make a fully functional hydraulic manifold, you may be able to imitate it. But to make a hydraulic manifold with characteristics and stable performance, we must accumulate technology and innovate. From the perspective of ability, we should constantly accumulate technologies that can be used for reference and find opportunities. From the perspective of demand, we can really solve users' pain points, and provide solutions to problems. Starting from the future, focus on the most advanced processing technology, to achieve breakthroughs and innovation. AAK hydraulic manifold, from the beginning, is to proceed from these 3 points, pragmatic and firm. This is also the reason why AAK has become the hydraulic manifold supplier and manufacturer in China of Fortune 500 Company, listed company in Canada and Israeli military products company https://www.aakindustry.com/info-de , tail/hydraulic-manifolds-aak472

Iscen from Türkiye left a message on the website of the hydraulic cartridge valve manufacturer AAK: What if the valve holes of the hydraulic cartridge valve has burrs? After communication, it was learned that Iscen is a wholesaler of hydraulic cartridge valves, and has been purchasing from hydraulic cartridge valve manufacturers in China for 3 years. They designed a hydraulic cartridge valve themselves, and for every batch of production from the original manufacturer, there were always several customer complaints about burrs in the valve holes of the hydraulic cartridge valves. Although the defective quantity was not large, Iscen was still worried about losing the customer. According to the picture of the hydraulic cartridge valve sent by Iscen, one of the valve holes has a very small diameter, improper drilling can result in residual burrs and difficulty in cleaning. In the early days, hydraulic cartridge valve manufacturer AAK also encountered this type of problem. Our equipment engineer spent more than half a year modifying the equipment based on the Jinlida Drilling Center as a specialized equipment for processing small aperture valve holes. I have a short video I took for an American client a few months ago. At that time, we processed small aperture valve holes using optimized Jinlida drilling center. The tools and drill bits used were customized from Germany and washed with double water pipes. The optimized drilling equipment has 3 advantages: 1.Fast processing: With one clamping process, from cutting, drilling to tapping, the machining is completed in one go, which not only has high efficiency but also avoids human errors. 2.No burrs: The drill bit is magnetic and can automatically remove cutting burrs. 3.High precision: The drilling center adopts a servo control system, which timely controls the position and motion trajectory of the cutting tools. The automatic tool replacement system reduces errors in manual operation and provides accuracy assurance. AAK hydraulic cartridge valve, no burrs or residue, you can also give it a try!

Erop comes from Russia, and started purchasing hydraulic cartridge valves from Ningbo 2 years ago. In the second half of last year, they customized a hydraulic cartridge valve for use in their power unit equipment. After debugging, it was found that the equipment has 3 disadvantages: vibration, high impact, and high energy consumption. Their engineer optimized the hydraulic system, but the customized hydraulic cartridge valve did not work well. After 3 times of revision, the sample still failed to match the equipment requirements, which made Erop very upset. Erop found AAK in B2B, browsed AAK website for more than 5 minutes, and left a message: Can the AAK hydraulic cartridge valve solve the problems of vibration, high impact, and high energy consumption in the hydraulic power unit? This question is too big. It is hard to determine if it can be solved solely by replacing hydraulic cartridge valves. After communication, it was learned that his customized hydraulic cartridge valve was unable to upgrade their equipment. Based on the schematic diagram of the power unit system provided by Erop and the anatomical diagram of the original hydraulic cartridge valve manufacturer, AAK engineers have determined that the valve spool of the original hydraulic cartridge valve is under unbalanced force and is a hidden danger, AAK can make samples to solve the hidden dangers of equipment vibration and impact, but not very certain to solve the energy consumption problem. Erop may not have a better choice, and asked AAK to make samples after a week later. After 45 days, AAK sent out 10 samples of hydraulic cartridge valves. 4 weeks later, Erop informed us that the equipment trial run was successful. Their engineers were very satisfied with the 2 advantages of AAK hydraulic cartridge valves (no vibration, low impact). Their hydraulic power unit energy consumption also decreased by more than 10%. Compared to similar devices in the market, their equipment highlighted 3 major selling points (low vibration, low impact, and energy consumption reduction). The concept of AAK hydraulic cartridge valve is that the original valve spool is in an open state and cannot be closed, which is the root cause of impact and vibration. If the valve spool is closed or opened, a large amount of oil is required, which also leads to high energy consumption. We made clever moves around the valve spool. The force area on both sides of the AAK hydraulic cartridge valve spool is equal and the force is balanced. The valve spool is not affected by pressure, shortening the opening and closing time, and the movement state of the valve spool is easy to adjust and control, reducing impact and vibration, and reducing noise. 1. The valve spool is arranged in the valve chamber of the valve sleeve and can slide. There are axial and radial main oil ports in the front of the valve chamber, and the rear of the valve chamber is separated into a pilot controlled opening chamber and a pilot controlled closing chamber by a convex plate located on the outer side of the rear end of the valve spool. 2. The spring is installed in the spring installation chamber at the rear end of the valve spool, and there is a ring shaped extension at the rear end of the boss, and the outer diameter is smaller than the inner diameter of the valve chamber. The rear end of the valve chamber is fixed with a guide sleeve that allows the ring shaped extension to slide through it. 3. The valve chamber between the boss and the guide sleeve forms a pilot controlled closing chamber. AAK hydraulic cartridge valve, 2 advantages, no vibration, low impact, you can also give it a try!

