Domestic large aircraft C919 is put into market at unit price of 99 million US dollars. Most of the performance indicators of C919 are the same as those of Airbus A320 and Boeing 737. In the future of manufacturing industry, labor-intensive factories will be eliminated. Instead, they will focus on manufacturers with certain technical content to benchmark or gradually surpass international first-line brands. This is also the trend for hydraulic valve manufacturers.
Change the design of hydraulic directional control valve, the vibration disappears, and AAK eliminated Canadian factory at zero cost Hunter is an old purchaser of EAGLE PRO company in Canada. It has been several years since he purchased hydraulic directional control valves from AAK. In the second half of last year, Hunter emailed that he would become the general manager of Hangzhou branch in a month and visit AAK. Hunter has been engaged in procurement for 5 or 6 years. This promotion must be due to outstanding contributions. Some time ago, their company developed a batch of hydraulic cylinders, which vibrated greatly during commissioning. Their engineer thought that there was a problem with the hydraulic directional control valve, but the hydraulic directional control valve was normal when tested separately. The engineer was confused, and the boss was also very anxious. He asked hunter to consult the manufacturer of hydraulic directional control valves. This hydraulic directional control valve is produced by a local factory in Canada. After on-site analysis, the engineer of the original factory thinks that the vibration is caused by the sharp change of oil port pressure during the reversing of the hydraulic directional control valve. It can be solved by changing the hydraulic manifold design. The engineer's scheme is to connect two small adjustable one-way throttle valves in series on the control oil circuit at both ends of the hydraulic direction control valve. After 20 days, according to the plan of the original hydraulic directional control valve manufacturer, there was no vibration. The boss was very happy and let Hunter be promoted. Knowing that the installation of two throttle valves has increased their cost by 20%, I wonder if there is any other scheme. After getting their hydraulic direction control valve drawings, hydraulic manifold drawings and the hydraulic schematic diagram of the system, AAK engineers began to analyze. Three days later, AAK's scheme came out. The shoulder of the hydraulic directional control valve spool table was redesigned and a triangular throttling groove was added to avoid the sharp change of oil port pressure during reversing. This new design does not change the production cost of the hydraulic directional control valve, that is, it solves the vibration at zero cost. Hunter was a little incredible and asked AAK to immediately sample the new hydraulic direction control valve. One month later, the hydraulic directional control valve of AAK sample was sent out. After commissioning, there is no vibration, but the cost is zero. Hunter's boss happily saved 20% of the cost and asked hunter to always send inquiry for any hydraulic directional control valves to AAK at the first time. The design of hydraulic directional control valve runs through the whole process of design, manufacturing, use and maintenance. A good hydraulic directional control valve design cannot be separated from manufacturing.
defines total quality from 4 aspects, which is the first time in the hydraulic valve industry I want to know how defines the quality of hydraulic valves. I specially checked the IP, which is an engineer from an engineering company listed in the I thought for half an hour. To define a category, it must be comprehensive. What are the total quality of hydraulic valves How much do we understand the quality of hydraulic valves First, don't check the encyclopedia, , or hydraulic valve academic, but focus on hydraulic valve common sense. In common sense, how do you understand the quality of hydraulic valves, because our users also understand the quality with common sense. Friends who have read science and engineering know that there is a very famous management in What is carried forward is in . The well-known enterprises implement total quality management. Almost all those engaged in manufacturing industry know total quality management, but few mention total quality. Some people say that total quality management has talked about total quality Wrong, total quality management does not talk about total quality, only about management. For the total quality of hydraulic valves, I have defined 4 kinds of quality. The 1st is the manufacturing quality of hydraulic valves, the 2nd is the service quality of , the 3rd is the functional quality of hydraulic valves, and the 4th is the performance quality of hydraulic valves. The manufacturing quality of hydraulic valves is now benchmarked with the international first-line brand, and the future is to surpass the international first-line brand. Especially in a subdivision field, such as high-pressure hydraulic valves, we should achieve top 1%. 1. has been hydraulic valve ODM manufacturer for 3 of the world's top 500 for 10 years. The quality control process is strict and self-implementation is more strict than ISO certification system. 2. has high-precision machine tools imported GF high-precision CNC machining center and GILDEMEISTER turn milling compound machining center. 3. has a full-time material engineer to check the selection of materials, which is responsible for screening, comparison, testing new materials connected with the Research Institute. technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in production drawing design, programming and production line quality control. Service quality of : 1. provides 24-hour responses, 48-hour solution plans and 72-hour problem solved before, during and after sales. Our peers dare to think but dare not to do it.
