PRODUCT DESCRIPTION Long lasting car radiator round aluminum tube 3103 anti-corrosion aluminum Φ12mm Product description: 3003 and 3103 anti-corrosion aluminum are used to produce automobile water tank pipes, which are products with high reliability, excellent performance and long-lasting durability. Its raw material is made of high-quality remelted aluminum rods, which are high-quality materials that have been strictly selected and tested to ensure the stability and durability of the product. In the production process, large-tonnage extruders are used. This advanced equipment can ensure that the raw materials are fully mixed during the extrusion process and have consistent chemical composition and physical properties. During the extrusion process, a large extrusion ratio extrusion technology is used, which allows the aluminum rod to gradually deform under pressure and form an aluminum tube of the required shape and size. This process not only gives the aluminum pipe excellent strength and corrosion resistance, but also makes the pipe wall thinner and lighter, thereby improving production efficiency and reducing production costs. In addition, the strength and corrosion resistance of aluminum pipes can be further enhanced through production processes such as hot extrusion and cold drawing. This process involves heating the aluminum tube to a certain temperature before extruding it, then rapidly cooling it and stretching it to form the desired shape and size. This process can make the internal lattice structure of the aluminum tube tighter, improving its mechanical properties and service life. Our company specializes in the production of various sized aluminum straight tubes with precise diameters and straightness to meet the needs of a variety of different applications. At the same time, they are also able to provide various specifications of MY 2M state aluminum tubes. These aluminum tubes have been specially treated and have good fatigue resistance and corrosion resistance, and are suitable for various complex application scenarios. Whether it is the production needs of rear tank expansion openings or expansion pipes, they can provide high-quality products that meet the requirements. Features: Automotive cooling systems play a vital role in the modern automotive industry. The main function of this system is to timely disperse the heat energy absorbed by the engine components, making the engine run more stable and efficient. Compared with traditional cooling systems, radiators using 3103 aluminum round tubes make the automotive cooling system lightweight, efficient, and compact, and are far ahead in terms of quality and performance. The advantages of automotive cooling systems with the support of 3103 aluminum round tubes are reflected in their excellent quality and excellent thermal conductivity. In addition, high-quality aluminum round pipes also have excellent corrosion resistance and can resist corrosion in harsh environments. The characteristics of being lightweight and easy to bend and form make 3103 aluminum round pipes widely used in many fields such as air conditioning ducts and heat exchangers. Taken together, the 3103 aluminum round tubes produced by our company not only have excellent heat dissipation performance, but also have high precision and low leakage rate. Its fast heat dissipation allows the cooling system to quickly dissipate the heat absorbed by the engine, ensuring that the engine can operate stably under various working conditions.

Chapman comes from a hydraulic equipment manufacturing company in Italy. He has been in the company for 3 years and is highly regarded by his boss. However, the hydraulic pilot relief valves purchased at the beginning of the year has been in a big trouble, which makes his boss more and more disappointed with him. They sold a batch of hydraulic power units, and there was squeal or vibration. They judged that it was caused by the abnormality of the hydraulic pilot relief valve. However, when they tested the hydraulic pilot relief valve separately, the parameters met the standard, and no abnormality was found. In a week, Chapman contacted different hydraulic valve manufacturers online and offline, but it was fruitless. The original manufacturer of the hydraulic pilot relief valve could not provide constructive suggestions. The boss is urging the after-sales plan. Chapman has not found the root cause of the equipment howling yet and has a big headache. Chapman tried to source Chinese hydraulic valve manufacturers on Google. He was surprised that AAK's natural ranking in Google actually ranked on the home page. He left a message to ask if AAK could solve the squeal of the hydraulic pilot operated relief valve. I didn't answer yes or no, but only sent him two links about the squeal solution of the hydraulic valves. AAK has solved the squeal of the hydraulic relief valves for 2 customers. 