Evander comes from a Greek hydraulic equipment company and has been in the company for 5 years. At the beginning of the year, the hydraulic stretching machine they developed needed to purchase hydraulic directional control valves with large length diameter ratio. He chose to work with a supplier for 3 years to try, and the manufacturer reported that the length diameter ratio of the valve hole of the hydraulic directional control valve is 20:1, and the valve hole Ra is not more than 0.3. He is not confident, but he can try. 2 months later, the test run was not smooth. Indeed, the hydraulic direction control valve was slow to respond, and the manufacturer surrendered. Evander contacted more than another 10 hydraulic valve manufacturers for this hydraulic directional control valve, but all of them are not 100% confident of doing this valve with the length diameter ratio of 20:1. 10 weeks have passed, but the manufacturer has not been determined yet. Evander is very worried. Evander saw an article of AAK on B2B about "Hydraulic relief valve with length diameter ratio of 11:1" and left a message to AAK: Is AAK confident to do a hydraulic directional control valve with the length diameter ratio of 20:1 and Ra is not more than 0.3? My reply: It's right to ask AAK about the length diameter ratio. We have produced 25:1 hydraulic check valves in mass production. It is suggested that he send his drawings of hydraulic directional control valve and AAK directly make samples. If the length diameter ratio is not in accordance with the standard, the development cost will be returned. Evander is happy and nervous. He is happy that the manufacturer has been determined. He is afraid of wasting time. Evander waited for 4 weeks in fear, until his engineer told him that the processing size and accuracy of the AAK hydraulic directional control valve were up to standard, and the test machine was also successful, and Evander was completely relieved. I told him that the hydraulic directional control valve with deep hole is difficult to process. The greater the length diameter ratio, the more difficult it is. Even if it is processed, the precision is a hidden danger. This is also the reason why many hydraulic valve manufacturers surrender. AAK adheres to the size accuracy, geometric accuracy and surface roughness of the valve hole, and optimizes the processing technology. We do in the following way, it is difficult for the general hydraulic valve manufacturers to imitate. 1. According to the blank condition, steel properties, length diameter ratio, determine the drill and fixture, which requires experience and skill. In the 6 procedures of "drilling - expanding - boring - reaming - rigid boring reaming - diamond reaming", the cutting amount and working temperature are strictly controlled. 2. The rigid boring reamer is equipped with a guide at the front and back, ensuring straightness, especially the internal cooling chip removal, ensuring the surface finish of the valve hole. 3. For the processing of this hydraulic directional control valve, the tool change frequency is 3 times of the conventional one, the geometric accuracy of the sample is 0.002mm, and the surface Ra0.2. AAK hydraulic directional control valve, has unique trick on valve hole processing, high precision, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-directional-control-valves- aak35 , 1

When negotiating prices with customers, AAK hydraulic valves often encounter a problem that new customers often think the price is expensive. Due to the different quality of hydraulic valves, the price difference is some big. Sometimes, when we encounter customers who only focus on the price, we have no choice. On the weekend, I went to the decoration market and wanted to buy some paint and paint the background wall. Passing by the Dulux Paint Shop, I saw a conversation between a young sales girl and a middle-aged man. I stopped, listened carefully, and learned a good lesson. Dulux paint is definitely expensive. It's a big brand, and many customers think it's expensive, but this young girl says it's cheap. The young girl is saying, "Your paint usage is 400 square meters. If using other small brands paint, it would be around 24,000 yuan, but if using our Dulux paint, it would cost 48,000 yuan, which is twice as expensive. I also think it's expensive, but in the end, I think it's cheap." This is the opening phrase of this young sales girl, which is very organized. The young girl continued, 'Your renovation will last for 15 years, which means you only need to spend 8 yuan per day to buy over 400 square meters of Dulux brand paint.'. The young girl is very smart and converted the high price of 48,000 yuan into 8 yuan. A principle of 'calculating small accounts, calculating breakdown accounts'. The middle-aged man's expression suddenly became relaxed and he also nodded. The young girl continued, 'Dulux's paint is free of methanol and harmful substances. Spending an extra 4 yuan per day only is to earn health, especially beneficial for your child’. The benefits of Dulux paint were presented to the user, and the middle-aged man nodded again. The young girl continued, 'You have a luxury home worth millions of yuan, and choosing a big brand paint is certainly the best match. You have already spent 10 million, still care about this 48,000?’ In less than half an hour, the middle-aged man paid the deposit, signed the contract, and left. I admire the young girl's move, with the knife in place. On the way back, I pondered the young girl's bargaining skills, which could also be extended to the AAK hydraulic valves. When customers feel that AAK price is expensive, we need to calculate breakdown accounts, such as the service life of AAK hydraulic valves, and discuss the service life with them. For example, if the service life of hydraulic valves in the same industry is 1 year, and the service of AAK hydraulic valves can reach 2 years, after the price is evenly divided to every day, the cost-effectiveness of AAK hydraulic valve prices is shown out. Although AAK hydraulic valves are 20% more expensive, their service life is twice that of other similar valves produced by other hydraulic valve manufacturers in China.