The old customer in the Netherlands who did not change the factory easily failed again and again. AAK hydraulic relief valves settled it at one time Marten is an old customer from a Dutch hydraulic company. He is very cautious in the business of hydraulic valves and never changes hydraulic valve suppliers easily. AAK hydraulic valve reached the first cooperation of hydraulic relief valves under the introduction of his friend. It has been 3 years, and he orders 2 types of hydraulic relief valves with AAK every year. We have a very good personal relationship, and often communicate about some hydraulic valve technology. Last month, Marten had an order for a special hydraulic relief valve that requires a surface roughness Ra of 0.1~0.2�¼m, which is more than 4 times accurate than the normal standard. All the hydraulic relief valves of this series are purchased from the hydraulic valve manufacturer that he has cooperated with for 5 years. This manufacturer has tried this hydraulic relief valve for 3 consecutive times, but the Ra value is still not up to standard. Marten thinks of AAK hydraulic valve. In the email, he has been emphasized that the surface roughness Ra value of hydraulic relief valve must reach 0.1~0.2�¼m. According to the hydraulic relief valve drawings sent by Marten, after discussion, AAK engineers expressed 90% certainty that the Ra value could reach 0.1~0.2�¼m. Marten seems to see hope, but also fear. He asked AAK TO try samples immediately. At the same time, the original hydraulic relief valve manufacturer was also requested to continue the sampling. AAK arranged the most experienced technicians to operate the knife, first of all in the rough turning stage, cutting depth adjustment to 0.8~1.5mm, feed to 0.2~0.3mm/r, cutting speed to 30~50m/min and so on, after the rough turning Ra value is 12.5~6.3�¼m, while leaving 0.5~1mm as fine turning margin; Secondly, in the finishing stage, the cutting depth is adjusted to 0.1-0.3mm and the small feed is 0.05-0.2mm /r. At the same time, the cutting speed is ensured to reach the moderate value and the roughness Ra value is ensured to reach 0.2-0.16�¼m. AAK sent the hydraulic relief valve samples 10 days later. On the 3rd day after receiving the samples of AAK hydraulic relief valve, Marten informed us by email that the Ra value of the surface roughness was up to standard. At the same time, he also informed that the original hydraulic relief valve manufacturer also continued the sampling, but failed in 5 samples for 5 times, while AAK succeeded in one time. He asked us to catch time to prepare material, he would discuss the PO of hydraulic relief valve with AAK after he confirmed the order quantity and the delivery date with his customer. For high precision hydraulic relief valve roughness Ra value, in addition to use high precision lathes, good technicians are the key, to be good at adjusting lathe parameters according to different
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 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 manufacturers, and the quotation of some hydraulic relief valve manufacturers is 60% cheaper than that of 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 to send samples, because the price of 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. offers the highest price, but it is still about 30% cheaper than manufacturer. At the same time, promised that the quality could fully match that of manufacturer. According to the hydraulic relief valve drawings and working condition information provided by Rodriguez, sent the samples of the hydraulic relief valves after 25 days. A month later, Rodriguez sent an email that hydraulic relief valves passed the test, and the parameters were benchmarked with those of the original manufacturer, and even some details and appearance were visually more exquisite than those of the manufacturer. He would like to know how makes hydraulic relief valves that surpass American manufacturers has a high-precision CNC machining center imported from 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.
AAK hydraulic valve can make ignorant mistakes, but it can't make arrogant mistakes 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. AAK HYDRAULIC VALVES (227) 2022-05-15
AAK never cheat in 13 years, and has become the ODM factory of top 10 hydraulic valve brands in the world 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".
