A while ago, Basel from Spain left a message on the website of hydraulic cartridge valve manufacturer AAK: Can you GUARANTEE that the cylindricity of the cage of the hydraulic cartridge valve is controlled within 0.3µm, and the accuracy of within 2μm? With the word“GUARANTEE” capitalized, I can feel Basel's emotions, he should have received promises from other hydraulic cartridge valve manufacturers, but he has been hurt. After communication, it was learned that Basel had tested the samples from a hydraulic cartridge valve manufacturer in Ningbo China. The 6 testing samples passed the requirements of 0.3µm cylindricity and 2μm accuracy for the valve cage. However, the 480 pcs of shipment had accuracy issue. That is to say, the machining accuracy of the original hydraulic cartridge valve manufacturer is unstable. For hydraulic cartridge valve cages with high precision requirements, subsequent honing is crucial. The consistent thinking of hydraulic cartridge valve manufacturer AAK is a 3-step process: what has been done, why is this done, and what else needs to be done? For the honing of the hydraulic cartridge valve cage, AAK has an automatic control honing machine SUNNEN from the United States. The equipment is equipped with a SAC size automatic control system. When the honing accuracy meets the system requirements, it can automatically stop, especially with the setting of oil and stone slow advance, providing assurance for the surface roughness and cylindricity of the hydraulic cartridge valve cage. Our technicians first match the corresponding fixtures based on the external contour of the hydraulic cartridge valve cage. Then fit the hydraulic cartridge valve into the equipment, and the equipment can automatically perform honing. This is our first step, making fixtures and then grinding. Why do we have to do this? Most hydraulic cartridge valve manufacturers prefer to use universal fixtures that come with their equipment, but AAK focuses on customizing fixtures based on the hydraulic cartridge valve cage, in order to achieve high-precision stability. What else does AAK do? After honing the valve cage of the hydraulic cartridge valve, compare each valve cage with a plug gauge. If it is not qualified, it will be discarded. Most hydraulic cartridge valve manufacturers in Ningbo China may not have this detail. AAK hydraulic cartridge valve, the consistent thinking of always takes 3 steps, you can also give it a try!

For hydraulic cartridge relief valves with precise small holes, most of manufacturers encountered penetration when processing the Φ4.5H7、Φ4.7H7 holes. AAK used 3 advantages, which not only prevented penetration for 100%, but also reached R0.2mm at the bottom of the small holes. After receiving the samples of AAK hydraulic cartridge relief valves, Arvin sent a PO for hydraulic cartridge relief valves of 20,000 dollars. Precise small holes of hydraulic cartridge relief valves is a difficult problem in machining. The vast majority of hydraulic cartridge valve manufacturers have difficulty in controlling the processing tools, cutting parameters, cutting stress and processing technology, resulting in easy deformation of components or substandard accuracy. What's more, it is unstable. For example, the precision of the small holes of this batch of hydraulic cartridge relief valves reached the standard, but the next batch has hidden dangers. The most taboo about the quality of industrial products is instability. Arvin is from a hydraulic company in the United States. Recently, he was overwhelmed by a hydraulic cartridge relief valve with high requirements for machining accuracy and form and position accuracy. He selected a hydraulic cartridge relief valve manufacturer cooperated for 4 years to make samples. The samples were made by 3 times, but all failed, and the accuracy was not improved again and again, but was good and bad. Arvin had to give up this old supplier and contacted 20 hydraulic cartridge relief valve manufacturers. They either did not reply or gave up directly. Arvin found AAK hydraulic valves in B2B and left a message: Can you customize the hydraulic cartridge relief valve with precise small holes? After communication, I learned that he was troubled by the difficult machining of precision small holes of hydraulic cartridge relief valve. According to the parameter requirements of hydraulic cartridge relief valve, the hardness, wear resistance, corrosion resistance and surface treatment, all requirements are very high. After half a day of discussion, AAK technical team came up with the process plan. I told Arvin that AAK was 90% sure to solve the problem, and the standard deviation (Sigma) accuracy of size could be stable in different batches. 2 days later, Arvin asked me to make samples. After 30 days, AAK sent 6 hydraulic cartridge relief valves. 