Bauer is from Brazil, and has purchased hydraulic cartridge valves from AAK for 3 years. A batch of 70 pcs hydraulic flow control cartridge valves had to ship before CNY, due to the epidemic situation, AAK workshop stopped production for 11 days, resulting in the batch of hydraulic flow control cartridge valves not being shipped on time. Bauer understood the situation, because this guy also knew that I was doing my best. It was finally shipped last week, and Bauer was relieved, and can hand over the goods to the customer. In the middle of December last year, Bauer wanted to customize 70 hydraulic flow control cartridge valves. The adjusting knob must be durable and easy to operate. I made fun of him: Did you encounter problem so that you think of AAK cartridge valve? He told me that these hydraulic flow control cartridge valves were purchased from a local cartridge valve manufacturer in Brazil. During the daily equipment maintenance, their hydraulic cylinder customer found that the knob of the hydraulic flow control cartridge valve torque was large, difficult to turn, and inconvenient. The manufacturer of the original hydraulic flow control cartridge valve reported that only the knob of this structure could be used, otherwise it would not be durable. Bauer didn't believe it, so he came to me. AAK engineer disassembled the structure of the original hydraulic flow control cartridge valve, combined with the working conditions of the hydraulic cylinder, and found that the original hydraulic flow control cartridge valve knob can be replaced by a new structure. Bauer asked me to arrange production immediately, and needed to ship before CNY, which means it would have only 30+ days to reprogram and produce 70 hydraulic flow control cartridge valves. I told him that I would go all out, if without accident, it could be shipped before CNY. AAK hydraulic flow control cartridge valve knob system includes positioning rod, adjusting handle, positioning rod adjusting screw and adjusting screw seat. The upper end of the adjusting screw seat is provided with a screw hole that is suitable for the thread of the adjusting screw of the positioning rod, and the upper end of the adjusting screw of the positioning rod is fixedly connected with the handle. This structure is completely different from the concept of the Brazilian cartridge valve manufacturer. It is not only easy to operate, but also more durable. 1.Between the lower end of the positioning rod adjusting screw and the upper end of the valve opening positioning rod, there is an intermediate transition adjustment shaft, and the lower end of the intermediate transition adjustment shaft and the upper end are also provided with a step shaft. 2. The lower end of the adjusting screw seat is equipped with an adaptive adjusting shaft positioning hole. The valve opening positioning rod is a ladder rod with the upper end diameter greater than the lower end diameter. The upper end of the ladder rod is equipped with an adaptive adjusting shaft connecting hole. 3. The valve cover is provided with an upper round hole and a lower round hole which are respectively suitable for the reciprocating dynamic seal at the upper and lower ends of the positioning rod. The upper end of the positioning rod, the lower end of the adjusting screw seat, the side of the intermediate transition adjusting shaft, and the corresponding hole surface on the valve cover form a pressure relief oil chamber of the adjusting screw. The valve cover is equipped with a guide oil passage. The positioning rod is located below the connecting hole of the adjusting shaft, and is equipped with a liquid return oil passage. AAK hydraulic flow control cartridge valve, the knob adjustment has unique skills, you can also try it! https://www.aakindustry.com/info-detail , /flow-control-cartridge-valves-aak503

Lateef, from Sweden, has been engaged in the procurement of hydraulic valves for 3 years and has been quite successful. Last year, however, he stumbled due to a hydraulic pressure control valve used in a hydraulic climbing vehicle. At the beginning of last year, their hydraulic climbing car was complained by customers that it was unable to rise. During after sales service, it was judged that the hydraulic pressure control valve was abnormal, and must be replaced. The original manufacturer refused to be responsible, because it has passed the 1 year warranty period. Lateef was embarrassed after checking, because after the hydraulic pressure control valves were shipped from the original manufacturer to their warehouse, their hydraulic climbing cars were delivered to the customer 4 month later, so the equipment was still within warranty. The boss was unhappy, Lateef was helpless. He tried to raise the