Whether it's a hydraulic cartridge valve manufacturer or other manufacturers, there are always competitors who see you as their competitor. What should be done when a hydraulic cartridge valve manufacturer encounters face-to-face provocation from an opponent and the customer is present? A few days ago, a Russian old customer visited hydraulic cartridge valve manufacturer AAK. After the meeting, he asked me to take him to another hydraulic cartridge valve manufacturer. After arriving at the factory of the another hydraulic cartridge valve manufacturer, I waited downstairs. One hour later, the other party's boss accompanied the customer to the car, and we were ready to leave. When the other party's boss saw that it was me, he said to the customer: It's time for dinner and I’d like to invite both of you to have a meal together. The customer didn't say anything and looked at me. The problem is that competitors invite you to dinner. Are you going or not? 90% of the hydraulic cartridge valve manufacturers would said NO, but I promised to dinner together. Everyone is hungry, and I will pay in advance and make the other party owe me a favor. At that time, I asked him where to have the dinner? I drive, one car is enough. The other party said to go to a five-star hotel, and added, "You've never taken a client to such a high-end place, have you?". As soon as I heard it, the fire started to ignite, but I quickly calmed down. I said that according to the personal preferences of our clients, going to that place for dinner is not very interesting. Today, you come with me. I know there is a private customized small courtyard, and many times, even if you pay, you may not be able to have a dinner. It must be a VIP with more than 3 years of experience. During the meal, that hydraulic cartridge valve manufacturer did not give up and continued to provoke. He asked me suddenly, how is engineer Mr. Liu going on in your factory? I asked what happened. He said that Liu was an employee who was laid off by their factory, and added another sentence, “AAK took over the employee who were laid off by us.”. The customer also looked at me, and I casually said, "You need to reflect on this. Such an excellent talent cannot be retained by your factory. You need to consider your own system and process of the hydraulic cartridge valve manufacturer. Where the problem is?". In the face of provocation, how to solve it, I think it's very simple. Just use "pick it up" and he says no matter how bad you are, you can pick it up. The higher you praise, the more embarrassing the other person will fall. Dealing with provocations from competitors, it is the worst for a hydraulic cartridge valve manufacturer to argue with them.

Last week Grossman placed an order for 1,500 hydraulic cartridge valves at one time. I'm not surprised at all. At the Shanghai PTC exhibition the year before last, I met Grossman from a Russian company and talked for more than 30 minutes at the exhibition. After the exhibition, Grossman informed by email that a newly developed hydraulic equipment of their company needs hydraulic cartridge valves, and 20 hydraulic cartridge valves from AAK were tested. This is a non- standard customized hydraulic cartridge valve. After we delivered the goods, Grossman didn't send any email to feed back the situation of AAK goods for half a year. A year later, Grossman placed the reorder of 200 hydraulic cartridge valves of the same model, and there was also no news after delivery. In 2 years, there were only two small orders of hydraulic cartridge valves, but I have a feeling that Grossman is further deeply testing AAK hydraulic cartridge valves. It was not until last week when there was a large order for hydraulic cartridge valves placed, Grossman then started to describe the ups and downs of purchasing hydraulic cartridge valves in Ningbo. In the past 2 years, Grossman found more than 20 hydraulic cartridge valve manufacturers for sample testing and was cheated by some new hydraulic cartridge valve manufacturers. The quality of the test order was OK, but the reorder was complained by customer. For hydraulic cartridge valves purchased from some other factories, there were always complaints after a period of time, such as several leaks or jamming, insensitive opening and closing or serious wear etc. The 2 batches of hydraulic cartridge valves from AAK have not received any complaint in 2 years, which is why he decided to order large quantities of hydraulic cartridge valves from AAK. After 2 years of comparison among more than 20 hydraulic valve manufacturers, Grossman found that only AAK hydraulic cartridge valves are 100% qualified. His boss also agreed that the future hydraulic cartridge valves will only be purchased from AAK. No customer complaints with AAK hydraulic cartridge valves, that is because AAK has 3 advantages. There may be no second manufacturer in Ningbo who can have the following 3 points at the same time. 1.AAK hydraulic valve has high-precision CNC machining centers, machine tools and other equipment imported from Switzerland, as well as various independent fixtures upgraded and refitted by himself, which eliminates human errors. At the same time, the management of every detail of the processing, production, assembly, inspection and packaging of each hydraulic cartridge valve has been accurately controlled. 