Devante is from a Spanish hydraulic equipment manufacturing company, and has been engaged in procurement for more than 5 years. Last February, they upgraded an injection molding machine, focusing on the selling point of "high speed when empty, low speed when heavy load". The engineer asked Devante to purchase the hydraulic cartridge proportional needle valve of HydraForce. During the equipment commissioning, it was found that the pressure relief and flow of the hydraulic system of the equipment was conflicted with the hydraulic cartridge proportional needle valve, resulting in unstable operation of the equipment and jitter. HydraForce said that there was no time to customize the hydraulic cartridge proportional needle valve. Devante contacted several cartridge valve manufacturers and had no news. Devante was very worried. Devante browsed AAK website on Google and left a message: 1. Can AAK customize the hydraulic cartridge proportional needle valve, and the performance benchmarking HydraForce? 2. The function of smooth flow passage is required. 3. The function of variable flow gain is required. At the beginning, I thought that he was requested for AAK hydraulic cartridge proportional needle valve to benchmark the standard parts of HydraForce, but it was turned out that he needed us to optimize the standard parts of HydraForce. According to the equipment abnormality video, the original hydraulic cartridge proportional needle valve drawing, and their required functions sent by Devante, after discussion, AAK engineers was 90% confident. Devante asked AAK to make samples. After 40 days, AAK sent 15 samples of cartridge proportional needle valves. 2 months later, Devante informed that the market promotion of the upgraded equipment was smooth. Their engineers were satisfied with AAK hydraulic cartridge proportional needle valves, especially its variable flow gain characteristics, and smooth flow characteristics, small pressure impact during pressure relief, and accurate flow control. We mainly made 3 ingenious actions on the valve housing and valve spool, and solved the problem that HydraForce didn't want to do. 1. The lower part of the valve spool is arranged in the valve housing and sealed with the valve housing line. The upper part of the valve spool is connected with the control cover plate, the upper end of the control cover plate is connected with the valve cover with threaded holes, and the displacement sensor is installed on the threaded holes of the valve cover. The lower end of the valve spool is connected with the upper cavity of the valve spool. When the valve spool is at the lowest end, the valve is closed. When the valve spool moves upward, the valve gradually opens. 2. The lower end of the valve spool bottom is equipped with a semicircular slotted orifice. When the valve opening is small, the flow gain is small, and has good linearity, small flow, and high-precision linear control. When the valve opening is large, the flow gain is large, and it has good linearity, large flow and high-precision linear control to ensure the variable flow gain function of the hydraulic cartridge proportional needle valve. 3. The valve housing is provided with 4 symmetrical waist-shaped holes, replacing the conventional round holes. The oil flows in from the lower port of the valve spool and flows out through the waist hole, reducing the pressure impact and speed sudden change of the oil near the valve port of the hydraulic cartridge proportional needle valve, and realizing the function of smooth flow. AAK hydraulic cartridge proportional needle valve, has dual functions of variable flow gain and smooth flow.

There is a spread in the hydraulic valve industry: those who can do a good job in hydraulic valves may not be able to do a good job in hydraulic manifolds; those who do a good job in hydraulic manifolds, and basically can do a good job in hydraulic valves. Baptiste is from DMH France. The hydraulic manifolds purchased in Italy before was transferred to the hydraulic valve manufacturer who has cooperated for 4 years. However, he suffered from the 4 times a year after-sales of hydraulic manifolds. In the second half of last year, Baptiste purchased 30 hydraulic relief valves from AAK, which is the 4th time of purchasing in the year, and the quantity is the same every time. It is a little strange. After communication, I learned that a hydraulic equipment developed by them at the beginning of last year has stains on the hydraulic oil every few months, resulting in the jamming of the hydraulic relief valves. The replacement of 4 times a year keeps the customer complaining. According to Baptiste's description, the probability is that the hydraulic manifold design is improper. I suggested that he send us the hydraulic manifold drawing and system schematic diagram. Baptiste said that the hydraulic manifold drawing and system schematic diagram are confidential documents and he must get approval from boss before sending them to AAK. Three days later, Baptiste sent us the hydraulic manifold drawing and system schematic diagram, requiring that they should not be revealed to any other people. According to the analysis of the drawings, AAK engineers found that when the hydraulic power is input and the system does not start working, the hydraulic relief valve does not reach the opening pressure and cannot relieve the pressure, resulting in the increase of oil temperature and easy oil pollution. It is certain that the problem lies in the design of hydraulic manifold. I suggest redesigning the hydraulic manifold. The idea is as follows: AAK will change the 2 hydraulic relief valves on the hydraulic manifold block to use the hydraulic directional control valve alone, and change the oil circuit design. The principle is as follows: when the hydraulic system works, the hydraulic directional control valve cuts off the oil circuit, making the high-pressure oil enter the working branch. When the hydraulic system stops working, the high-pressure oil directly returns to the oil tank after passing through the directional control valve to realize zero pressure unloading. If the hydraulic manifold designed by AAK is not improved, no fee will be charged. Baptiste was a little interested after learning that. 45 days later, AAK sent a new hydraulic manifold. 4 weeks later, Baptiste informed by email that the hydraulic manifold of AAK had been used for 1 month, the hydraulic oil had no pollution, the whole hydraulic system was more sensitive, and the problem that had plagued them for 1 year was solved at one time. AAK hydraulic manifolds had been tested for first-line brands since 7 years ago. If meeting the following 3 points at the same time, there may be no second hydraulic manifold manufacturer in Ningbo except for AAK: 1. AAK technical team has engineers from the world's top 500 hydraulic manifold enterprises. They have their own experience in material selection, production drawing design, oil circuit design and production quality control. 2. Before hydraulic manifold assembly, the valve block shall be deeply cleaned to ensure 100% impurity free. Each valve shall be tested. 3. Only technicians with more than 10 years of experience are qualified to assemble the hydraulic manifolds. After assembly, use the test bench to debug the hydraulic manifolds for many times to ensure that the act function of the circuit is accurate and reliable. Baptiste privately informed that the boss was very satisfied that he found a reliable hydraulic manifold manufacturer, solved the after-sales troubles of the whole year, and could be promoted to the manager of the procurement department next month. Baptiste was so happy. AAK hydraulic manifold block is professionally designed to save you worry and effort. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak230