warranty period of the hydraulic pressure control valves to 24 months to source new hydraulic valve manufacturers, but no reply from more than 10 manufacturers that he contacted. Lateef went from helplessness to anxiety. Lateef found AAK on B2B and left a message on AAK website: How long is the warranty period of hydraulic pressure control valve? I needed him to provide us drawings for discussion. According to his hydraulic pressure control valve drawing and working condition requirements, it is actually the standard part of SUN hydraulics. AAK has this procedure. I asked why he requires a 24 months of service life for the hydraulic pressure control valve, instead of requiring the number of durability times. Then he told me the above purchasing experience and sent me several hydraulic pressure valves from the original manufacturer. Our engineer found during disassembly that some valve spool cylindrical surface and conical surface, as well as the valve cage inner hole and conical surface are not concentric, which is a problem in accuracy and affects the function. The cone surface of some valve spool is worn, which affects the sealing, and the performance is not up to standard. Lateef was surprised to hear this, because no manufacturer gave him such analysis. I told him that AAK has a similar hydraulic pressure control valve. You can install it on the equipment for testing. If you can install it, you should not worry about customer complaints. He was surprised and happy. More than 10 hydraulic valve manufacturers had no reply, but AAK could send samples directly. 2 weeks later, Lateef informed that the hydraulic climbing vehicle equipped with AAK hydraulic pressure control valve could work normally. He also asked about the warranty period of the hydraulic pressure control valve. I told him that AAK was benchmarking SUN, and its performance was 2 million times. As long as the equipment was used no more than 2500 times a day, there was no problem in 24 months. AAK hydraulic pressure control valve, benchmarking SUN, adhere to 3 aspects, Lateef is completely relieved. 1. The material is strictly selected. The valve spool is made of 20CrNi2MoV from Germany. The wear resistance of the valve spool is more than 3 times that of the material used by other hydraulic valve manufacturers. The other manufacturers may have the performance of 500,000 to 1 million times, while AAK has the performance of 2 million times. 2. The precision is strictly controlled. The valve hole of this model is finely processed by American precision honing machine, and the precision of valve hole of other hydraulic valve manufacturers is 0.8 μm - 1.0μm, while AAK can be 0.6μm - 0.8μm. The precision is increased by 25% - 30%. 3. Strict inspection, equipped with a German Test high-precision measuring instrument for small micropore diameter, fully inspect each valve hole, while most hydraulic valve manufacturers only conduct sampling inspection randomly. AAK hydraulic pressure control valve, not only strict, you can also try a small order! https://www.aakindustry.com/info , -detail/hydraulic-pressure-control-valves- aak3 , 50

Gonzalo comes from Spain and has been purchasing hydraulic valves from Chinese manufacturers for 3 years. At the beginning of last year, they developed hydraulic gantry shears and needed to purchase hydraulic cartridge relief valves. The engineer directly purchased German HAWE standard parts, and the prototype was commissioned and purchased. The boss asked to reduce the purchase cost to match the market price of similar equipment. After comparing prices, Gonzalo selected a hydraulic relief valve manufacturer in Ningbo. 6 months after the equipment was sold, the customer complained that the hydraulic gantry shear was weak. During after sales service, the valve spool of the hydraulic relief valve was found to be worn and could only be replaced. The original manufacturer fed back that the service life of the hydraulic relief valve under 450bar high-pressure working condition was normal for 6 months. The boss was not happy. Gonzalo was under pressure. His engineer said that the service life of the HAWE hydraulic relief valve was no less than 1 year. Gonzalo contacted more than 10 hydraulic relief valve manufacturers, they could not bear high pressure or can not guarantee a service life of more than 1 year. Gonzalo found AAK in Google's China hydraulic valve manufacturers list. When he learned that AAK had engineer from HAWE, he saw hope. According to his hydraulic relief valve drawing, it is not too difficult, just needs to be high pressure resistance and performance. Because we have no program for this HAWE hydraulic relief valve, we need time to develop it. After 45 days, we delivered 80 samples of hydraulic relief valves, and told Gonzalo that if you replace those complained hydraulic relief valves with AAK's, you will have no pressure. A few days ago, Gonzalo sent an email. It has been proved that AAK's hydraulic relief valves can last for 1 year under high pressure of 450bar, more than twice as long as that of the original hydraulic valve manufacturer. In the subdivision field of high pressure resistance, AAK hydraulic valve manufacturing quality benchmark is HAWE, because HAWE is the No 1 of this field. We mainly focus on 3 points. It may be difficult to find the second one, from more than 200 hydraulic valve manufacturers in Ningbo. 