2. AAK uses pneumatic measuring instrument to test the accuracy of each processed valve sleeve, while most manufacturers use sampling test. During the assembly of accessories, the accuracy of the fit clearance between each valve spool and valve sleeve is tested again with a pneumatic measuring instrument. 3. After assembly, carefully check whether the accessories are complete, and test each hydraulic cartridge valve, including leakage, flexibility, opening and closing performance etc. AAK hydraulic cartridge valves have conquered Russian customer with 3 facts leading domestic peers. You can also try one order. https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-valves-aak237

Richard, a hydraulic customer from Bolivia, failed to purchase hydraulic cartridge relief valves from China for the first time. Richard has purchased hydraulic components from local hydraulic cartridge valve manufacturers in Bolivia for 3 years. He heard from his peers that the cost performance of purchasing from China is better than that of Bolivian hydraulic valve manufacturers, so he began his overseas procurement trip. A hydraulic cartridge relief valve with rated pressure exceeding 30MPa, and the fit clearance between valve body and valve spool is required to be 0.006~0.01mm. Richard successively tried samples with 3 hydraulic cartridge relief valve manufacturers in 70 days. The hydraulic cartridge relief valve samples had either internal and external leakage, blocked oil circuit, or even stuck. 3 times of proofing failed, which made Richard helpless and even suspected that he was misled by his domestic peers. Richard noticed AAK on the B2B website and saw some tweets and customer cases to solve the problems of hydraulic cartridge valves, especially some big brands such as HydraForce and SUN Hydraulics, are also loyal customers of AAK for many years. He seemed to see hope and left a message to us: How much MPa can the rated pressure of the hydraulic cartridge relief valve with a clearance of 0.006~0.01mm between the valve body and the valve spool be? When I saw this message, I subconsciously felt that he had stumbled in the accuracy when purchasing this hydraulic cartridge relief valve, and he was inexperienced in choosing the hydraulic cartridge valve manufacturer. According to the problems of his hydraulic cartridge relief valve samples, AAK technical team determined that the problem was caused by burrs inside the hydraulic cartridge relief valve. However, the specific problem still depends on the sample analysis. I suggested Richard making samples directly to see the manufacturing quality of AAK hydraulic relief valves. Maybe that will change his view on China hydraulic cartridge valve manufacturers. After 30 days, AAK sent 10 samples of hydraulic cartridge relief valve. 6 months later, Richard emailed us that AAK hydraulic cartridge relief valves did not have the problems of "internal and external leakage, or blockage of the oil path or stagnation" that occurred in other hydraulic cartridge valve manufacturers, which also strengthened his confidence in purchasing from China hydraulic cartridge valve manufacturers. How to effectively avoid burrs of hydraulic cartridge relief valves? It is also a "thorn" that AAK has to remove since it was engaged in the R&D and manufacturing of hydraulic components. With 13 years of manufacturing experience, AAK can be sensitive to find problems and solve them. In the processing of hydraulic cartridge relief valves, the undercut of the main valve hole is the place where the most burrs are generated. The traditional processing technology is: first rough boring, then semi fine boring, then milling the undercut, and finally reaming. The burr generated after reaming is in the same direction as the axis line of the hole, and is sunk in the undercut, which is difficult to remove completely. AAK has already optimized the process route: first rough boring, then semi fine boring, then reaming, and finally milling and sinking the groove. The burr generated is perpendicular to the axis line, and there is no dead angle, which is easy to observe and remove. AAK hydraulic cartridge relief valve, no burr, no leakage, no clamping stagnation, welcome to try the order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak406