Consuelo is from Spain, and has purchased hydraulic cartridge valves from AAK 8 times. At the beginning of this year, she inquired about cartridge solenoid valves, and a week later, she reported that the price of AAK solenoid valves was higher than other hydraulic cartridge valve manufacturers in China. Therefore, she did not purchase the solenoid valves from AAK, and I did not ask too much because working with her on hydraulic cartridge valves was also quite good. Last month, she suddenly asked me, 'Is the price of the cartridge solenoid valve that AAK quoted last time still valid?'? After communication, I learned that she encountered difficulties in purchasing cartridge solenoid valves from other hydraulic cartridge valve manufacturers in China. At the beginning of this year, they developed hydraulic manifolds that required the use of cartridge solenoid valve equivalent to HydraForce standard part SV08-20. Consuelo chose a hydraulic cartridge solenoid valve manufacturer in Ningbo to place the order. But now their prototype has been complained by customers that the magnetic sleeve of the cartridge solenoid valve is not securely welded, and some solenoid valve magnetic sleeves have friction with the armature, causing hidden dangers. Consuelo realized that this hydraulic cartridge valve manufacturer was unreliable and came to me. She asked us to ship 100 pcs of cartridge solenoid valves within 40 days, and specially emphasized the welding of the magnetic sleeve of the cartridge solenoid valve to avoid the hidden dangers of friction. I told her, what kind of experience you had with purchasing hydraulic cartridge valves from AAK before, and the same goes for purchasing cartridge solenoid valves from AAK, so there's no need to worry about purchasing cartridge solenoid valves from AAK. I specially made a video for her to understand the difference between AAK and most hydraulic cartridge solenoid valve manufacturers in China. AAK adopts Planck laser welding machine and adopts brazing welding process. It brings 2 benefits to us: firm welding, small deformation, ensuring stable processing accuracy of the magnetic sleeve, and high production efficiency. Most cartridge solenoid valve manufacturers outsource the processing of magnetic sleeves, and generally use argon arc welding technology. The hidden danger is that there is large deformation during welding, and the dimensional accuracy of the magnetic sleeve during processing is not stable, which can easily cause hysteresis of the solenoid valve. At the same time, the welding fastness is also unstable, which can easily cause fracture at the welding point of the magnetic sleeve of the solenoid valve. The manufacturer chosen by Consuelo adopts this process, which not only has poor production efficiency but also brings hidden dangers to customers. AAK cartridge solenoid valve, a new process, brings you 2 major benefits, you can also try it out!