1. Strict selection of materials: YG8 cemented carbide is selected for the valve spool of this hydraulic relief valve, and the content of tungsten carbide (WC) and binder cobalt (CO) is the best of the same kind of steel. The wear resistance and impact resistance have been improved by more than 2 times. Under the pressure of 450bar, there is no wear within 1 year. 2. The control equipment: the valve spool of this hydraulic relief valve is finely processed with a Swiss high-precision honing machine. The precision of the valve spool is fixed at 1-2μm, surface roughness Ra0.2-0.3, which is difficult for most manufacturers to achieve. 3. 100% testing: AAK independently developed durability testing equipment, implemented NFPA/T2.6.1 standard, and each hydraulic relief valve was inspected. Most manufacturers conduct selected checks and do not have good testing equipment. AAK hydraulic relief valve, resistant to 450bar high pressure, durable for more than 1 year, benchmarking HAWE, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak349

Peter is from Australia. One of his old customers wanted to purchase a special hydraulic flow control valve. Peter realized that the valve hole of this hydraulic flow control valve has high accuracy and is difficult to process. If the surface roughness and cylindricity error cannot be well controlled, it is easy to cause the valve spool to be stuck. As expected, he contacted more than 20 hydraulic flow control valve manufacturers in 3 days, but none of them was confident. The customer has urged the quotation twice, and now even the manufacturer can't be determined. Peter was very worried. Peter wanted to find more hydraulic flow control valve manufacturers in different countries online this time. He accidentally found AAK hydraulic valves and stayed on AAK website for about 20 minutes. With the attitude of trying, he sent me an email. After communication, we learned that his customer was pushing urgently and he needed AAK to quote asap. I didn't make an offer the next day. Maybe Peter thought AAK had surrendered. Later, I told him that most hydraulic valve manufacturers still use traditional processing methods to process the valve hole of this hydraulic flow control valve. According to the requirements of the drawing parameters, they also know that the surface roughness is a threshold. For example, the abrasive particles are easy to be embedded in the workpiece surface, and the cutting is not easy to be separated from the grinding oil, resulting in poor cleanliness of the grinding oil. All these affect the surface roughness. AAK realized this processing pain point as early as 4 years ago and adopted rolling technology to replace the traditional cutting method. I suggested that he communicate with the customer and let AAK directly test the sample. If the sample is successful, it will be quoted. If the sample fails, AAK will bear the development cost. On the 3rd day, Peter accepted my suggestion. After 35 days, 12 samples of hydraulic flow valves were sent out. About 2 weeks later, Peter said that his client confirmed AAK's hydraulic flow control valve. At this time, Peter realized the advantages of AAK and thanked me very much, which helped him face his old customer. Rolling technology and cutting processing are completely 2 different processing methods. AAK tried, solidified and mass produced it 4 years ago. Roll the metal surface with rollers, flatten the convex part of the surface, and bulge the concave part, and then process it into a smooth mirror like surface. The most important thing here is the rolling details. The surface roughness of the valve hole processed by the old experienced technicians will be increased to nearly 1% compared with the surface roughness after grinding, so that RA is 0.10 ~ 0.15, and the cylindricity error is controlled within 0.003. After work surface hardening, the wear resistance is improved, and the fatigue strength can be increased by 30%. There are many advantages, but there are not many manufacturers of hydraulic flow valves using this process, and even fewer can control the details. 3 days later, Peter sent the PO for the hydraulic flow control valve. He told me that the stone hanging in his heart finally fell, and the meal was more delicious. I told him that you only need time to receive the goods. Go to the bar when you need to, and leave the rest to AAK. AAK hydraulic flow control valve, has unique skills with special requirements. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak348