Jone is a hydraulic customer from the United States. His company has recently developed a hydraulic relief valve suitable for machines with high impact and high load. Because of the high requirements of working conditions, the steel used for the hydraulic relief valve has not been approved yet. They have been testing in the local hydraulic relief valve manufacturers in the United States for several weeks. Due to the high cost of proofing in the United States, they want to turn to Chinese hydraulic relief valve manufacturers for sampling and testing. Jone compared more than 10 hydraulic relief valve manufacturers and selected 3 to make samples. After receiving and testing the samples of hydraulic relief valves, none of them can meet the requirements of service conditions, and the test results are much worse than those of local manufacturers in the United States. Although these 3 hydraulic relief valve manufacturers changed the materials and improved the parameters, the toughness and plasticity of the steel still did not meet the working conditions, and Jone and his team were at a loss what to do. His friend Tom recommended him to contact AAK hydraulic valve for a try. Jone sent us an email with a try attitude. According to his hydraulic relief valve drawings and the working conditions with large impact force and high load, our engineers were not 100% sure, but were 90% sure, giving 2-3 weeks. Two weeks later, AAK successfully sent 6 hydraulic relief valve samples. On the 3rd day after Jone received the hydraulic relief valve samples, we received an email that the samples of hydraulic relief valve passed the performance test. AAK spent 2 weeks to try over 10 kinds of steels, and finally determined to replace 40Cr with 35CrMo steel. The high toughness and plasticity parameters of 35CrMo well match the working conditions of this hydraulic relief valve. At the same time, 35CrMo has high static strength, impact toughness and high fatigue limit, and the long-term working temperature can reach 500 . Jone was surprised that the samples of more than 10 hydraulic relief valve manufacturers in China were not successful. Even if the local manufacturers in the United States spent 4 weeks but still failed, how can AAK succeed in 2 weeks one time? The reason why AAK hydraulic relief valves can do what the domestic factories in the United States failed to do, because: 1. AAK has full-time material engineer who is specially responsible for material screening, comparison, testing and docking with the materials research institute. 2. Good materials also need good processing. The heat treatment method adopted by AAK for 35CrMo alloy steel is 845 annealing, 860 quenching (oil quenching) and 200 low-temperature tempering. After this special heat treatment, its hardness and wear resistance are increased by at least 50%.
For high pressure hydraulic needle valves that can benchmark Germany HAWE, AAK is the only manufacturer in Ningbo This morning, I received the order of 2,000 hydraulic needle valves from Charlotte. At first, I thought she sent the email by mistake, because Charlotte had no cooperation with AAK, we just discussed the inquiry for her hydraulic needle valve with pressure resistance of 450bar for 3 times. It is the first time I met a hydraulic valve customer who placed a big order after 3 times of communication. I asked her directly why she gave AAK such a large quantity of hydraulic needle valves order in only the first cooperation. Charlotte said that this hydraulic needle valve was purchased from HAWE in Germany 3 years ago, because HAWE is the best manufacturer of high-pressure hydraulic valves in the world. Charlotte is from a hydraulic equipment company in Spain. Last month, their company tried to purchase this high-pressure hydraulic needle valve from Ningbo, which is the hometown of hydraulic valves in China. She has a hydraulic valve supplier who has cooperated for 5 years and has high mutual trust. Due to the special requirements and urgent delivery date of this hydraulic needle valve, the original hydraulic valve supplier was unable to bear it, so he suggested Charlotte contact AAK, and joked that if AAK could not complete this hydraulic needle valve, she should not waste more time in Ningbo, but go back to HAWE to purchase the high-pressure hydraulic needle valves. I received the drawings and working condition requirements from Charlotte. This customized hydraulic needle valve is applied to aviation equipment. The working condition pressure is required to reach 450bar. It is required to be delivered within 50 days. The quality needs to be comparable to that of HAWE in Germany. Just like Ningbo counterpart said, in Ningbo, there may not be a second manufacturer who is able to produce this high-pressure hydraulic needle valve except AAK hydraulic valve. Charlotte was curious about why the Ningbo counterparts recognized AAK high-pressure hydraulic needle valves so much, and AAK was also so confident in its own high-pressure hydraulic valves. What is the strength of AAK high-pressure hydraulic needle valves? Like horse racing, if you want to win the gold medal, then a good horse should be equipped with a good saddle and a good rider. What are the good horses, saddles and riders of AAK? If you need to meet the following 3 points at the same time, you may not be able to find a second hydraulic valve manufacturer in Ningbo to produce high-pressure hydraulic needle valves, except AAK hydraulic valve. 1. Good horses: AAK has high-precision machine tools imported from Switzerland, Mikron GF high-precision CNC machining center and GILDEMEISTER turn milling composite machining center. 2.