12 days later, Arvin returned a PO for the hydraulic cartridge relief valve worth 20,000 US dollars. In order to improve and stabilize the holes accuracy of hydraulic cartridge relief valve, AAK optimized 3 points: 1. Processing equipment: It is easy to process the hole into a taper hole by conventional grinding. The Swiss precision lathe is the first choice for processing the precision small holes of this hydraulic cartridge relief valve. 2. Tool and tool parameters: Six tooth 1201/4.6H7 and 1201/4.8H7 reamers are used as finishing tools, and the tool tip is grinded to R0.2mm to avoid penetration. 3. Fixture improvement: In order to ensure the state of precision holes during semi finishing, AAK uses self-made floating spring chuck to hold the reamer, avoiding horizontal axial or vertical space errors, which is conducive to precision and better standard deviation. AAK hydraulic cartridge relief valve precision small holes, only 3 steps to ensure quality, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-relief-valves- aak402

This morning, Joselito sent an email asking about the production time of 1,000 hydraulic manifold blocks, which surprised me a little, because in the past two years, Joselito has basically placed orders for just hydraulic valves only, but very few for the hydraulic manifold blocks. Joselito is a purchaser of BEZARES company in Spain. We met 2 years ago. After communication, it was learned that he encountered problem on the hydraulic manifold blocks purchased this time. A batch of hydraulic winch equipment of their company was complained by some users that the winch was often weak. Their after sales found that the hydraulic manifold block was leaking. Because of the purchase cost limitation, he disassembled the hydraulic manifold blocks and purchased them separately from 3 hydraulic valve manufacturers. Now the leakage problem of the hydraulic manifold blocks has come, all 3 manufactures prevaricate and are not responsible for the oil leakage of the hydraulic manifold blocks, they thought that the problem was caused by the unreasonable design or the wrong installation method of the hydraulic manifold blocks. The engineer checked the hydraulic manifold blocks one by one and found different problems, some sealing ring was broken, some gasket at the interface was worn, and some has iron filings in the valve hole. In the past year, a lot of money, labor and maintenance costs were spent on the after-sales for the hydraulic manifold blocks. Now the customers are not satisfied with their after-sales performance, and the boss is not happy to spend the after-sales money indiscriminately. Joselito has a big headache. AAK suggests that Joselito should purchase the whole hydraulic manifold blocks in one factory as much as possible, because each hydraulic valve manufacturer has different quality positioning. AAK has now received more and more inquiries for hydraulic manifold blocks, including Skyjack, a Canadian listed company, and Brevini, a top company in the field of transmission. Joselito finalized the purchase contract of the hydraulic manifold blocks with AAK in two rounds, and required that AAK hydraulic manifold blocks should not be reported for repair within 1 year. It is not only the hydraulic valves and hydraulic manifold blocks produced by AAK with quality assurance, but also 3 points that are difficult for peers to do well: 1.AAK shall deeply clean the hydraulic manifold blocks before assembly to ensure that it is 100% free of iron filings, dirt and other impurities. 2.Only technicians with more than 10 years of experience are qualified to assemble, check the matching between the duct and the hydraulic schematic diagram, and test the accuracy of each duct to ensure that the sealing ring of the hydraulic valves will not be damaged. After assembly, use the test bench to debug the hydraulic manifold blocks for many times, including pressure test and function test, to ensure that the action function of the circuit is accurate and reliable. Such technicians and such operation procedures may not be found in the 3rd hydraulic valve manufacturer in Ningbo. 3.AAK technical team has engineers from the world's top 500 hydraulic manifold block enterprises. They have their own experience in material selection, production drawing design and production line quality control. AAK hydraulic manifold blocks are not only professional, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak216