This Monday, we launched a solenoid proportional valve equivalent to HydraForce standard part SP08-21. The features of this solenoid proportional valve: Continuous-duty rated coil. Efficient wet-armature construction. Optional waterproof E-Coils rated up to IP69K. Industry common cavity. Compact Size. The function of this solenoid proportional valve: A solenoid-operated, 2 port, normally open, poppet type proportional, screw in hydraulic cartridge valve designed for low leakage in load-holding applications. When de-engergized, the SP08-21 allows flow from 2 to 1. Flow from 1 to 2 is severely restricted. When the valve is partially energized (see performance curve) the valve begins to throttle flow from 2 to 1. When fully energized, the valves poppet closes on the seat, blocking flow from 2 to 1. The cartridge will allow 1 to 2 flow after overcoming the solenoid force. AAK has received 5 inquiries for this solenoid proportional valve within only 3 months, from May to July 2023, with 3 customers placed trial orders. This hydraulic solenoid proportional valve is not only widely used, but also has multiple functions, especially its good performance. Although some China hydraulic cartridge valve manufacturers can produce this hydraulic solenoid proportional valve, and its functions may also be compared to HydraForce standard part SP08-21, their solenoid proportional valve performance may be a problem. AAK hydraulic cartridge solenoid proportional valve 2 advantages: 1. Internal leakage: 5 drops/min, benchmarking against HydraForce 2. Its service life is 2 times that of its peers Technical parameters of AAK E-SP08-21 Hydraulic Solenoid Proportional Cartridge Valve: Max. Operating Pressure: 207 bar (3000 psi) Flow: See PRESSURE DROP VS.

Early March this year, Austin from Canada left a message on AAK website: AAK hydraulic valves have been used in aviation field, can you produce hydraulic relief valves with the valve body produced by nickel titanium alloy? For similar messages, I basically reply that if there is a need, I will directly sampling the hydraulic relief valves. Whether it can meet the standard is not determined by mouth, but by data. After communication, it was learned that their company has a power unit used in the aviation hydraulic system, and the customer requires that the test run be completed within 3 months. Austin contacted an old supplier of hydraulic relief valves with the best quality, and the supplier promised to deliver 20 samples of high-precision hydraulic relief valves within 40 days. After 20 days, the manufacturer of the hydraulic relief valves can't bear it. In particular, the valve body of the hydraulic relief valves is made of nickel titanium alloy. During processing, the cutting tools were changed for 5 times, and 80% of the products were still scrapped. Austin had to find a new manufacturer of hydraulic relief valves. He contacted some new manufacturers in a few days, they either have no confidence in the hydraulic relief valves used in the aviation field, or no reply at all. Austin saw in Google that AAK hydraulic valve supplied to military enterprises and aerospace equipment, and realized that maybe AAK can help solve the dilemma of hydraulic relief valves. According to the hydraulic relief valve drawings and working condition requirements emailed by Justin, AAK engineers found that this hydraulic relief valve is just similar to the one supplied to Russian customer last year. The difference is the valve hole size. It only needs to make small modifications to the process procedure, and 20 hydraulic relief valve samples are sent out after 15 days. Two months later, Austin informed by email that the commissioning of the equipment was very smooth with the use of AAK hydraulic relief valves. AAK was the only one of more than 10 hydraulic relief valve manufacturers he contacted, who dared to make samples directly and completed the non-standard hydraulic relief valves in 2 weeks. Their engineers were surprised to have such a magical hydraulic relief valve manufacturer. The non-standard hydraulic valves were completed in 2 weeks, which most hydraulic valve manufacturers can't do unless there are similar procedures. AAK has a number of non-standard hydraulic valve procedures. The key reason why AAK hydraulic relief valves can be supplied to military enterprises and aerospace fields is the following 3 points. There may not be a second hydraulic relief valve manufacturer in Ningbo that can meet the 3 points at the same time. 1. AAK technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in material selection, production drawing design, oil circuit design and production quality control. 2. AAK has a high-precision CNC machining center imported from Switzerland and Kennametal combined tool imported from the United States. This tool has the best cutting ability for NiTi alloy with very high toughness and strength, and has high advantages in life, performance, efficiency and stability. 3. AAK test equipment has 5 pressure test benches that can operate independently of each other, and each test area is equipped with professional inspectors, so as to ensure that each hydraulic relief valve is qualified before shipment. AAK high precision hydraulic relief valves can be used in aviation hydraulic system. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak236