How do you understand mindfulness of be a man of credit and integrity to make hydraulic valves Today, a message on hydraulic valve website mindfulness of be a man of credit and integrity to do hydraulic valves. What does this mindfulness mean I checked the IP of this visitor deliberately because I'm not sure whether it's a hydraulic valve customer or a hydraulic valve peer, but I think it should be a foreign hydraulic valve manufacturer. Because of the differences of it is a little difficult to express it in English for the moment. Mindfulness is simply understood as which means praising a person's good character. But for the understanding of morality, everyone's standards are different. I consulted In the context of someone explained that which means intact. That is to say, a person who maintains consistency This marks a benchmark. What kind of person is Integrity It is a person who matches deeds to words, does what he says and is integrity. In hydraulic valves, take small things as example, I make an appointment and don't be late; Officially speaking, if you sign the hydraulic valve contract, you will abide by it; Take production as an example, the quality of each hydraulic valve is equal to or better than the confirmed parameters. hydraulic valves, combination of words and deeds. It dedicates itself to the production of hydraulic valves, never cheating with small actions. The ethereal thing of moral character becomes clear in hydraulic valves. I remember a few years ago, an hydraulic valve customer to visit hydraulic valve. may not be a big moral flaw, but it at least proves that such a person is not at least an integrity person, which conflicts with our hydraulic valve culture. hydraulic valve, mindfulness of be a man of credit and integrity to make hydraulic valves.
AAK hydraulic valve blocks are processed with compound cutting tools, and the production efficiency is nearly 50% higher than that of peers. At the same time, the precision of hydraulic valve blocks is also improved by 5%. AAK completed the urgent order of 1,000 hydraulic valve blocks in only 30 days, while most hydraulic valve block manufacturers can't control the processing technology of compound cutting tools. German customers are also attracted by it. It's a little strange that since the second half of last year, many inquiries about hydraulic valve blocks have an urgent delivery date. They need to be shipped within 20 days or finished within 30 days. For non-standard hydraulic valve blocks, from production drawing design, sample, life test, production to delivery, the vast majority of hydraulic valve block manufacturers need 45-60 days. But this is desperate for the customers with urgent order of hydraulic valve blocks, and Bach in Germany is one of them. Bach wanted to purchase 1,000 pcs of hydraulic valve blocks a few weeks ago. His customer requested that the goods be delivered to Germany in 50-60 days, but the quotation of the local factory in Germany exceeded his budget. He could only find the manufacturer of hydraulic valve blocks in Ningbo, that is, goods need to be shipped in 30 days. Bach contacted nearly 20 hydraulic valve block manufacturers, but none of them can complete the production of 1,000 hydraulic valve blocks in 30 days. A few days ago, we received Bach's message on AAK website (www.aakindustry.com): I saw an article on B2B that "AAK processes hydraulic valve blocks with compound cutting tools, and the delivery time is 30 days faster than peers". Can AAK complete non-standard hydraulic valve blocks in 30 days? After communication, I learned that Bach was troubled by the delivery date of hydraulic valve blocks. I directly told him that the 30 days of lead time for 1,000pcs of hydraulic valve blocks is enough for AAK. AAK adopts the compound cutting tool processing technology that most hydraulic valve block manufacturers can't control, that is, combining two or more similar or different types of hole processing tools into a special composite tool. In the process of machining, reduce the tools required for machining X, Y, V and U partial views, and complete the process combination of multiple processes such as drilling, reaming, spot facing and boring. At the same time, one tool can simultaneously process threaded bottom holes, 45 �°, 15 �°, R0.1 chamfering and external counterbore, which greatly improve the processing efficiency and have the characteristics of high efficiency, high precision and high stability. This is the "trump card" of AAK to improve the production efficiency. The production efficiency is nearly 50% higher than that of its peers. At the same time, the precision of hydraulic valve blocks is also increased by 5%.
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,
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.
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
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. â??Zhiliangâ??, also known as â??Pinzhiâ??, 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 Buddhist 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.