10 minutes later, Chapman sent the drawings of the hydraulic pilot operated relief valve and the product pictures of the original manufacturer. Our engineer asked him to separate the hydraulic relief valve into two halves along the axis of symmetry, with partial drawing pictures. The next day, I told him that it was not difficult to stop whistling, it is better to make samples directly. After 50 days, AAK sent 40 samples of hydraulic pilot operated relief valves for him to replace the ones on the equipment complained by customers. Last week, Chapman sent a PO for 360 hydraulic pilot operated relief valves, and told that it had been 6 months since AAK hydraulic pilot operated relief valves have been used on the equipment. There was no customer complaint about squeal or vibration, and the customer was satisfied. His boss asked him to replace all the original hydraulic pilot operated relief valves and only choose AAK. Different hydraulic relief valves have different causes of squeal, it needs a case by case analysis. Our engineer found that the dynamic performance of this hydraulic relief valve was not very smooth, so he set dynamic damping in its valve spool cavity. This damping and spring cavity constitute a first-order inertial link. The turning frequency is higher than the natural frequency of the second-order oscillating link of the valve spool, which can form an inter stage dynamic pressure feedback, improve the dynamic process, and effectively reduce the vibration of the dynamic process. The greater the vibration, the stronger the damping effect. AAK hydraulic pilot operated cartridge relief valve, no squeal, no vibration, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pilot-operated-relief-valves- aak38 , 3

Yesterday when I arrived at the workshop, a colleague said that engineer Mr. Li had undergone significant changes, which surprised and comforted me. 2 years ago, China hydraulic solenoid valve manufacturer AAK wanted to hire a full-time hydraulic solenoid valve engineer. During the interview, Mr. Li answered the questions about the knowledge of hydraulic solenoid valves professionally, but showed a dull performance in other aspects. After hesitating for a day, I still hired him because his expertise in hydraulic solenoid valves conquered me. After a three-month probationary period, the chief engineer of AAK, the China hydraulic solenoid valve manufacturer, did not recommend hiring Mr.Li because it is difficult to get along and communicate with Mr.Li, but I still signed a work contract with Mr.Li. My philosophy: When choosing people, you should choose people with shortcomings, and never choose perfect people. What kind of person is perfect? Communicating with him seems impeccable, and then we can't see any shortcomings. At the same time, his strengths are not particularly obvious. Perhaps most China hydraulic solenoid valve manufacturers, when looking for experienced people in their daily lives, would choose such a person. But what I want to say is that after selecting such a talent, basically he cannot achieve performance that exceeds your expectations. Generally speaking, a particularly outstanding talent is often particularly strong in one aspect, while also being particularly weak in another direction. Our engineer Mr.Li has a particularly strong technical ability in hydraulic solenoid valves. But his interpersonal skills are really weak and he is not very talkative. In those projects that need technical teams to assist each other, there are often some other colleagues offended by him, and he just has a thick skull in interpersonal relationship management. The chief engineer of AAK, a China hydraulic solenoid valve manufacturer, has complained to me multiple times. In the first time, I said, 'Let's treat Mr. Li as a child. We don't need to argue with children.'. In the last time, I patiently said to the chief engineer, “do you think the ability to handle interpersonal relationships is more important for Mr. Li's position, or is his professional and technical skills more important?” The chief engineer of AAK, the China hydraulic solenoid valve manufacturer, said that of course, it is the professional technical ability. I said to the chief engineer of AAK, a Chinese hydraulic solenoid valve manufacturer, “why don't you use his professional technical skills as an engineer but want him to be a person who is particularly skilled in handling interpersonal relationships? As the technical leader of AAK, a China hydraulic solenoid valve manufacturer, aren't you the one who makes up for his shortcomings?” The chief engineer of China hydraulic solenoid valve manufacturer AAK seems to have awakened, starting to create opportunities for Mr. Li, how can he improve Mr.Li’s relationship with other members? In the hydraulic solenoid valve project meeting, let Mr. Li talk about his past experience first, so that others can better understand his way of thinking. Then, talk the specific views of the chief engineer about the project, so that everyone can understand Mr.Li’s logic. Mr.Li’s changes have been significant. I was surprised by his growth and pleased with the progress of the team. There is no perfect individual, only a perfect team. China hydraulic solenoid valve manufacturer AAK, selects talents with shortcomings.