Paul is an old customer and also an old friend of ours. He has been purchasing hydraulic cartridge valves from AAK for 7 years. He is a China expert. He used 3 "troubles" in his email on Friday. The thing is, AAK has developed a high- precision hydraulic proportional valve for him, which has already taken 5 months, and cannot fully match the standard parts of HydraForce. Paul is also a bit worried. He knows that if AAK cannot succeed with this hydraulic proportional valve, he can only purchase SUN hydraulic proportional valve standard parts at a higher price of over 70%. His email is as follows: First of all, I apologize for causing AAK in trouble for 5 months. (Paul, very friendly and gentle). What troubles do you have in development? Do you need any help from us? (Paul, very patient and helpful). Don't worry about causing me trouble. If you have a need, just speak up (Paul, very kind and thoughtful). Looking at the 3 troubles in his email, I felt very touched and went back to my childhood. My mother always said to me, "Being in society, try not to cause trouble for others.". My mother is very traditional. Now consider that some Chinese style family education has drawbacks. Parents always educate their children to avoid causing trouble to others outside. From Paul's email, I learned that actually getting into trouble with each other is the beginning of interaction. They trouble each other, but know how to be grateful, and when they come and go, they have a relationship. Over time, this interaction creates an intimate relationship. This is the cornerstone of "mutual trouble, interaction begins". Without gratitude, it is difficult to interact, let alone be intimate. Dare to trouble others, and you may encounter noble people. But the foundation for meeting noble people is to know how to be grateful. The most effective interpersonal communication is to "ask for help" and then give the other person a hidden compliment, potentially acknowledging that the other person is better than yourself. This is an act that everyone instinctively wants and likes to accept. After all, hoping respect, acknowledge, and value from others is the greatest weakness of human nature. But troubling the other person is limited, and you cannot let the other person sacrifice themselves to fulfill you, especially at the beginning of the relationship. This is the red line for "troubling each other and starting interaction.". "Request for help" involves questions that are best dealt with by the other person's expertise and that are a matter of no effort. When the other person has helped, you should immediately express gratitude in full appreciation, making the other person feel that they owe you something. This is the correct attitude in dealing with people. AAK hydraulic cartridge valve, mutual trouble, the start of interaction.

Kearney comes from Türkiye. He had an order for a customized hydraulic manifold with 3μm accuracy that needs to be delivered within 40 days. Due to high accuracy requirement and tight delivery, no manufacturer was willing to accept the order, which is very troublesome for him. At the beginning of this year, their old customer customized a hydraulic power unit, which was quite urgent. The hydraulic manifold for the power unit must be delivered within 40 days. Kearney contacted more than 10 hydraulic manifold manufacturers, but they either could not achieve the accuracy or could not complete it within 40 days. Kearney was very anxious. Kearney found AAK on Google and left a message on AAK website: Can AAK finish a hydraulic manifold with 3μm accuracy within 40 days? At the same time, he provided us the machining drawings of the hydraulic manifold. Although the hydraulic manifold is difficult to process and has high accuracy, AAK has Aigema machining center, and also has the historical experience of completing customized hydraulic manifold test orders in 30-35 days. Kearney saw hope and requested AAK to make samples immediately. 35 days later, AAK sent out 5 hydraulic manifold samples. Yesterday, Kearney sent us an email to place a re-peat order for 100 hydraulic manifolds. Their hydraulic power unit equipment has been recognized by their customer, and their engineers are also satisfied with the accuracy of AAK hydraulic manifolds. Kearney privately told me that his boss praised him for finding a high-quality and efficient manufacturer of hydraulic manifolds in China. This hydraulic manifold is processed by AAK using Taiwan Aigema machining center, which has the advantage of three-axis track and guaranteed accuracy. The setting of dual guide rails ensures that the Z-axis does not shake during rapid movement, ensuring that the machining accuracy is controlled within 3μm. The three-axis movement speed can reach 48M/min, which is more than 50% faster than most machining centers, ensuring that AAK can complete the trial order in 35 days, while the other hydraulic manifold manufacturers in Ningbo China require a delivery time of more than 40 days. This device also has another advantage: it can automatically remove chips. AAK hydraulic manifolds, give you not only 3 benefits. You are welcome to try it out.