Recently, I wasn't sure if I was getting older or if I was under a lot of pressure from 3 clients who had ordered hydraulic manifolds at the same time. I had nightmares almost every day, and the sleep quality was always poor. Only taking sleeping pills could solve the problem, but long-term use of sleeping pills had side effects, so after taking them for a few weeks, I gave up. Engaging in hydraulic manifold design and production is indeed tiring. I tried to analyze the reasons why I had nightmares. Was it because of the pandemic last time that a large number of hydraulic manifolds were delayed, creating a psychological shadow? I have consulted a psychologist for psychological analysis and wanted to delve deeper into the meaning of dreams. I have contacted two psychologists, but they still haven't solved the problem and it has become even more serious. Afterwards, I reviewed my consulting ideas: the common sense among the public is that dreams come from contemplation, and endless analysis of the causes of dreams is like throwing oil to fight fires. Psychologists consult based on this common sense, so it's even more serious. My approach is to just solve problems, don't just think about getting things done in one step, take your time and improve step by step. If you can't sleep well every day for 7 days a week, then choose to take sleeping pills for 2 days first. This way, you can sleep well for 2 days. This not only avoids the side effects of taking medication every day, but also benefits from sleeping well for 2 days, which turns into 5 days a week without sleeping well. By changing the sleeping environment, such as the hardness of the bed, the height of the pillow, the orientation of the sleep, the indoor odor, the strength of the lights, soaking feet before bedtime, and massaging the entire body with a massage chair, it was found that soaking feet before bedtime improved sleep, resulting in only 4 days of poor sleep. Trying to exercise 2 hours before bedtime, such as running, shifting gears, basketball, and swimming, only to find that it's just physical fatigue that makes you tired. Doing tiring exercise twice a week can turn into only 2 days of sleep deprivation. From the situation of "not sleeping well every day" to the effect of "not sleeping well 1 or 2 days a week", the sleep problem has been solved for at least half of the time! This inspires me that when the problem arises, we should not daydream there. We must implement in action, and the concretization of the action is the right thing to do. The same applies to the innovation of AAK hydraulic manifolds. 1.AAK hydraulic manifold, do not invent, do not innovate comprehensively, only innovate locally in hydraulic manifolds. 2.The innovation of AAK hydraulic manifolds, focusing on functions, has one more function than peers, and can be promoted to the market. 3.The innovation of AAK hydraulic manifolds, focusing on performance, has a lifespan of over 20% longer than that of its peers, and can be promoted to the market. AAK hydraulic manifolds, slow heart, fast hands, 3 innovative principles, focusing on the manufacturing quality, function, and performance of hydraulic manifolds.

Last week, Beck from the United States sent an inquiry to hydraulic cartridge valve manufacturer AAK, with one only sentence: Please provide a quote for 1000 units based on attached drawings. Hydraulic cartridge valve manufacturer AAK did not provide a quote on the same day, but instead provided Beck with more information about hydraulic cartridge valve manufacturer AAK. Beck only replied with two words: Please quote. I feel like Beck is an engineer and a bit of cool. The day after we quoted the price, Beck directly sent the PO to the hydraulic cartridge valve manufacturer AAK. Such a fast ordering speed is rare, and I was worried about the price being quoted incorrectly. I double checked the quote immediately. AAK's price is correct, and I finally breathed a sigh of relief in my heart. I emailed Beck: you place an order in such a hurry, have you encountered any difficulties in purchasing from other hydraulic cartridge valve manufacturers? Beck's response is still simple: I have been following hydraulic cartridge valve manufacturer AAK for a long time, and I believe AAK is reliable. When the need from my client came out, I placed an order with AAK. A simple yet touching answer, reliable. I think the customer's evaluation of hydraulic cartridge valve manufacturers is reliable, and this is the highest evaluation. For example, hydraulic cartridge valve manufacturers always hope to find "reliable" talents to join the team. From selecting, educating, employing, and retaining people, I always consider "reliability" as the only criterion. Steve Jobs once said that an excellent employee can withstand 50 mediocre employees. Even more than that. And these excellent employees are usually 5% of the population. These 5% cannot be nurtured by "nurturing". We can only rely on "selection". Similarly, if customers want to find a reliable hydraulic cartridge valve manufacturer, they can only rely on selection. What is reliability? The hydraulic cartridge valve manufacturer AAK understands it as follows: reliable, with 4 levels of achievement: receiving and doing, speaking and doing, thinking and doing, knowing and doing. AAK has gone from selecting reliable people, enhancing team awareness, achieving customer requirements, to selecting high-quality customers, making AAK a truly reliable supplier. Hydraulic cartridge valve manufacturer AAK, with its reliable quadruple realm, aims to become a reliable person and do reliable things.