Quentin is from Italy. He is a new purchaser of a company which has cooperated with AAK for 4 years. He is very aggressive, but the first purchase of hydraulic relief valves overturned. At the beginning of this year, a batch of excavators of their company needed hydraulic relief valves, which were standard parts of HydraForce. Quentin asked more than 10 hydraulic cartridge valve manufacturers, and chose one manufacturer that is 60% cheaper than HydraForce to place an order. Six months later, trouble began. A customer complained that the oil pipe of the excavator burst. The engineer realized that it was not just the problem of replacing the oil pipe. It was found through inspection that the hydraulic relief valve was sluggish during operation, resulting in the instantaneous formation of peak pressure in the system, which caused the oil pipe to burst. The inner wall of the valve hole of these hydraulic relief valves was worn. However, the manufacturer of the original hydraulic relief valves said that it was caused by the unclean hydraulic oil, which had nothing to do with them. Quentin was afraid to take responsibility and dared not report to his boss. Quentin was very nervous. He contacted several manufacturers of hydraulic relief valves, but no gain. Carter, another old purchaser, saw that he was at a loss and suggested that he has a try with AAK hydraulic valves. Quentin emailed me and asked if the program of this HydraForce valve was available. Only then did I know that his first purchase of hydraulic relief valve was not smooth. I sent him the pictures and technical parameters of the hydraulic relief valve. The next day, he asked me to deliver 50 hydraulic relief valves first to solve customer complaints urgently. Two weeks later, Quentin informed that the replacement work was completed and the excavator could work. Quentin said that although the price of AAK is 30% higher than that of the original manufacturer with hidden quality problems, it is still 30% cheaper than that of HydraForce, and the surface treatment of AAK hydraulic relief valve is more textured than that of HydraForce. I told him that AAK hydraulic relief valve not only has the appearance value, but also has the performance of no less than 2 million times. The reason why AAK hydraulic relief valve can be compared with HydraForce is that AAK insists on selecting the most suitable steel, even if the processing cost is 2-3 times more expensive, it should also choose the best. AAK can't do anything that is not good enough, let alone give it to users. We always adhere to the following 3 points: 1. The material selection is "cleanliness". The A + material is used to replace the A material of the standard part. For example, 3Cr3Mo3W2V is used to produce the valve body of this hydraulic relief valve. Compared with similar steels, its hardness, strength, wear resistance and toughness have all improved to a new level. It ensures the impact resistance of the hydraulic relief valve during the working process of the system, and stands guard for the performance of 2 million times. 2. The selection of equipment is "guaranteed". The valve hole of the hydraulic relief valve is precision machined with Swiss high-precision honing machine, and the accuracy of the valve hole can reach 1.0μm, while most manufacturers of hydraulic relief valves are in the range of 2μm. 3. For surface treatment, AAK insists on using galvanized nickel alloy to replace the galvanized treatment of HydraForce. It is not only beautiful, but also textural. Quentin told me in private that in his conversation with me, he was more determined to do a good job in purchasing. This time, he solved the customer's complaints in time, and his boss was happy to see him. AAK hydraulic relief valve surpasses its domestic counterparts and benchmarkes with HydraForce. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak347