At 05:10 this morning, I was listening to music and browsing emails. Billy, who had no news in 9 months, sent an email. Without reading the email, I could guess that the hydraulic check valve developed by AAK for 3 months last year had a result. Opening Billy's e-mail and it is an annual order of 5,000 hydraulic check valves at one time, with about 500 hydraulic check valves delivered every month. Billy is from a hydraulic equipment company in the United States, he has purchased a small number of high-pressure resistant hydraulic check valves from AAK in the past. At the beginning of last year, his company received complaints from a customer that its high-power bulldozers were prone to weak starting of the hydraulic system after being used in less than half a year. The after-sales engineer found that the hydraulic check valves leaked and can not maintain the pressure and caused the problem. Billy contacted the original manufacturer of the hydraulic check valves, and manufacturer advised that the system pressure of the high-power bulldozer exceeded 450bar, and the opening and closing frequency was also high. When the hydraulic check valve was in the high-pressure state above 450bar, the valve spool was worn quickly, and the service life could only be guaranteed as 1 million times. Therefore, it was normal to replace the hydraulic check valves every half a year. If you want a hydraulic check valve with a service life of 2 million times, you can only purchase it from German HAWE. Billy has no choice but to make do with the hydraulic check valves of the original manufacturer first, but the after-sales cost every half a year is really unbearable. Maybe other manufacturers can offer hydraulic check valves with service life more than 1 million times. Billy began to contact other factories, including AAK. After receiving Billy's email, AAK engineers had reached a conclusion according to the hydraulic check valve drawings and bulldozer working parameters. In order to exceed the service life of 2 million times of the hydraulic check valves, we can only test new high-pressure resistant materials. We replied Billy at that time that according to the existing steel options of AAK, what your original manufacturer said was right, it can only guarantee the service life of 1 million times of the hydraulic check valves. However, we are confident to develop the one of 2 million times, because we have our own R & D experience in anti-high pressure. Billy replied directly that AAK would be given 3 months to sample the hydraulic check valves with pressure resistance above 450 bar. He also frankly informed that two other hydraulic check valve manufacturers were also making samples. If all manufacturers fail, they can only buy high-pressure hydraulic check valves from German HAWE. Three months later, AAK successfully sent 20 hydraulic check valve samples to Billy. Nine months later, the email came from Billy today. Billy noted the sample testing results in the email. The bulldozer equipped with AAK hydraulic check valve was still normal after 9 months, while the hydraulic check valves from another two manufacturers were eliminated in the 6th and 8th months. AAK hydraulic check valve has a pressure resistance of more than 450 bar and a service life of more than 2 million times, because: 1.AAK has engineer who have worked in the Shanghai factory of German HAWE for 11 years and has experience in high pressure resistance. 2.We have tested more than 20 kinds of steel and selected the most suitable 35CrMo steel to produce the valve spool of this hydraulic check valve. 3.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%. AAK hydraulic check valve, can resist pressure of more than 450bar, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak215

This week, we’d like to introduce a hydraulic solenoid cartridge valve equivalent to HydraForce SV08-45. It is a solenoid-operated, 4 way, 2 position, direct-acting spool type, screw in hydraulic cartridge valve. In January of 2023, we received an inquiry from a Russian customer for a hydraulic solenoid cartridge valve equivalent to HydraForce SV08-45. Per customer, they have received quotes and samples from several hydraulic cartridge valve manufacturers in Ningbo China. But they are not satisfied either with quality of their product, or with the price level. They hope that AAK can be the one of good combination of reliable quality and reasonable price. After quoting, we were advised that AAK price is not competitive, but they’d like to make a decision after testing the samples. In December, the last month of 2023, we were very happy to know that this customer decided to place the order with AAK. Although AAK price is not competitive, the service life of AAK samples is the longest one among of those hydraulic cartridge valve manufacturers.   AAK hydraulic solenoid cartridge valve E-SV08-45 two advantages: 1. The function and performance is equivalent to that of HydraForce 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-SV08-45 solenoid cartridge valve: Max. Operating Pressure: 207 bar (3000 psi) Flow: 11.4 L Internal Leakage: ＜82ml/min at 207 bar (3000 psi) Cavity: VC08-4 AAK E-SV08-45 hydraulic solenoid cartridge valve, benchmarking HydraForce SV08-45, its service life is 2 times that of its domestic peers. You are welcome to give it a try. AAK HYDRAULIC CARTRIDGE VALVES (759) 2024-01-15 https://www.aakindustry.com/info , -detail/solenoid-valves-aak759