We have an old hydraulic valve customer in South America. He has only two hydraulic valve suppliers in Ningbo, one is AAK hydraulic valve and another one is some hydraulic valve manufacturer. According to his description, AAK accounts for 70% of his purchase of hydraulic valves in Ningbo. In fact, I am very satisfied with this share and will not strive for 80% or 100%. Let him always use AAK hydraulic valves to compare with other hydraulic valve manufacturers, and feel the advantages of AAK hydraulic valves at all times. Recently, He had a brainwave and wanted to purchase all hydraulic valves in one factory. In his email, he asked AAK to give some feedback on the quality positioning, industry reputation and price performance of another hydraulic valve manufacturer. To be honest, this request is very difficult for us, because as a mature hydraulic valve manufacturer, I am unwilling to answer such questions. Before answering this question, what is the sign of personal maturity? There is a good word called "suspended judgment". To put it bluntly, we are not in a hurry to stand in line. Let's see, hang up the judgment we should have first and don't let the boots fall to the ground. When a man is mature and faces any situation, he takes many factors into account. There is no simple right and wrong in his world. In today's digital age, we always try to turn people's vague attitude into a clear number. You have to give “likes” and “dislikes”, either fans or passers-by. In this context, most people's personality maturity slows down and is digitally trained to be eager to make a statement. Under the digitization, for those who are not easy to express their position, such people are out of the control of digitization. Such people are not only mature, but also have more advantages. AAK hydraulic valve only sticks to its own research and development, technical transformation, quality control and service, and never pays attention to the trend of local hydraulic valve peers. I don't know his quality, reputation and price. In fact, I don't want to know. Because I never pay attention to the hydraulic valve counterparts, and only focus on the international first-line hydraulic valve brands. AAK hydraulic valve, never commenting on its peers, only targets the international first-line hydraulic valve brands, and gradually surpasses those international brands. In particular, AAK quality is rooted in the top 1% of the subdivided field of hydraulic valves. AAK hydraulic valve, only go the right way, never afraid to go long way. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak235

Clinton, from Mexico, has purchased hydraulic valves from China for 6 years, and has cooperated with AAK in several non-standard hydraulic cartridge valves. Some time ago, some customers complained that their logistics transmission equipment was not easy to operate. After the after-sales inspection, it was found that the hydraulic cartridge relief valve on the rotary device failed to buffer and the pressure regulation was not smooth. The original manufacturer said that this hydraulic cartridge relief valve was benchmarked to the standard parts of HydraForce, and he was unable to optimize. Clinton contacted me and asked me how to make the hydraulic cartridge relief valve easy to adjust pressure and have buffering function. According to the hydraulic schematic diagram and the original hydraulic cartridge relief valve drawing provided, AAK engineer found that the requirements can be met as long as the original structure is improved. After 35 days, AAK sent 20 samples of hydraulic cartridge relief valves. Last week, Clinton sent a PO for 200 hydraulic cartridge relief valves. He said that when AAK hydraulic cartridge relief valve was installed, the customer no longer complained. It not only provided convenient pressure regulation and effective buffering, but also improved the stability of the equipment. They planned to replace the whole batch of equipment with AAK hydraulic cartridge relief valves. AAK hydraulic cartridge relief valve, the spool, buffer piston and pressure regulating valve housing cooperate to achieve buffer overflow effect, and the overall performance is reliable and stable, mainly from 3 unique structures: 1. The valve housing is provided with a first oil port, and the valve seat is provided with a second oil port. The valve spool can move axially, and the front end cooperates with the rear port of the valve seat to control the on-off between the second oil port and the first oil port. The channel port in the front end of the valve spool is provided with a plug, and the plug is axially provided with a damping hole. The front end face of the valve spool is equipped with a filter screen, and the front pressure surface of the valve spool is larger than the rear pressure surface. 