Many Chinese hydraulic manifold manufacturers are quite tired because they think too much and do too little. There are also Chinese hydraulic manifold manufacturers who cannot digest customer inquiries and still compete. A person's fatigue is also due to their desires and abilities, which cannot be directly proportional.   Little birds build nests in dense forests, all they need is a branch; The groundhog only needs to fill its stomach when it comes to the big river to drink water. The little dog is following you, what he needs is just a touch from you. Similarly, what people really need is actually very few, but people like to be greedy. So why live so tired? Because your desires are endless. The fatigue of Chinese hydraulic manifold manufacturers is also due to the desire for orders.   An inquiry is simple for Chinese hydraulic manifold manufacturers, but when the order arrives, can it be easily processed or digested? This is not only related to manufacturing quality, but also to daily production capacity and your goodwill.   Chinese hydraulic manifold manufacturer AAK focuses on manufacturing quality, including material selection, process settings, processing, equipment, and production line stability. Each process has standards and quality inspection. The manufacturing quality of AAK hydraulic manifolds lies in these 5 points. The manufacturing quality of hydraulic manifold is slower, more clumsy, and more solid than that of intelligent people. There is no shortcut on this road. There is no safe haven either. Without manufacturing quality as 1 takes the lead in the front, and any additional 0 added later will eventually return to zero. Just like in life, at the top of the waves, can you stand still? At the bottom of the waves, can you hold still?   A person's evil is usually obsessed with using bottomless methods to reach their goals. The evil of a Chinese hydraulic manifold manufacturer is also obsessed with taking orders without a bottom line. Whether it is a Chinese hydraulic manifold manufacturer or an individual, we must be kind. Good has no specific direction, whether for customers, suppliers, employees, or friends. Those who are capable rely on themselves for success, while those who are good rely on heaven for success. Heaven does not refer to God or immortals, but to the uncertainty of what one relies on.   Chinese hydraulic manifold manufacturer AAK has 1 inquiry every day, and 1-2 orders arrive every week, neither seeking nor greedy.   AAK HYDRAULIC VALVES (688) 2023-10-08 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers-aak688

A China solenoid valve manufacturer needs to possess 3 elements, to gain customer trust: reliability, trustworthiness, and approachability.   Firstly, the sales representative (the person in contact with the customer) should be reliable. Reliable, one must be reliable, always have an explanation, everything has a place, and everything has an response. Only by meeting these 3 points, the sales representatives are reliable.    Secondly, trustworthiness. This is aimed at China solenoid valve manufacturers, with a focus on "credible". It does not come from the China solenoid valve manufacturers themselves, but from the social network in which they operate. For example, a young surgeon who claims to have worked at Mayo Clinic for 7 years has gained credibility in the medical industry solely based on this identity. For example, AAK hydraulic valve, AAK is the supplier of HydraForce for 9 consecutive years and Sun hydraulic for 5 consecutive years Good at various styles of Hydraulic Screw-in Cartridge Valves, Blocks, and Manifolds. My friend's company recruits drivers, but the first requirement is not the driver's skills, but these 3 points: first, the person has to get married; Secondly, he has to live with his family; Thirdly, he must have children, and the children must be at school. You see, these 3 conditions are all external social network conditions of a person. With these 3 conditions, he is likely to be a hardworking and caring person. So you see, the so-called ability growth is a part of one's own efforts, and the trust that can be gained in the appropriate social network is also a more important part. The same applies to enterprises, the manufacturing quality of Chinese solenoid valve manufacturers is a core part, but the trust that can be obtained in a suitable social network is also a more important part. Finally, approachability, this is a result. For example, the trust state defined by AAK and customers after several rounds of interaction. A person's abilities are reflected in 2 aspects: one is the reliability brought by improving their business abilities, and the other is the credibility determined by their position in the social network. The capabilities of a Chinese solenoid valve manufacturer are reflected in 2 aspects: one is to improve the reliability of the solenoid valve by improving its manufacturing quality, and the other is the credibility determined by its position in the social network, which is also the core of trust. AAK, a China solenoid valve manufacturer, uses its own reliability, credibility, and has gained the approachability to customers.