Last Friday, James emailed that he would place an order for 1,200 hydraulic threaded cartridge valves for his last inquiry. This is the PO he sent to AAK after visiting 6 China hydraulic valve factories. It is a little surprised the first cooperation is 1,200 hydraulic threaded cartridge valves. James is from Spain. At the beginning of last year, he was assigned by the headquarters to the Guangzhou office to be responsible for the purchasing from China hydraulic valve factories. In early March, James sent an email saying that the epidemic policy of Ningbo can accept visitors. For the hydraulic threaded cartridge valve quoted last time, the headquarters asked him to visit the China hydraulic valve factories before placing an order. He planned to visit China hydraulic valve factories in Ningbo a few days later. AAK hydraulic valve is his first stop. Three days later, James came to AAK hydraulic valve and asked to visit the workshop directly instead of the office. I took James to visit the whole production line of AAK hydraulic valve, from the first raw material inspection to the processing of hydraulic threaded cartridge valves, including heat treatment of semi-finished products, rough machining, finishing, cleaning, inspection of parts, assembly, inspection, packaging, warehousing and other processes. We also introduced the equipment and processing advantages and characteristics of AAK hydraulic valves. He looked the fixtures modified by ourselves for a long time. Two hours later, James said he would go to other China hydraulic valve factories and left AAK. I'm not sure how many days he stayed in Ningbo and visited how many China hydraulic valve factories. I didn't know about his trip to Ningbo until his email last Friday. He visited 6 China hydraulic valve factories. I asked James why he chose AAK hydraulic valve to place an order after visit 6 China hydraulic valve factories and placed such a large order directly to AAK suddenly. James replied that AAK is the most distinctive China hydraulic valve factory in China he has seen, mainly including the following details: 1、AAK advanced Swiss imported CNC machine tools, honing machines, CNC precision automatic lathes and pressure test bench impressed him deeply, especially those modified fixtures, which have not been seen in other China hydraulic valve factories. 2、AAK has 6 senior engineers in the industry, especially the hydraulic valves in the high-pressure category, with the concept of German HAWE, which makes him feel at ease about quality. AAK inspectors used a strong spotlight to check the valve hole, which made him refreshing. In particular, a few of those whose finish does not meet the requirements are picked out, which shows that AAK is harsh on quality. He has never seen such detailed inspection in other China hydraulic valve factories he visited. 3、Although the hydraulic threaded cartridge valve of AAK is about 10 ~ 20% more expensive than the other 5 China hydraulic valve factories, he believes that the service life of AAK hydraulic valves is 1 ~ 2 times longer than that of them. China hydraulic valve factory, AAK has a cleanliness obsession in quality, which is even more QC than QC. You can also have a small try! https://www.aakindustry.com/info-detai , l/china-hydraulic-valve-factories-aak214

Adam, an old American hydraulic customer, sent AAK 3 emails consecutively on the same day last month, for the leakage of a hydraulic cartridge flow control valve. According to the picture he sent, the hydraulic cartridge flow control valve has a cut-off plate that is supported by a spring. Some customer complained that the hydraulic cartridge flow valve leaked without working. The original manufacturer of the hydraulic cartridge flow control valve cannot solve the problem in 3 months. Because the sales volume of this hydraulic cartridge flow control valve is very good, Adam wants it 100% no complaints. Through the pictures, it is difficult to trace the cause. I suggested Adam send us 3 samples of the original hydraulic cartridge flow control valves. After we received and checked the samples, we found that the leakage was more serious if we pressurized, but the tightness of the cut-off plate was no problem. We adjusted the spring, and the first pressurization did not leak, but after 3 times, the leakage occurred. It was basically judged that the spring has hidden danger. After the spring tension test, it was found that the spring is abnormal. 2 days later, we informed Adam of the hidden danger of the spring, and at the same time, we replaced the internal springs of the 3 hydraulic cartridge flow control valves with AAK springs, and returned the samples to him. 2 weeks later, Adam sent a PO for this hydraulic cartridge flow control valve, with a value of more than 30,000 dollars, and told us that the 3 returned samples were tested for 5 pressurizations, and no leakage was found, and the operating efficiency of the hydraulic system was also improved by nearly 10%. Adam privately ridiculed himself. He has been engaged in the hydraulic valve market for so many years, but still has to ask for help from AAK when there is a problem that he cannot solve. The main reason why AAK can effectively solve the leakage problem caused by springs, is to ensure the following 3 points: 1. We have our own spring source that has cooperated with us for 10 years, to avoid the phenomenon of unequal material between the sample and the production spring, and ensure the quality. 2. Equipped with spring tension and compression tester, reasonably select the spring with elastic coefficient within the standard range, to avoid leakage caused by elastic coefficient deformation. 3. A quality inspection department to ensure that the quality is qualified during assembly and prevent leakage. AAK hydraulic cartridge flow control valve, 3-step check on the spring, zero leakage, welcome to try! https://www.aakindustry.com/info-detai , l/cartridge-flow-control-valves-aak469