At AAK monthly hydraulic valve summary meeting, my first requirement for hydraulic valve technicians and workshop directors in various posts is that the quality of hydraulic valves needs to be good, and must be good. At least, our hydraulic valves must be benchmarked with domestic first-line hydraulic brands. Benchmarking or surpassing the first-line brands of international hydraulic valves is our mission. Whoever messes up the job will lose his job. If a product with poor quality is "packaged" into a great product, the heart will be extremely distorted and uncomfortable, which will be condemned by God. Especially in manufacturing, this is life-threatening. I think the only customer-centered requirement for the production of hydraulic valves is quality. Within the scope of my manufacturing ability, to make the quality of hydraulic valves to the extreme that I can do is to really focus on customers, no any other rhetoric. I have another understanding of the quality of hydraulic valves, that is, not excessive, because excessive quality is also a waste. For example, if the market needs 90 points of hydraulic valve, you can achieve 95 points. If you have to do 99 points of hydraulic valves, this may be excessive. Now the internal involution of hydraulic valves is very strong. Most hydraulic valve manufacturers are thinking about how to reduce costs and prices, and finally compete with low prices. This is the routine of most small bosses. Everyone focuses on the crazy competition on the same track without thinking about how to make a high-end market with high quality in the positioning of high-quality hydraulic valves. I think this is the sadness of the hydraulic valve manufacturing industry. Because of the impact of the epidemic, most hydraulic valve manufacturers choose to tighten, even the cost of hydraulic valve technician training has been tightened, thinking that hundreds of thousands or millions will be saved. In fact, this is short-sighted. Once the epidemic is over, all markets will rebound explosively. AAK hydraulic valves adhere to the monthly quality meeting, technician training, quarterly R & D expenses and annual equipment upgrading expenses. I think this is wise and necessary. AAK hydraulic valve is to concentrate all elements and use the sharp knife of quality to be the first in subdividing the vertical field of hydraulic valves. It is not only the first, but also the only. This is my purpose of producing hydraulic valves. Hydraulic valve manufacturers must not focus on multitasking. Focus on only one may not quickly open the market quickly, not to mention focus on 2 or 3 tasks, which is a fatal mistake. AAK hydraulic valves, in terms of quality, should not only be the first, but also the only. You are welcome to have a small try. AAK HYDRAULIC VALVES (212) 2022-04-30

Petrov is an old purchaser of Hydrosila Group in Russia. He cooperates with AAK on some non-standard hydraulic pilot operated relief valves and often discusses some difficulties and complications of hydraulic pilot operated relief valves. In the second half of last year, they needed to purchase a hydraulic pilot operated relief valve to test an agricultural machinery equipment. Due to urgent time, Petrov purchased from a Russian hydraulic relief valve manufacturer, who delivered 30 hydraulic pilot operated relief valves in 30 days. During the test run, the hydraulic pilot operated relief valves screamed at about 1.5MPa before opening, as well as at the start and stop. Petrov contacted the manufacturer of the hydraulic relief valves, and the manufacturer replied that the non-standard customization was completely based on the drawings provided, and the dimensional accuracy also met the requirements. Their engineers independently tested the hydraulic relief valves and found that there was really no abnormality. The boss was dissatisfied with the one week of delay due to the test run and asked Petrov to repurchase the hydraulic pilot operated relief valves. Because the hydraulic relief valve problems encountered before were solved by AAK, Petrov emailed me again. AAK engineer preliminarily judged that there may be problems in the design of the hydraulic pilot operated relief valve according to his fault description, the drawings of the pilot operated relief valve, the working parameters of the hydraulic system of agricultural machinery, and the video of the test machine. Knowing that he still has one month of flexibility, AAK can modify the original design of the hydraulic pilot operated relief valve and send 12 samples within 30 days. Four weeks later, AAK sent 20 samples of hydraulic pilot operated relief valves, which were installed and debugged without screaming, and the hydraulic power unit was started or closed for many times still without screaming. Petrov was surprised that AAK engineer found and solved the problem of hydraulic relief valveS at one time, while the original Russian hydraulic relief valve manufacturer can do nothing? Because the scream of pilot operated relief valve is often generated by high-pressure oil through damping hole or valve port, AAK engineer added inclined hole of valve seat and vibration elimination cavity in the original design. In this way, the dynamic and static characteristics of the hydraulic pilot operated relief valve can be improved, the screaming can be eliminated, the noise can be reduced, and the pressure control accuracy can be improved at the same time. AAK strong engineering team not only has the concept of German HAWE, but also has the experience of Italian Oil Controlï¼?the problem can be found at one time. After the successful test run, Petrov privately told us that the boss was very satisfied that he found a