Pancrazio is from a hydraulic equipment company in Italy. In recent years, his purchase of hydraulic valves in China has been smooth. Recently, he was trapped by a 450bar high pressure hydraulic cartridge relief valve. At the beginning of last year, their new hydraulic power unit was complained by customers about unstable pressure supply 6 months after it was sold. During after sales checking, it was found that the hydraulic cartridge relief valve spool was not flexible. The original manufacturer of the hydraulic cartridge relief valve advised that under 450bar high pressure frequency use, the valve cage was deformed, then the valve spool was not flexible, the only solution is to replace the valves with new ones. Later, with more and more complaints, Pancrazio realized that the service life of the hydraulic cartridge relief valves produced by the original manufacturer was only 6-9 months. Such frequent replacement is not affordable, they must find a new hydraulic valve manufacturer, the service life of the hydraulic cartridge relief valve must be more than 24 months. Pancrazio contacted more than 10 manufacturers, but none of them was able to guarantee that the service life of the hydraulic cartridge relief valve under 450bar high pressure, can be 2 years. 2 weeks passed, but no progress. Pancrazio became panicky. Pancrazio saw in Google that AAK released a series of 450bar pressure resistant hydraulic cartridge valves and left a message asking: How long is the service life of AAK's 450bar pressure resistant hydraulic cartridge relief valve? There are similar messages every day. I only answered "The price of AAK hydraulic cartridge relief valve is 20% higher, but its service life is twice that of the peers". In the afternoon of the same day, I received the drawings of the hydraulic cartridge relief valve and the pictures of the original manufacturer's hydraulic cartridge relief valves from Pancrazio. He emphasized the requirements of the 450bar pressure resistance and the service life of 2 years. Our engineer is a little surprised that the original manufacturer's hydraulic relief valves will be abnormal in 6 months. After a careful look at the design of the original hydraulic cartridge relief valve, we had an idea and suggested making samples directly. Although Pancrazio was some hesitant, there was no better choice. After 45 days, AAK sent 50 hydraulic cartridge relief valves to replace the ones on those abnormal equipments. Last week, Pancrazio emailed us that AAK hydraulic cartridge relief valves have been installed in the equipment for 1 year, there was any complaint about unstable pressure supply. Their engineers realized that AAK had directly modified the design of the original hydraulic cartridge relief valve, and they admired our minds. I told him that if there was no accident, in 24 months, there would be no repair report for AAK hydraulic cartridge relief valve and no complaint from the customers. This hydraulic cartridge relief valve, hydraulic system and working conditions are a little special. The original hydraulic cartridge relief valve is designed to be composed of a valve cover, a valve cage and a valve spool. Most hydraulic valve manufacturers mainly focus on standard parts and can only produce according to drawings, without system knowledge of hydraulic valves. We operate like this, which is the 3 points admired by their engineers. 1. We open a large round hole in the center of the upper part of the valve cover, and the valve spool reaches the valve cage through the large round hole and is installed in the inner cavity of the valve cage. This is the change of the appearance. 2. Enlarge the valve spool diameter and valve cage inner diameter in the same proportion, increase the valve spool stroke, increase the oil flow, and make the system oil more stable, which is helpful to the performance. 3. The area around the oil outlet of the valve cage is designed to be convex, and the high-pressure oil flows out through the outlet of the valve cage, which has a buffer, which is more resistant to high pressure and has better performance. The price of AAK hydraulic cartridge relief valve is 20% more expensive, but its service life is twice that of its peers. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-relief-valves- aak382