For a hydraulic valve manufacturer, if you produce hydraulic valve standard parts like your peers, without your differentiation or difference, you can only rely on a set of hard technical indicators of quality to make the market. I think this is the hard indicator of hydraulic valve manufacturing industry. The first thing for a hydraulic valve factory is quality positioning. I ask our engineers, workshop directors and technicians, even apprentices, to benchmark the global first-line hydraulic valve brands in terms of quality awareness, at least surpassing the quality of domestic first-line hydraulic valves. Otherwise, you are not suitable for hydraulic valve production in AAK. If you don't get the masterly skill really masterly, you are not qualified to enter the hydraulic valve market. With masterly skill, you have the confidence to produce orders for hydraulic valves from the world's top 500 enterprises. “Zhiliang”, also known as “Pinzhi”, is both quality in English. I don't understand why some hydraulic valve manufacturers have no differentiation, and the quality and technical indicators are strong neither. What does it depend on to win the world? Unless you cheat. Each industry has its own quality standards. At the same time, each product has its own enterprise quality standards, and the peers are different. This is the quality positioning. The positioning of AAK hydraulic valves is to benchmark the global first-line hydraulic valve brands. In recent years, AAK has never wanted to recruit new engineers, because it is very difficult to change an engineer's cognition, which takes 18 months, and it will take another 18 months for him to do it, totally 3 years, but maybe he left in the second year, and he had to say something he thought he was right. The manufacturing of hydraulic valves is exquisite. This characteristic is in the upstream of the manufacturing industry - materials, key parts, manufacturing equipment, etc. need long-term investment, continuous tracking and the awareness of excellence, which is also the embodiment of the "craftsman spirit". No matter how iterative the technical cycle of the hydraulic valve is, your skills must not age, the craftsman spirit must not be lost, and the masterly skill must be really masterly. The road of quality is just like practice Buddhism or Taoism. The practice of good people has to go through thousands of risks and obstacles, same as the difficulty of eighty adventurous experiences before Tang Sanzang finally got the real Buddhi , st scripture. In the first few years of AAK hydraulic valves, we had to take a detour. There are a lot of south walls to hit, pits to fall and tuition fees to pay. Maybe this is the growth of AAK. Growth is as painful as death, and the essence is also the same as death. It means the disappearance of old quality standards and the birth of new quality standards. Accept it, face it. Then, we can constantly upgrade and grow into what we expect. AAK hydraulic valves, quality is the highest principle. https://www.aakindustry.com/info-detail/hy , draulic-valves-aak213

A few days ago, Jackson, who is engaged in hydraulic manifolds procurement from Honeywell, one of the world's top 500 companies, asked me a question. Can you sum up the differences between AAK hydraulic manifolds and other China hydraulic manifold manufacturers in one sentence? Without thinking, I told him about 3 points: learn from the advanced, be close to the “rich”, and follow the right path ". The 13 years of AAK hydraulic manifolds relies on adhering to these 3 points. To learn from the advanced, first of all, we should be good at learning from excellent peers, especially from the leading international brands. I warn my engineers that we do not pursue the most advanced technology, but we must be close to advanced enterprises, and take stability and reliability as our lifeline. Various types of hydraulic cartridge valves are the core components of hydraulic manifolds. SUN, HydraForce and HAWE etc, these No. 1 brands in the mass market or the niche market, are the target of AAK's learning and benchmarking. We often dissect their new models, learn design, refine elements, analyze process, optimize technology, and gradually form a complete AAK hydraulic manifold system from the original design, processing drawings, material selection, material heat treatment, process sheet, processing technology, assembly, and testing. Be close to the “rich”, cooperate with the strong, and cooperate with the world's top 500. They are interested in the manufacturing quality, function reliability and performance stability of your hydraulic manifolds. They talk to you about quality and service in a comfortable way, then you have more motivation and responsibility. It also contributed to AAK's willingness to invest in R&D, equipment iteration and talent introduction, and gradually became a strong player. Follow the right path. If there is a shortcut in manufacturing, taking the right path is the only shortcut. This