Elon Musk's acquisition of Twitter has already been implemented, which is also old news. Musk fired all employees of a total of 12 floors. Now Twitter has less than 50 core staff maintaining the operation of Twitter, which had 7,500 employees in 2021. Musk said that it is unnecessary to hire so many lazy people who do not work. Why does Musk do this? Maybe only he knows it best. The impact on me is that the values distinguish different people. AAK hydraulic manifold is to screen and eliminate people with efficiency.   Musk is a person who pursues the ultimate efficiency. The first thing to do in acquiring Twitter is to screen out the people who can work at the speed and efficiency he requires. A person who is highly demanding of his own efficiency can hardly bear the inefficiency of others. Frankly speaking, I also have this tendency. 996 is a holiday for me, 007 (from 0 to 0, 7 days a week without rest) is my normal state, especially in the early days of entrepreneurship, 612 mode every day (going out at 6 o'clock in the morning, going home at 12 o'clock at night). 365 days a year, 362 working days, only 3 day of holiday during the Spring Festival. For AAK hydraulic manifold, every internal meeting, I often say: I can accept that you are not so smart and have a low starting point, but I can hardly accept that you are not diligent enough, work inefficiently, meet problems mechanically, or avoid problems and choose to lie flat. When you meet problems, solve them, do not escape, do not throw away the pot, and constantly improve your knowledge system of hydraulic valves, as well as service awareness, you can make rapid progress.   If two people with different values work together, when the values of efficiency and comfort collide, there will be a great sense of tear, and both parties will suffer. Like fire, meeting ice. Only when "ice" evolves into "flammable ice", which looks like ice and burns when it meets fire, can the two sides merge, and then react, and the collision produces amazing energy. In AAK hydraulic manifold, in a word, whoever suffers will change.   In the 13 years of development, AAK hydraulic manifold has also taken a detour and paid a price, especially at the level of management efficiency. At the beginning of the establishment of AAK hydraulic manifolds, everyone started in one direction; Work hard. But then they began to expand themselves. Some managers showed that they were busy and important by increasing the number of their small teams and splitting the workload. They felt that AAK hydraulic manifold could not do without him, which dragged the development of AAK hydraulic manifolds.   From the perspective of humanity, I share the story of my high school classmate who worked in the middle level of SAP's Shanghai office in Germany. Some time ago, since the epidemic, SAP business has been cumbersome, and the number and difficulty of things to be handled have become increasingly large. He used to make few mistakes, but recently he has become more and more powerless. Being criticized by the boss and questioning how old employees can make such mistakes? Whenever he left his boss's office, he heard his boss's heavy sigh behind him. What will he do? His son's tuition in the United States is high, and Shanghai's housing loan is also heavy. He drove the car, feeling melancholy, and came to the garage. The lights in the garage were bright and dark; The smoke in his hand was extinguished and lit again, and it was quiet for a long time.   He knew that he had only 3 choices: 1. Resign and transfer the position to a better person. 2. Hire a better person to help yourself. 3. Appoint two people who are slightly lower than you as assistants to do a good job together. Most people will choose the third one. First, once you resign, you will fall into an economic crisis. Second, that person is likely to become a future opponent. Only the third is to find someone to share your work. Your son's tuition is available. Two mediocre subordinates are not threatening themselves. If there is too much of work to complete, they will find subordinates, and subordinates will find subordinates. The staff keeps expanding, everyone is busy, but the efficiency is extremely low.   AAK hydraulic manifolds, focus on efficiency, refuse to drag. The position of 1 person can give you 2 salaries, but you need to generate the efficiency of 3 people and the growth of 5 people. Yes, AAK hydraulic manifold is the one that requires, screens and eliminates people in the 1,2,3,5 mode. https://www.aakindustry.com/info-deta , il/hydraulic-manifold-aak430

These days, the 19th Asian Games have been going viral in Hangzhou. Due to the National Day holiday, all hydraulic manifold manufacturers in China are on vacation. I also visited the Asian Games in Hangzhou and visited a company started by a college classmate's child. My classmate also works for a hydraulic manifold manufacturer, but his son doesn't want to inherit his father's business to work at a hydraulic manifold manufacturer. Instead, he started an AI intelligent type company.   This young man has only graduated for 3 years, and the company's annual profit can exceed 12 million yuan, which can be considered a rapidly growing new company. It would be great if a new hydraulic manifold manufacturer in Ningbo can earn back their investment in 3 years. Even a hydraulic manifold manufacturer with a lifespan of 10 years can make an annual profit of over 12 million RMB, which cannot be found in Ningbo. I have summarized several key points for this young man's success:   1. To attend a good university, he graduated from Zhejiang University, similar to Stanford University in the United States, is quite outstanding in the field of computer science. 