I've been working on hydraulic valves for 13 years, but I never say I've focused on hydraulic valves for 13 years. 13 years of hydraulic valve career, has been adhering to. I think no matter what you do, 10 years is a cycle, because only 10 years of persistence can make some small achievements, but they are only small achievements, which can't catch up with success. There must be compound interest in long-termism, but it does not mean that we should do it mechanically in the 10 years and then wait for the arrival of the cycle moment of the 10 years. It's impossible for me to stick to the industry for 10 years if without orders coming one by one in the daily working time, absolutely not possible. Therefore, long-termism is to produce hydraulic valve orders, while making hydraulic valve innovation at the same time. After 10 years of deliberate learning, pondering and imitating the major brands of international first-line hydraulic valves, we can make some small achievements at the time of the arrival of 10 years. AAK hydraulic valve is not a big brand. I never imitate the words of "lyrical romance" of big brands. Instead, I insist on what benefits AAK hydraulic valve can bring to users, what problems have been solved and what pain points have been solved, that is, the difference of AAK hydraulic valve function and performance from its peers. It has been 13 years since I started my business. 70% of the hydraulic valve customers come from the network and 30% of the customers come from the introduction of these 70% customers. My idea is like this: 1. Never burn money to advertise hydraulic valves. Almost all of them are free promotion at the cost of a lot of time and energy. There seems to be no holiday in a year. I have to work for about 12 hours every day. Because I'm stupid, I can only do a little every day, but I never stop. 2. Focus on the cartridge hydraulic valves, a single large category, which has been used in the hydraulic system in the fields of engineering machinery, agricultural machinery, field exploration and aviation flight. It is positioned for high-end customers who pay attention to quality and never produce the market common quality. 3. For the raw materials and semi-finished products, process and technology, production equipment and production line control of hydraulic valves, I dare not say I am proficient in these 4 parts, but at least at the level of assistant engineer. This is the basic skill and hard work of doing content. 4. Like to output the content of hydraulic valves, write the content that customers want to see and will see, so as to attract real hydraulic valve customers and help customers solve problems, even if they give customers a "so it is". 5. Mindfulness to be a man and to do things. I never believe in the concept of "treat the company as your family", which either cheat employees or cheat yourself. In my understanding, mindfulness is not to cheat, or make small movements under the table. It is not difficult to improve the quality of hydraulic valves, and it is difficult for me to understand why some hydraulic valve manufacturers like producing market goods. As long as the cost of raw materials and semi-finished products is increased by 5 ~ 10%, the quality of hydraulic valves can be greatly improved. I don't know, why can't these bosses change? AAK hydraulic valve adheres to the top 1% of the subdivided market. At the same time, it aims at the global first-line hydraulic valve brands in terms of quality, first benchmarking them, and then surpassing them. With 13 years of long-termism and being the ODM factory of the global top 10 hydraulic valve brands for many years, AAK has been able to surpass the international first-line brands in terms of export quality and price. AAK hydraulic valve, never cheating or doing small movements under the table https://www.aakindustry.com/info-deta , il/hydraulic-valves-aak226

Jone is a hydraulic customer from the United States. His company has recently developed a hydraulic relief valve suitable for machines with high impact and high load. Because of the high requirements of working conditions, the steel used for the hydraulic relief valve has not been approved yet. They have been testing in the local hydraulic relief valve manufacturers in the United States for several weeks. Due to the high cost of proofing in the United States, they want to turn to Chinese hydraulic relief valve manufacturers for sampling and testing. Jone compared more than 10 hydraulic relief valve manufacturers and selected 3 to make samples. After receiving and testing the samples of hydraulic relief valves, none of them can meet the requirements of service conditions, and the test results are much worse than those of local manufacturers in the United States. Although these 3 hydraulic relief valve manufacturers changed the materials and improved the parameters, the toughness and plasticity of the steel still did not meet the working conditions, and Jone and his team were at a loss what to do. His friend Tom recommended him to contact AAK hydraulic valve for a try. Jone sent us an email with a try attitude. According to his hydraulic relief valve drawings and the working conditions with large impact force and high load, our engineers were not 100% sure, but were 90% sure, giving 2-3 weeks. Two weeks later, AAK successfully sent 6 hydraulic relief valve samples. On the 3rd day after Jone received the hydraulic relief valve samples, we received an email that the samples of hydraulic relief valve passed the performance test. AAK spent 2 weeks to try over 10 kinds of steels, and finally determined to replace 40Cr with 35CrMo steel. The high toughness and plasticity parameters of 35CrMo well match the working conditions of this hydraulic relief valve. At the same time, 35CrMo has high static strength, impact toughness and high fatigue limit, and the long-term working temperature can reach 500 ℃. Jone was surprised that the samples of more than 10 hydraulic relief valve manufacturers in China were not successful. Even if the local manufacturers in the United States spent 4 weeks but still failed, how can AAK succeed in 2 weeks one time? The reason why AAK hydraulic relief valves can do what the domestic factories in the United States failed to do, because: 1.AAK has full-time material engineer who is specially responsible for material screening, comparison, testing and docking with the materials research institute. 2.Good materials also need good processing. The heat treatment method adopted by AAK for 35CrMo alloy steel is 845 ℃ annealing, 860 ℃ quenching (oil quenching) and 200 ℃ low temperature tempering. After this special heat treatment, its hardness and wear resistance are increased by at least 50%. 3.AAK technical team has engineers from the global top 10 hydraulic valve industry. They have their own experience in material selection, production drawing design and production line quality control. AAK hydraulic relief valves, high load and high impact resistance, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak225