is not only a long-term principle, but also a way to avoid detours, which is also the core of continuous operation of manufacturing enterprises. To do something and not to do something is to be a hero. If you tell a lie, you need to tell at least 10 more lies to cover the original lie, which is too tired and annoying. Drug dealers and arms dealers must earn a lot of money, but we can't do it. What good is it to do something that has no positive significance to society? There are universal axioms and universally recognized moral bottom lines in this world. No matter what industry and product an enterprise is in, it should follow these axioms and bottom lines. Google's business philosophy of "Do not be evil" is very reasonable. Many enterprises believe that "strength is the truth". They believe that with the support of capital, market input regardless of cost, and consumers fooling, they can achieve huge sales and profits. They believe that with market share, users will cater to them. In fact, this is to begin at the wrong end. Only your manufacturing quality continues to benchmark the authoritative brands, and the reliability of the function and the stability of the performance, adhere to the right path, not be impatient, is the source power. It is hard to engage in manufacturing industry, especially the hydraulic unit, the hydraulic manifold with technology, which is slower, more stupid and more solid than others. It is the smart people who make toil efforts. There is no shortcut to this road. There is no safe haven. Without “1”, the manufacturing quality takes the lead in the front, any more 0 after will eventually return to zero. Just like life, whether you can stand on the waves, and whether you can hold on the bottom of the waves. The manufacturing quality of hydraulic manifolds relies in slower, more stupid and more solid work of intelligent people. There is no shortcut to this road. There is no safe haven. Without “1”, the manufacturing quality takes the lead in the front, any more 0 after will eventually return to zero. Just like life, whether you can stand on the waves, and whether you can hold on the bottom of the waves. AAK hydraulic manifolds, learning from the advanced, close to the “rich”, and taking the right path, we will move forward together. https://www.aakindustry.com/info- , detail/hydraulic-manifolds-aak401

Eugenia comes from Greece, and has been smooth on purchasing for 5 years. Unexpectedly, due to a hydraulic manifold, she was in a trouble. At the beginning of this year, their company developed a hydraulic station for elevator lifting systems for the first time, which requires hydraulic manifold. Eugenia chose a manufacturer that has been cooperating for over 3 years to make samples, and the sample testing went through smoothly. The first batch of 50 hydraulic stations, after 2 months of operation, occasionally experienced abnormal elevator operation. The after-sales engineer found that there was a leak in the hydraulic manifold within the system, and some pressure control cartridge valves have hysteresis in opening and closing. Per the manufacturer of the hydraulic manifold, it is normal for individual abnormalities and it can be replaced for free. However, the customer is not satisfied and requested to ensure that each hydraulic manifold is 100% normal within 12 months. Eugenia became anxious. Eugenia found AAK on Google and left a message on AAK website: Can AAK ensure no abnormalities within 12 months for the hydraulic manifold on the elevator lifting system hydraulic station? After communication, it was learned that the manufacturer he placed the order with is not specialized on the production of the hydraulic manifolds for elevator lifting systems. Eugenia is surprised to ask, “Does this require a dedicated factory to produce?” I told her that although the production process of hydraulic manifolds is the same, the testing process is completely different. I sent him a video of AAK's dedicated hydraulic manifold testing for elevator lifting system hydraulic stations, and also included the case of AAK's previous solution for Russian customers on elevator lifting system hydraulic stations. The next day, Eugenia sent us the complete hydraulic manifold drawings and the working principle diagram of the entire hydraulic station. It took less than 1 week for AAK to provide modification suggestions, quotations and receive the PO for the hydraulic manifolds. For the hydraulic manifolds used on the hydraulic station of the elevator lifting system, AAK not only considers the function and stability of hydraulic manifolds in material selection and manufacturing accuracy, but also the most important is the testing. AAK has a self-developed elevator hydraulic station testing system that directly simulates elevator on-site work. Before shipment, each hydraulic manifold undergoes functional testing. Firstly, the system pressure will be set to 31.5Mpa. When the elevator up button is pressed, the elevator will automatically and smoothly run up to the designated position and stop. When the elevator down button is pressed, the elevator will automatically and smoothly descend to a fixed position. The trick inside this is that the hydraulic manifold has stepless speed regulation, small reversing impact, and the service life of the hydraulic system is protected. AAK hydraulic manifold used in elevators, with proprietary testing equipment, and is safe in 12 months, you can also give it a try!