2. The inner cavity of the front end of the pressure regulating screw nut has a buffer piston, and the rear end has a guide part. The radial bulge in the middle forms a convex ring part. The axial opening in the front end matches with the rear end of the valve spool. The oil supply in the middle of the convex ring part is with the connecting channel outside the rear end. 3. The pressure regulating screw is hollow at the rear end of the valve spool to form an inner cavity, which can move axially and change the axial force of the spring. The inner cavity wall of the front end of the pressure regulating screw is matched with the front end face of the convex ring to limit the buffer piston to move forward. For the optimized hydraulic cartridge relief valve, when the pressure at the second oil port rises instantaneously, the valve spool opens the overflow valve, so that the opening pressure of the valve is low, and the oil flows from the second oil port to the first oil port and fills the valve cavity. The oil in the inner chamber flows into the inner chamber of the buffer piston through the damping hole. If the pressure in the inner chamber of the buffer piston increases, the valve spool can be closed to generate secondary pressure, and the valve spool can be opened to overflow again to realize the buffer overflow function. AAK hydraulic cartridge relief valve, has buffer and is easy to operate. You can also try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak475

Dante is from a hydraulic manufacturing company in Greece. In the first half of last year, they wanted to upgrade the lifting stability of the company's original elevator. The function of the hydraulic cartridge counterbalance valve is the key. Dante made samples from a local hydraulic cartridge valve manufacturer that has been cooperating for 5 years. The stability has not reached the assumption of upgrading. After 2 times of improvements, the effect is still not obvious. Dante contacted more than 10 hydraulic cartridge valve manufacturers, but failed after a week. The boss urged the progress many times, and Dante was worried. Dante found AAK on Google, noticed that AAK had some customer cases about hydraulic cartridge counterbalance valves, and sent an email asking: Can AAK hydraulic cartridge counterbalance valve achieve fast start and stable positioning? After communication, we learned that they wanted to upgrade the equipment, and the key selling points of the equipment is to be started quickly and positioned steadily. According to the hydraulic system schematic diagram and the original hydraulic cartridge counterbalance valve drawing provided by Dante, after discussion, AAK engineers confirmed that the original hydraulic cartridge counterbalance valve can be optimized to achieve fast start and stable positioning. After 45 days, AAK sent 10 samples of hydraulic cartridge counterbalance valves.   2 months later, Dante sent an email saying that their engineers were satisfied with the function of AAK hydraulic cartridge counterbalance valve, which realized their lift selling points. Their sales team was confident to do a good job in market promotion and achieve the hot sale of equipment. AAK hydraulic cartridge counterbalance valve can solve the contradiction between response speed and stability, and has no back pressure effect. On the basis of the original, it has made 3 unique optimizations:   1. A fixed damping is installed between the inlet of the hydraulic cartridge counterbalance valve and the pilot oil port. The oil inlet of the valve body is 2 connecting ports of the oil circuit, and is equipped with a pressure gauge interface.   2. The valve spool of the hydraulic cartridge counterbalance valve slides in the upper and middle part of the valve body. The middle section of the valve spool has an inner concave ring, which is the inlet of the hydraulic cartridge counterbalance valve. The right end of the inner concave ring of the valve spool is processed into a conical surface. The conical surface is equipped with a two-stage stepped taper ring. The cumulative area of the conical surface is the same as the area of the cylinder end face at the right end of the valve spool. The stepped taper is adopted to realize the smooth flow change and smooth movement of the hydraulic cartridge counterbalance valve.   3. The cylindrical outer circle at the right end of the valve spool of the hydraulic cartridge counterbalance valve slides with the middle hole of the valve body. The adjusting screw is installed at the top pressure of the rear end of the balance adjusting spring. The adjusting screw is matched with the rear end of the valve body and controls the telescopic operation of the balance adjusting spring.   The optimized hydraulic cartridge counterbalance valve adopts the hydraulic control automatic closing valve to realize the unity of quickness and stability of the hydraulic cartridge counterbalance valve. At the same time, the pressure compensation is used to make the safety overflow function of the hydraulic cartridge counterbalance valve not affected by the back pressure. It can be applied to the hydraulic system with closed center and open center.   AAK hydraulic cartridge counterbalance valve, fast start, stable positioning, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-counterbalance-valves-aak474