This morning, I received the order of 2,000 hydraulic needle valves from Charlotte. At first, I thought she sent the email by mistake, because Charlotte had no cooperation with AAK, we just discussed the inquiry for her hydraulic needle valve with pressure resistance of 450bar for 3 times. It is the first time I met a hydraulic valve customer who placed a big order after 3 times of communication. I asked her directly why she gave AAK such a large quantity of hydraulic needle valves order in only the first cooperation. Charlotte said that this hydraulic needle valve was purchased from HAWE in Germany 3 years ago, because HAWE is the best manufacturer of high-pressure hydraulic valves in the world. Charlotte is from a hydraulic equipment company in Spain. Last month, their company tried to purchase this high-pressure hydraulic needle valve from Ningbo, which is the hometown of hydraulic valves in China. She has a hydraulic valve supplier who has cooperated for 5 years and has high mutual trust. Due to the special requirements and urgent delivery date of this hydraulic needle valve, the original hydraulic valve supplier was unable to bear it, so he suggested Charlotte contact AAK, and joked that if AAK could not complete this hydraulic needle valve, she should not waste more time in Ningbo, but go back to HAWE to purchase the high-pressure hydraulic needle valves. I received the drawings and working condition requirements from Charlotte. This customized hydraulic needle valve is applied to aviation equipment. The working condition pressure is required to reach 450bar. It is required to be delivered within 50 days. The quality needs to be comparable to that of HAWE in Germany. Just like Ningbo counterpart said, in Ningbo, there may not be a second manufacturer who is able to produce this high-pressure hydraulic needle valve except AAK hydraulic valve. Charlotte was curious about why the Ningbo counterparts recognized AAK high- pressure hydraulic needle valves so much, and AAK was also so confident in its own high-pressure hydraulic valves. What is the strength of AAK high-pressure hydraulic needle valves? Like horse racing, if you want to win the gold medal, then a good horse should be equipped with a good saddle and a good rider. What are the good horses, saddles and riders of AAK? If you need to meet the following 3 points at the same time, you may not be able to find a second hydraulic valve manufacturer in Ningbo to produce high-pressure hydraulic needle valves, except AAK hydraulic valve. 1. Good horses: AAK has high-precision machine tools imported from Switzerland, Mikron GF high-precision CNC machining center and GILDEMEISTER turn milling composite machining center. 2. Good saddles: AAK has full-time material engineers in material selection, who are specially responsible for screening, comparison, testing and docking with the Research Institute. According to the working conditions of the hydraulic valves, the suitable materials are matched pertinently, not to use the general materials in the market. 3. Good riders: special personnel shall be assigned to operate the special machine in key processes. Only technicians who have worked in the workshop for at least 5 years can take up the post. There are engineers from Shanghai factory of Germany HAWE, who have worked there for 11 years. They know all the production and processing technologies of HAWE factory back to front. They can fully benchmark HAWE factory in terms of material selection, process formulation, production line control, quality inspection and other processes. Charlotte can’t refuse the 3 unique advantages of AAK high-pressure valves and confirmed the PO in 2 days with AAK. A single flower does not make a spring. The improvement of products may not just due to market competition, but also the improvement of the level of the whole industry. AAK leads Ningbo hydraulic valve manufacturers to jointly face the high-pressure hydraulic needle valves. AAK high-pressure hydraulic needle valves are recognized as a leader in the industry by counterparts. Welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak224

How can there be a worldview without observing the world? Whether it's the boss of a hydraulic manifold manufacturer or the management of a hydraulic manifold manufacturer, especially their children, the purpose of studying abroad is not to come back and find a job in the future. If the child of a hydraulic manifold manufacturer simply wants to find a job, there is no need to go abroad. It's better to stay in his hydraulic manifold manufacturer factory and gradually polish into a senior technician. For children of hydraulic manifold manufacturers, studying abroad is not for a diploma or educational background, but for their own career and future development as hydraulic manifold manufacturers. China is doing very well now. The Belt and Road Summit has attracted more than 140 countries (more than 70% of countries), more than 30 international organizations, held an international conference of 4000 elites, signed 711.1 billion yuan (97.2 billion dollars) of cooperation projects, and nearly 300 domestic and foreign entrepreneurs signed on-site contracts in 15 batches, covering 68 countries and regions. Perhaps only China has such a calling power for such a high-level international conference. So, the boss of a hydraulic manifold manufacturer should try to send their children out to study abroad and expand their horizons. If they don't go to see the world, how can they have a worldview? What major do children from hydraulic manifold manufacturers choose to study abroad? 