Zero from Italy often purchases hydraulic valve blocks. In previous years, his customer gave 95 days for delivery date. Some time ago, the customer had an urgent order for 1,200pcs of hydraulic valve blocks, and there was only 60 days from the sample of hydraulic valve blocks to delivery. For non-standard hydraulic valve blocks, the lead time is less than 30 days from drawing design, sample, service life test, production and delivery. Zero consulted all hydraulic valve block manufacturers in cooperation. They all said that it would take 60 days to complete the urgent order of 1,200 hydraulic valve blocks only for production, and the lead time in 90 days is necessary. Zero can't refuse the customer directly, so he has to find a new manufacturer of hydraulic valve blocks. Zero also understands that it is not easy to find a reliable manufacturer of hydraulic valve blocks. Moreover, this is an urgent order, and the processing of hydraulic valve blocks is also complex. There was no reply from all the manufacturers he contacted on the Internet. Occasionally, he mentioned this urgent order of hydraulic valve blocks with his friend Caled. Caled introduced him to try AAK hydraulic valves. Caled is a customer that I have worked with for several years on integrated valve blocks. Caled told Zero that AAK helped him solve several urgent orders for manifolds, and the quality was guaranteed. Zero said frankly that he was introduced by Caled and hoped to get our help. According to the drawing sent by zero, the hydraulic valve block has long and thin channels and complex oil circuit design, which is unbearable for general processing. AAK technical team first arranged the production procedure and calculated the daily output of hydraulic valve blocks. It would take 30 days to complete this urgent order. While Zero was pleased, he seemed a little worried about the quality of AAK hydraulic valve blocks. Three weeks later, their engineers tested AAK hydraulic valve block samples. The overall accuracy parameter of the hydraulic valve block is 5% higher than that of the original manufacturer, which proves what Caled has mentioned that AAK quality mentioned is guaranteed. After working overtime for 30 days, AAK successfully completed the urgent order of 1,200 hydraulic valve blocks for Zero, which is half less than the 60 days of lead time required by peers. Zero was surprised how AAK achieved it? AAK adopts the machining center of compound tools to combine two or more similar or different types of hole machining tools into one special tool. In the process of machining, reduce the tools required for machining X, Y, V and U partial views, and complete the process combination of multiple processes such as drilling, reaming, spot facing and boring. At the same time, one tool can simultaneously process threaded bottom holes, 45 , 15 , R0.1 chamfer and outer counter bore, which greatly
Kayden, from AH Garner company in the UK, has successfully purchased hydraulic valve blocks in Ningbo in recent years, and has cooperated with AAK on some high requirements hydraulic valve blocks for many years. He sent an email at the end of last year: I need AAKâ??s help. After communication, we learned that a new hydraulic equipment of their company was complained by customers about oil leakage in about 3 months. After inspection, their after-sales personnel found that when the equipment is switched with high-speed and high-frequency action under high pressure, the small O-ring of the cover plate of the hydraulic valve block is prone to oil leakage. The engineer asked Kayden to find the original supplier to replace the hydraulic valve blocks or cartridge valves. Unfortunately, Kayden purchased the hydraulic valve blocks and threaded cartridge valves from two factories. The manufacturer of the hydraulic valve blocks replied that the thread size accuracy of the cartridge valves did not meet the standard and caused oil leakage, while the cartridge valve manufacturer said that the accuracy of the hydraulic valve blocks did not meet the standard. The hydraulic valve blocks and cartridge valves have passed the inspection. How can there be a problem as soon as they are assembled on the equipment? Kayden suspected that the design of the hydraulic valve block was flawed, but the engineer thought the design drawing was in line with the principle. The customer didn't receive the solution, and complained to the boss, who asked Kayden to completely solve the oil leakage problem of the hydraulic valve blocks within 30 days. Now Kayden was stumped and didn't have a clue. I asked Kayden to send us the drawings of the hydraulic valve block and cartridge valve, and system principles. AAK engineers found no problems after analysis. Our engineer asked Kayden to provide the video after the equipment was started up. Combined with the system schematic diagram and equipment fault video, our engineer judged that the position of installing O-ring at the interface of hydraulic valve block and cartridge valve was inappropriate. If the position of the O-ring is lowered, and the cover plate O-ring is completely free of oil, install and fasten the cartridge valve cover plate, and produce the hydraulic valve block and cartridge valve in a same factory, the oil leakage problem of the hydraulic valve block may be solved completely. Kayden seems to have seen the dawn and asked AAK to make samples. After 25 days, AAK sent out the integrated hydraulic valve block sample. A few days ago, Kayden emailed us that it has been 3 months since the hydraulic valve block was replaced with AAK samples, the equipment works normally without oil leakage. Kayden told me that AH Garner engineer admired AAKâ??s strictness in details. It is so obvious, why didn't he find such an obvious problem?