What should hydraulic cartridge valve manufacturers do to convince potential customers? AAK, a hydraulic cartridge valve manufacturer in China, has 13 years of foreign trade experience and summarized 3 sentences: there is warmth in communication, strength in work, and accuracy in feedback. I have seen some sales person of hydraulic cartridge valve manufacturers, when communicating with customers, they answer questions one by one, just like a robot from beginning to end. The customers can't feel any fun or warmth from them. Customers don't like to hear what they said either. As a hydraulic cartridge valve manufacturer, you have become a second choice. Communication with temperature between hydraulic cartridge valve manufacturers and customers is nothing but two. The first is sincerity. Sincerity means that hydraulic cartridge valve manufacturers are sincere and consistent, not just hypocritical and polite, but need to have empathy and not view others' choices from their own perspective. The second one is tolerance. Customers are also human and can make mistakes. Hydraulic cartridge valve manufacturers need to have a tolerant heart, and the premise of tolerance is that you first learn to think from the other person's perspective and think from their perspective. Find out why he asked that? What is his purpose in saying these words? Looking at problems from a different perspective, understanding and being tolerant, makes it easier to achieve communication goals. Communication should have warmth, and communication should start from the heart. The strength of hydraulic cartridge valve manufacturers often determines the success or failure of their work. Before starting work, the plan of the hydraulic cartridge valve manufacturer must be meticulous and comprehensive. What is your plan for the customer and the best path to achieve it. A good plan is often the beginning when customers believe in you, the beginning of success. But no matter how good the plan is, without action, everything is equal to zero. If the hydraulic cartridge valve manufacturer does not make every effort and does not execute it properly, then the result is discounted. We must have an attitude of never giving up until we reach our goals. No matter what hydraulic cartridge valve manufacturers provide to customers, the most important thing is to have results. If there is no result in doing something, it is equivalent to doing it in vain. Of course, customers will not believe you. However, all results have causality. What causes hydraulic cartridge valve manufacturers plant, what results they produce. Feedback is accurate. We must provide customers timely feedback on what they are concerned about. Feedback must be accurate, relevant, and constructive. These feedbacks can make customers feel the progress, professionalism, service of the hydraulic cartridge valve manufacturer, and give customers the sense of safety. Even if the hydraulic cartridge valve manufacturer makes a mistake, it is necessary to provide truthful feedback. To discover the real problem and provide the most effective feedback. A good feedback may lead to a completely new action plan. Hydraulic cartridge valve manufacturer AAK, adheres to 3 levels of service: warmth in communication, strength in work, and accuracy in feedback.

AAK hydraulic cartridge valves are inseparable from interacting with different people in terms of production, promotion, marketing, and sales. Especially in the sales segment, a good sales of hydraulic cartridge valves not only takes more orders, but also makes customers feel comfortable. The person that everyone attaches the most importance to is themselves, so how to be themselves and store the value of the other party. The most important thing is to avoid using "me" too much and try to use "you" instead. Put the other person in the position of the subject and define yourself as the object. For example, AAK has provided customer with an optimization plan for "hydraulic cartridge valves", although we are very confident, if you say, "As you know, my plan is definitely effective." This would confuse each other's positions. You can replace this sentence with, "With your efforts, this optimization plan will definitely work.". This conversation is very comfortable. For example, AAK provides customers with a suggestion on the use of hydraulic cartridge valves. If you say, "Do as I say, it's definitely right." This is very hard. You can replace this sentence with: If you give it a try, you'll be pleasantly surprised. Customers will spontaneously adopt such suggestions. For example, the customer has a tight time frame to develop a new hydraulic cartridge valve, and there is little time left for AAK. AAK urgently needs the customer's drawings and detailed instructions. If you say, "I request that they be received tomorrow," you can replace this sentence with: If you can help me deliver it tomorrow, this matter will be successful. With this expression, the customer will be very proactive in following up. When communicating with others, never talk to yourself. Don't be self centered in what you say. Be sure to relate to the person who listens. If it has nothing to do with the obedient person, there is no need to say this, because people have no interest in what you say. Some people say, is it tiring to communicate like this? Your groundbreaking skills are only basic skills of others, so of course you are tired. In the business of hydraulic cartridge valves, everyone wants to make money. Behind the money is something, and if things are done in detail, money will naturally come. The person behind the matter is responsible for doing it well and making the other person comfortable, and the matter naturally becomes a reality. Behind a person's back is fate. With a good heart, doing good deeds and practicing along the way, there is naturally a good fate. Behind life is the Tao, with a heart that has the other side and a heart that takes the right path. That is the Tao. Whether it is a hydraulic cartridge valve manufacturer, or a businessman who purchases hydraulic cartridge valves, whether it's work or life, Life is about serving, making money is incidental and determined. If the purpose of life is to make money, bankruptcy is incidental and doomed. AAK hydraulic cartridge valve, focuses on manufacturing quality, function, performance, and serving others.