A few days ago, I saw a video of Faye Wong's speech. She is a well-known singer in China. When she received an award, she spoke in this way, which roughly means: I know I sing very well myself, thank you for the recognition of my singing skills by the organizing committee, and I also acknowledge their appreciation level. Upon hearing this, I feel the same way. When hydraulic cartridge valve manufacturer AAK receives the first inquiry from a new customer, I always inform them that AAK has supplied 3 Fortune 500 companies. Thank you for your inquiry for hydraulic cartridge valve manufacturer AAK. I admire your vision in choosing AAK and believe that you are different from other customers, especially in terms of manufacturing quality. Why does Faye Wong sing well? Because she no longer needs to prove herself, let alone care about others will say good or bad about what she sings, and she only focuses on understanding the song and immersing herself in emotions. Singing is a pleasure for her. Such a confident person's voice is destined to be like a heavenly sound. If a person is not sure about her profession, I believe her profession must be flawed! If a manufacturer of hydraulic cartridge valves is unsure of his manufacturing quality, I believe that the manufacturing quality of the manufacturer is unstable. The charm of confidence is unstoppable. A confident hydraulic cartridge valve manufacturer brings customers a sense of security and trust. Perhaps there is someone else who dislikes Faye Wong's "unwavering" attitude and criticizes her, but never conceals the brilliance of such "superstars", making "white jade with slight flaws" more authentic. This world will instinctively accept the temper of the strong and call it personality. If there is no top-notch professional competence and confidence, it can only be criticized as arrogance. To put it plainly: Insolence requires capital! The insolence of a hydraulic cartridge valve manufacturer lies in its stable manufacturing quality; It's because other hydraulic cartridge valve manufacturers cannot do it, and he mass-produced it a few years ago; It's because other hydraulic cartridge valve manufacturers are competing for prices, while he is competing for technological upgrades. I really don't like people who like to label people. Just judging a person by their words is humble or insolent, and completely ignoring his strength. Note: Some people are humble because they have self-awareness. And some people are insolent; he's just telling the truth. Hydraulic cartridge valve manufacturer AAK in China is a bit insolent in terms of manufacturing quality, and maintains humility in dealing with people.

Someone asked me, you are not a mechanical professional. How can you guide AAK engineers to solve some difficult and complicated problems of hydraulic valves? Now the hydraulic valve industry has entered the stage of vertical specialization. Unprofessional may be a problem. Although specialization is the standard way to professional knowledge, it may not be a good thing from the perspective of creativity. Because sometimes professional knowledge is a double-edged sword. If you are too professional in hydraulic valves and have too much professional knowledge of hydraulic valves, you may not notice those distant associations. I have always insisted that the solution to the problem is to cast a big net first. Sitting next to the computer at 4:30 in the morning, I have 3 hours of association and quiet time. This is the darkness that does not belong to anyone. People usually wake up at 7:30, I have enough calm and patience to associate with the hydraulic valves and daydream at will. To do something creative, many people say that we should jump out of the box and think, but I think we should do the opposite and learn to think in the box. I often advise my engineers not to create the function of hydraulic valves by imagination, but to innovate on a certain basis of hydraulic valves. Ten years ago, we bought some representative hydraulic valve standard parts and some novel non-standard hydraulic valves from the top 10 hydraulic valve manufacturers in the world from the United States and Europe, comprehensively dissected these big brand hydraulic valves, refined the selling points of technical parameters, and then innovated on these basis. Only then did we have 3 domestic patents and processes and 4 proprietary technologies of AAK hydraulic valves, and AAK hydraulic valves were exported to more than 20 countries, 6 international first-line brand customers have placed orders for 5 consecutive years, and re-buy rate of AAK hydraulic valves from old customers is no less than 62% every year. What you think is right and what you can accept is basically wrong. What you think is wrong and what you can't accept are basically