Harold is from Peru and specializes in hydraulic logistics equipment. In the second half of last year, they developed a lift that experienced shaking and impact when the load was lowered. Their engineer determined that the hydraulic cartridge counterbalance valve was not satisfactory and requested the original manufacturer to improve its function, but the other party gave up. Harold spent 3 months with this hydraulic counterbalance cartridge valve manufacturer from inquiry to sample, which made him very discouraged. Harold found AAK hydraulic cartridge valves on Google search and noticed that AAK has introduced some customer cases about the solution for difficult and complex hydraulic counterbalance valves. He asked via email: Can AAK hydraulic counterbalance valves solve system shaking and impact phenomena? After communication, it was learned that he had encountered difficulties in purchasing hydraulic counterbalance valves. In fact, this is a common problem, which is likely caused by sudden changes in the flow area of the valve port, resulting in low-frequency vibration and impact. Based on his original anatomy, it's the same as what I guessed. As long as the hydraulic counterbalance valve is set with a buffering function, it can be solved. After 50 days, AAK sent 20 samples of hydraulic counterbalance valves. Harold, 3 months after the sample of the hydraulic counterbalance valve was sent out, brought me good news. This morning, when I opened my email, I saw his PO for 200 hydraulic counterbalance valves. Their engineers are very satisfied with the buffering function of AAK hydraulic counterbalance valve, and the load shedding is stable, without shaking or impact. Just like this, the additional function of AAK hydraulic counterbalance valve brings 2 advantages to his equipment. AAK does this by creating grooves on the main valve spool of the hydraulic counterbalance valve to accurately control the flow area. When the load drops, it is controlled by a gentle throttle and can also quickly buffer the impact pressure. 1. The main valve body of the AAK hydraulic counterbalance valve has a fixed first valve seat, and one end of the main valve spool is connected to the first valve seat, which slides and fits with the main valve body. The inner chamber of the main valve body is divided into the first and second chambers connected to the oil inlet, as well as the control chamber. 2. The second chamber is equipped with a second valve seat and elastic components. When the oil enters the oil inlet, the oil pushes open the second valve seat and flows to the oil outlet. The elastic component presses the steel ball onto the flow channel port inside the main valve spool through the spring seat. 3. There are multiple U-shaped grooves along the axial direction on the circumferential surface of the main valve spool, and the key lies in the depth, width, and distance between the grooves and the steel ball. AAK hydraulic cartridge counterbalance valve, has 1 additional function compared to its peers, and you can also give it a try!