1) International trade. 2) Business. 3) The technology, process, or design related to one's own hydraulic manifold manufacturer. Why not study other majors? 1) Future hydraulic manifold manufacturers will inevitably move towards Industry 4.0, using artificial intelligence equipment. Perhaps 20 years from now, hydraulic manifold manufacturers may no longer need workers in their workshops. 2) In the future where the staff size of hydraulic manifold manufacturers is increasingly shrinking, enterprise management has become simpler, and sales have become the top priority for factories. 3) Especially for a hydraulic manifold manufacturer, online marketing, dissemination, and sales are the only functions that affect the future. Of course, another important task for children to study abroad is to learn English well, especially their oral communication skills, which is difficult to achieve in a Chinese environment, such as learning mute English. Only by integrating into the local society can one master true spoken English. Children studying abroad have 3 major systems of knowledge besides their majors. 1. Choose more underlying disciplines such as mathematics, history, or philosophy, which can enable children from hydraulic manifold manufacturers to have the underlying logical thinking and reach the essence in 3 seconds. 2. Multiple choices in psychology, behavioral economics, and neuroscience are very helpful for the marketing of hydraulic manifold manufacturers, not only understanding what sales are, but also knowing why. 3. Multiple choices in Western classical music, painting, and comparison of Eastern and Western cultures, are helpful for communication between hydraulic manifold manufacturers and Western customers. It doesn't take time, it's still fun, who doesn't love it? I am a person with a background in engineering. After entering society, I have great limitations in thinking and cognition. I hold a scientific attitude towards everything, and often have a single minded mind. It is clearly out of sincerity, but in the end, things go against my wishes, which is really foolish. This foolishness may be due to low emotional intelligence. A low emotional intelligence makes a fool of oneself. Hydraulic manifold manufacturers, whether in business or enterprise, apart from focusing and focusing, the key elements for true success are not technology and craftsmanship, but the 3 major choice systems mentioned above. Never underestimate them. This is a matter of experience. At my age, I should be qualified to say a little bit. Emotional intelligence is not something that can be seen on the surface, such as being able to speak, be funny, or come up with things. Only in social practice can one gradually realize what true emotional intelligence is. Hydraulic manifold manufacturer AAK, a bit silly, but always hold onto the right mindset.

Christopher is from Italian hydraulic company Hydr-app S.p.a. and responsible for the procurement of Beijing office. At the beginning of last month, he wanted to purchase a batch of hydraulic flow control valves urgently from AAK, because they had a batch of hydraulic power units sold to Southeast Asia that needed to replace the hydraulic flow control valves. At the beginning of last year, considering the cost and supply, his boss purchased the hydraulic flow control valves from China, which were originally purchased from Brevini locally. At the beginning, AAK also participated in the sampling of hydraulic flow control valves, but was cancelled because the quotation of AAK was more than 25% higher than that of other hydraulic valve manufacturers. Half a year later, they were complained several times that the hydraulic flow control valve leakage led to the unstable pressure of the hydraulic power unit. The original manufacturer replaced some hydraulic flow control valves, but 6 months later, similar complaints happened again, that is, the stability of these hydraulic flow control valves was only 6 months. Christopher found that the AAK hydraulic flow control valve samples have been normal for more than 1 year, which is as stable as the Brevini hydraulic flow control valves they purchased before. He persuaded the boss to buy from AAK. Although the price was more than 25% higher than other hydraulic valve manufacturers, but it was about 30% cheaper than that of Italy Brevini. More interestingly, the stability of AAK hydraulic flow control valves were not only more than twice that of its peers, but also benchmarked Brevini. Christopher wants to find out why the hydraulic flow control valves of every factory samples are qualified at the beginning. Six months later, except AAK, all other hydraulic flow control valves will leak and affect the stability. The leakage of hydraulic flow control valves after half a year is mostly due to the wear of parts, that is, the unstable surface hardness of materials during heat treatment. Most manufacturers adopt conventional heat treatment, which has advantages in processing cost. How does AAK do it? 1. AAK hydraulic valve has its own heat treatment plant, which can adopt different heat treatment methods in quenching, carburizing and nitriding according to different contents of steel. AAK can achieve the aging temperature of 420 degrees, heat preservation of more than 10H, and can also obtain the material hardness of 65HRC. 2. The core component materials of AAK hydraulic flow control valves use the industry's most advanced EFD Induction Sinac heating power supply for induction heat treatment, with less oxide scale and small deformation. The workpiece is quenched and locally heated accurately to make the surface hardness of each processing element consistent. 3. In the later stage, AAK test the hardness of each part of the hydraulic flow control valves point-to-point. SonoDur3, a Rockwell hardness tester imported from Germany, is used to perform nondestructive testing efficiently and accurately. The Italian customer said that the stability of AAK hydraulic flow control valves was benchmarked with Brevini.