right. I read about 30 pages of books that are not related to the hydraulic valves every day. In the process of reading, I set aside a little time for daydreaming. For example, an idea in the book aroused my curiosity. I need to pause to connect my brain with this curiosity. Sometimes my brain will unconsciously link to the hydraulic valves. Every coin has two sides, depending on the angle we look at. For a half a glass of water, what some people see is: Alas, there's only half a glass of water left; What some people see is: Wow, still have half a glass of water. Pessimists are often right. I admire the pessimists' comments on the real world. Really, they are right, but most of them are losers. Simple minded optimists may not succeed, but they often live a good life. When I encountered the problem of hydraulic valves and couldn't find the answer after thinking hard, I found that sitting at my desk was almost a waste of time. Write out the hydraulic valve problem and knock it in the computer document, preferably on paper. Many people don't write it out, but trap the problem in their brain, which may not awaken their subconscious mind. Then, I will stay away from this hydraulic valve problem. Sometimes, when taking a bath or walking, the rudiment of the answer may come to mind. It's so wonderful. Turn off the music, stay away from the mobile phone, stay away from distractions, and let the brain unconsciously look for associations between different ideas. There may be surprises. Insist on getting up early, reading and exercising, because if you can't persevere, you won't get anything. Those who have not been engaged in the production of hydraulic valves for more than 10 years can hardly have a comprehensive understanding of hydraulic valves. Both enterprises and individuals should stick to their commitments to others, especially to themselves. I have no confidence in anything readily available, improvised and fast, but I believe in the power of stability, peace and long-term flow. Still water runs long. Any hydraulic valve manufacturer should be practical. I never believe that hydraulic valve manufacturers who lack self-discipline and self-growth will have a beautiful future. For example, in life, talented people are easy to bring traffic, but can't bring trust. The builder of self-discipline may not surprise people in a short time, but will gain long-term respect. This may be the cornerstone of trust. AAK hydraulic valves, no trickery, only daily self-discipline construction. https://www.aakindustry.com/i , nfo-detail/hydraulic-valves-aak234

After we posted the last article,“For hydraulic cartridge valves with high requirements, AAK produces them using 5-axis CNC machine tools, someone left a message: Can AAK use a 5-axis machining center to process hydraulic manifold blocks? From the IP, it should be a customer from Russia. Most hydraulic manifold manufacturers do not use this sophisticated equipment to produce hydraulic manifold blocks. How does hydraulic manifold manufacturer AAK use a 5-axis machining center to process hydraulic manifold blocks? Most hydraulic manifold manufacturers use domestically produced or Taiwanese machining centers for their hydraulic manifold blocks, because the accuracy requirements for most hydraulic manifold blocks are not high, and 5-axis machining centers are also expensive. Not every hydraulic manifold manufacturer can have a 5-axis machining center. Why this Russian customer requires a hydraulic manifold manufacturer to use a 5-axis machining center to process hydraulic manifolds blocks? He is likely to have encountered trouble with the valve hole accuracy of the hydraulic manifold blocks not meeting the standard. The higher accuracy the hydraulic manifold blocks require, the more they need to be machined on a 5-axis machining center. Today, the hydraulic manifold manufacturer AAK workshop was processing hydraulic manifold blocks on site, and I took a video for the processing. From the video, it can be seen that this is a horizontal 5-axis machining center from Japan. The advantage of this equipment is that the hydraulic manifold block can be processed with just one clamping of the blank parts. Most hydraulic manifold manufacturers process one surface before processing another, which not only has low efficiency but also poses risks of inaccurate positioning. AAK technicians first place the rough piece of the hydraulic manifold block on the fixture, position it while calibrating it with a balance ruler, then tighten the fixture and calibrate it again with a balance ruler until the positioning is correct, and then start the equipment. The dual box structure of this equipment ensures stable machining accuracy. Especially when the rectangular guide rail is combined with the movable mechanical structure of the column, the cutting becomes smoother and the accuracy of the valve hole is also stable. AAK hydraulic manifold blocks, processed with a 5-axis machining center, welcome to try it out!