Elijah is from a Canadian hydraulic equipment manufacturing company. At the beginning of this year, he encountered trouble. A batch of excavators sold by his company to Southeast Asia needed to replace the hydraulic directional valves. The main reason is that the hydraulic directional valves have been used for a long time, and it is time to replace them. The trouble is that these non- standard hydraulic directional valves from HydraForce in the United States were out of stock at the end of last year, and Elijah did not fill the inventory in time. Elijah urgently contacted the original hydraulic directional valve supplier, because these hydraulic directional valves are non-standard and were produced 2 years ago, the original supplier has no inventory now. If they are customized again, 1,000 MOQ will be required, and the production time will be 2months. Elijah fed back the information to the boss, who was angry because 60% of their company's orders came from this customer every year, and Elijah had a big headache. In order to solve the problem of time, Elijah tried to contact the hydraulic directional valve manufacturers close to Southeast Asia. The hydraulic directional valve manufacturers in China are his first choice. Elijah found AAK hydraulic valve on Google. After receiving the email, we compared the hydraulic directional valve drawings provided by Elijah. This hydraulic directional valve is not a conventional product, but he only gave a delivery time of 30 days, and the quality of hydraulic directional valve must be compared with that of HydraForce. We are worried about not the quality requirements, but the production time. Due to the particularity of this hydraulic directional valve, the process design and programming need a lot of time to complete the matching. In addition, the heat treatment and surface treatment of parts, assembly inspection and commissioning and other processes all need time. Elijah had to bite the bullet and accept our request for 40 days of delivery time. Fortunately, the design and production of this hydraulic directional valve were very smooth. 30 days later, AAK sent 50 hydraulic directional valves to Elijah's Southeast Asian factory. A few days ago, Elijah sent an email to thank AAK. Fortunately, AAK hydraulic directional valves helped him solve his urgent need. Elijah asked us how we did it. He successively contacted more than 20 hydraulic directional valve manufacturers. They all fed back that either the delivery time was too short or the quality could not be benchmarked with HydraForce. AAK is the only Chinese hydraulic directional valve manufacturer, who promised that the quality would be benchmarked with HydraForce, and the delivery date is also within 30 days. I told him that for this non-standard hydraulic directional valve, AAK has 3 points that are difficult for the other manufacturers to match with: 1.AAK is a supplier of HydraForce for 9 consecutive years, and the quality benchmarked Hydraforce is the least worth mentioning guarantee. 2.We have a high-efficiency MIKRON machining center and AMEC sinking drilling and milling cutter with central internal cooling, which allows faster cutting. In this way, human errors are eliminated in accuracy and efficient production is ensured. 3.AAK has been ODM manufacturer for 3 Fortune 500 companies for 10 years, with strict quality control process and self-implementation stricter than ISO certification system, and never relax the requirements to ourselves, stick to the details and constantly optimize the technology. AAK hydraulic directional valve is the first choice for customers in North America. You are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-valves-aak229

Wagner from Germany has been communicating with hydraulic manifold manufacturer AAK via email for 3 months. He has sent 4 inquiries and we sent 2 samples. He was very satisfied with the service and communication of hydraulic manifold manufacturer AAK, as well as the manufacturing quality of the hydraulic cartridge valves and hydraulic manifolds. In early October, Wagner said he was going on a business trip to Shanghai and specifically came to Ningbo to visit the hydraulic manifold manufacturer AAK. I know that Wagner and AAK have reached a level of trust, and the order is expected next.   At 2:30 pm on October 27th, it was Wagner's arrival time at the hydraulic manifold manufacturer AAK. At 2:00 pm, I went to the conference room to check and found that there were no lights on, no fruit trays, or projectors. I asked my colleague A, and A's answer was: all of these are ready, but they have not been moved to the conference room yet. There is still half an hour left, and there are no problems in time, so you can rest assured.   After arriving at hydraulic manifold manufacturer AAK, Wagner went directly to the production workshop. 45 minutes later, he arrived at the conference room with satisfaction and a smile. All the necessary things for the meeting are ready. Colleague A opened the projector and prepared a detailed introduction of the hydraulic manifold manufacturer AAK. However, the projector couldn't be connected and it was still not done after 5 minutes. We could only use paper materials to introduce it. I also noticed that Wagner's smile was also reduced, and I realized that he cares about every detail very much. After Wagner's factory visit, although there were still email communication, no orders were placed. From the detail issue of projector, Wagner is concerned that the team did not act proactively.   If it was done 1 hour in advance and discovered a problem with the projector, it may take only half an hour to solve it, rather than reaching the cutoff point and can not resolve it. This leaves no room for oneself. For those engaged in the manufacturing industry of hydraulic manifold manufacturers, they need to consider the possibility of unexpected situations and the required room, which is what makes them adept. The cooperation between hydraulic manifold manufacturers and customers cannot always be smooth. The key is to solve it before the deadline, which is reliable. In fact, the team is the same. I entrusted the matter to my partner, once it was fine, twice it was fine, and three times it was okay. This way, I felt at ease and my trust with him was built. However, after a low-level mistake occurred once, this trust would break. Establishing trust is difficult, but it is easy to collapse.   The development momentum of hydraulic manifold manufacturer AAK is still very good, and I am racing all the way. I particularly need my partners to grow and keep up with my pace. If they don't grow and can't keep up with our footsteps, there will be break. In this situation, either I stop and slowly walk with them. Either my partners grow up closely with me and don't fall behind.   Hydraulic manifold manufacturer AAK is a team, and everyone must help and add color to this team, rather than adding obstacles. There are no small matters in production, and similarly, there are no small matters in sales. In fact, there are no small matters in every link. Grasping details, checking in advance, making predictions, and having plans are also the basic qualities of sales. To do business, it is necessary to have prior knowledge and foresight. Preparedness ensures success, unpreparedness spells failure. Early Birds Catching Worms. This is an important principle for us to do things. If the customer feels that we are not trustworthy and not keeping our promises, then they will not work with us. Hydraulic manifold manufacturer AAK in Ningbo China, be the early birds.

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

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

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

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

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

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

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

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

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