2. Choose a good major, he specializes in AI visualization. 3. There should be a good mentor, his entrepreneurship is facilitated by his mentor. 4. Have your own characteristics, be unique, and persist in being stubborn. 5. The clients are all among the top 50 in China and are all listed companies.   From this new type of AI startup, I thought of my hydraulic manifold manufacturer AAK. We may not have been successful yet, but along the way, we have also achieved several key points:   1. Hydraulic manifold manufacturers need to choose a good direction, most of which are concentrated in the domestic market, while AAK only focuses on overseas markets. 2. Hydraulic manifold manufacturers should have a correct concept, and AAK adheres to two major stability principles: quality stability and technical stability. 3. The hydraulic manifold manufacturer needs a customer who is similar to a VIP, and AAK is grateful for Honeywell's support. Their understanding and requirements have promoted AAK's growth. 4. Hydraulic manifold manufacturers should have their own characteristics, and AAK targets SUN's manufacturing quality, but the price is less than 70% of theirs. 5. Customers of hydraulic manifold manufacturers should be meticulous. If your customers only compare price, not quality, then your quality cannot be stable. AAK is fortunate to have Fortune 500 customers like Honeywell and industry- leading customer groups like SUN Hydraulics.   Hydraulic manifold manufacturer AAK, is slow hearted and diligent, implementing step by step, one key point, a good meal is never too late.   AAK HYDRAULIC VALVES (687) 2023-10-07 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers-aak687

Colon comes from Turkey. They are distributors of HydraForce, Rexroth, Eaton, BUCHER, HAWE, and SUN hydraulics brands. They also often customize cartridge valves from overseas manufacturers. They have cooperated with AAK for 4 years. The AAK cartridge valve standard parts that benchmark SUN are loved by Colon. At the beginning of last year, Colon wanted to customize a hydraulic directional cartridge valve and expedite it.   After communication, it was learned that the hydraulic directional cartridge valve produced by the original manufacturer leaked due to the wear of the sealing ring after 6 months of use by the customer. The original manufacturer changed to use fluororubber sealing ring, but 6 months later, the old problem occurred again. The customer requested to use better sealing for the hydraulic directional cartridge valve. The original manufacturer prevaricated that the opening and closing work of the system is too frequent. No matter what material of sealing ring is used, the service life of the hydraulic direction cartridge valve can only be guaranteed for 6 months. The boss requested that the manufacturer of hydraulic directional cartridge valve be replaced, and the service life should not be less than 12 months, and the delivery time should be as fast as possible. Colon was in a hurry and came to me for help   According to his description, our engineer believed that the original manufacturer's judgment is correct. No matter what material seal ring is used, the hydraulic directional cartridge valve will have a service life no more than 6 months. Colon was a little confused: How can we explain this to the customer? 2 days later, I told Colon that replacing the sealing ring is not the only option to improve the sealing effect, but also to change the sealing method. Colon was very happy to know that AAK had an optimization plan. After 48 days, AAK sent 24 samples of hydraulic directional cartridge valves.   Yesterday, Colon emailed us and placed an order for 160 hydraulic directional cartridge valves. He told me that his boss and customer were very satisfied with AAK's customized hydraulic directional cartridge valve, which had no abnormality and leakage for 1 year. AAK hydraulic directional cartridge valve used a special PU polyurethane rubber sealing ring from Japan. At the same time, we made improvement on the structure of the sealing ring, to ensure 3 advantages: double sealing, zero leakage, and long service life. It replaced the valve produced by the original cartridge valve manufacturer, and also impressed the customer and boss.   1. The valve sleeve is connected with the valve body of the hydraulic directional cartridge valve by screwing. The first sealing device is set at the connection, equipped with L-shaped rubber gasket, and connected with the valve body by clamping. Most cartridge valve manufacturers dare not use these 2 connection methods.   2. The poppet spool of the hydraulic directional cartridge valve is inserted and connected with the valve sleeve by inlay. The right side of the poppet spool has a spring seat. The spring is connected with the poppet spool and the spring seat through penetration.   3. There is a second sealing device at the bottom of the thread at one end of the valve body of the hydraulic directional cartridge valve, which is connected with the valve body by clamping. There is a second sealing ring at the outside of the connecting clamp, and the other end of the valve body is also connected with the cover plate by screwing.   AAK hydraulic directional cartridge valve, double seal, zero leakage, long service life, no trouble in purchasing, you can also customize it! https://www.aakindustry.com/info-detail , /directional-cartridge-valves-aak502