This morning, Mason sent an email asking about the production time of 2,000 hydraulic relief valves, which surprised me. Usually, he just places small trial orders of hydraulic relief valves. He is going to place a large order this time. Mason is a purchaser of BRACEBRIDGE company in Canada. We have known each other for 2 years. After communication, it was learned that a batch of their hydraulic pipe laying rigs had been complained about the frequent leakage in the hydraulic pump since the previous year. The after-sales engineer found that the cavitation was caused by the oil passing through the hydraulic relief valves for a long time, resulting in the pressure loss of the hydraulic cylinder. Mason contacted the original manufacturer of the hydraulic pressure relief valves to find a solution. The manufacturer advised that such a working environment can only replace the hydraulic relief valves with cavitation. The trouble is that the same problem happened again half a year later. The customer was very unhappy with this frequent after-sales, and the boss asked Mason to replace the manufacturer of hydraulic relief valves. Mason told his boss that there is no reliable manufacturer of hydraulic relief valves to replace the present one. For the sake of safety, AAK hydraulic relief valves should be selected. Because there was equipment installed with AAK hydraulic relief valves when testing samples at the beginning. Now 1 year later, there is still no cavitation on AAK hydraulic relief valves. But the price of AAK hydraulic relief valve was 17% higher than that of other manufacturers and was not selected. The boss rejected again and asked Mason to find a new manufacturer of hydraulic relief valves. During the continuous screening process, Mason selected 3 hydraulic relief valve manufacturers to test samples. Basically, after half an year, these hydraulic relief valve samples successively had similar faults. Mason was at a loss what to do. He once again suggested to his boss to purchase AAK hydraulic relief valves. After comparing so many hydraulic relief valve manufacturers, none of their samples can be used for more than 1 year under this working condition. In this way, the hydraulic relief valves need to be replaced every 6 months for after-sales. Not only the after-sales cost is high, but the customer is also not satisfied. The boss seems lost faith completely in other hydraulic relief valve manufacturers and agreed with Mason to regard AAK as their preferred supplier of hydraulic relief valves. It took Mason 2 years to persuade his boss to choose AAK hydraulic relief valves with 17% higher price, because he knows that the durability of AAK hydraulic relief valves is at least twice that of other manufacturers. Under complex working conditions, how does AAK ensure that the hydraulic relief valves have no cavitation and its durability is more than twice that of other manufacturers? 1. AAK hydraulic relief valve sleeve orifice processing, the opening adopts conical hole, not cylindrical hole of other manufacturers. Most hydraulic relief valve manufacturers do not have this ability to process conical hole. 2. The chamfering, deburring and polishing process is added at the orifice to further optimize the control edge, so as to reduce the cavitation caused by the flowing oil, and at least eliminate the cavitation within 2 years. Most hydraulic relief valve manufacturers did not expect that AAK has such a unique skill. 3. Devils are in the details. Most hydraulic relief valve manufacturers will ignore small details. Even if some factories think of them, they can't control the technology. AAK hydraulic relief valves, pay attention to every small detail, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak222