The original manufacturer of the hydraulic manifold block made samples for 3 times, pushed the delivery for 3 times, but the samples were still not approved. There was always 0.5~1.0mm burrs in the deep hole of the hydraulic manifold block. After AAK took over, in terms of process, it abandoned the conventional route, optimized 3 points, and got the samples approved at one time.   Tom from Holland, their customer wanted to develop a hydraulic manifold block. The maximum side length of the hydraulic manifold block is 800mm, including multiple 4 × M8 threaded holes and Φ 14、 Φ 17 deep holes, and the accuracy is more than 10% higher than the conventional one. Tom knew the difficulty of this hydraulic manifold block and the importance of this customer, so he selected 2 most recognized hydraulic manifold blocks manufacturers to make samples at the same time. It took 8 weeks to sample 3 times, and there were still 0.5~1.0mm burrs in the deep holes of the hydraulic manifold blocks. The customer was not satisfied. If the next sample of the hydraulic manifold block still can not be approved, the order had to be cancelled. Within 2 days, Tom contacted more than 30 hydraulic manifold block manufacturers, and those old suppliers suggested him giving up, which made Tom very anxious.   Tom found AAK website on B2B and noticed AAK has tricks on the processing and deburring of hydraulic manifold blocks. With the attitude of trying, he contacted us. When receiving the drawing of hydraulic manifold block sent by Tom, AAK technical team was also a little surprised. The hydraulic manifold block is large size but with long and thin holes, and most of the holes are Φ 14、 Φ 17. The depth is more than 400mm, most of which are deep holes with a length diameter ratio greater than 28. This is a challenge for machining, especially for deep hole machining. The tool is long, chip removal is difficult, chip extrusion is easy, and the drill bit is easy to break, with many potential burrs. 2 days later, AAK technical team had a commencement plan. I replied to Tom by email that AAK was willing to develop this hydraulic manifold block and is 90% confident to be successful.   After 30 days, we sent 5 hydraulic manifold blocks. 2 weeks later, Tom emailed us that the customer had approved AAK hydraulic manifold blocks, which not only met the accuracy standard, but also completely removed the burrs. For the deep hole processing of this hydraulic manifold block, the other hydraulic manifold block manufacturers can not meet the precision and remove burrs completely, maybe they still use traditional technology. AAK has always adhered to process innovation and technology optimization. Aiming at the characteristics of this hydraulic manifold block, AAK has made adjustment and optimization from 3 aspects:   1. Most hydraulic manifold block manufacturers use machine tools and gun drills to process deep holes. The deviation of this hydraulic manifold block hole reaches 1/800. AAK selects a machining center and adopts the two end butt joint processing technology. First, use an alloy milling cutter to process a certain depth of the guide hole, and then use a short to long fried dough twist drill to process the deep hole, and strictly control the deviation error range of the hole.   2. Adjust the traditional cutting speed, feed rate, cutting rate and other parameters. AAK adopts the cutting speed of 160m/min, feed rate of 0.25mm/r, and cutting rate of 0.5~2.0mm, which improves the cutting direction of burrs, avoids 0.5~1.0mm additional burrs occurred during processing.   3. Before assembly, use kerosene circulation and ultrasonic cleaner to wash the hydraulic manifold block for more than 1h, remove dirt, chips, fine burrs etc. on the hole wall, and then inspect with the endoscope.   AAK hydraulic manifold block, processing does not produce extra burrs, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak438

For the processing of the main valve hole of the hydraulic cartridge relief valves, AAK uses a new 4-step method instead of the traditional 4-step method, which is 100% burr free. Rubio from Mexico, placed the big order 1 week after the first test order. Regarding the burrs in the main valve hole of the hydraulic cartridge relief valves, it involves 2 parts: how to effectively avoid and remove them. How to effectively avoid is the root cause. How to remove is the symptoms. AAK focuses on the root cause, while other hydraulic valve manufacturers pay attention to the symptoms. Burr is common in machining. As for how to control the burr in the main valve hole of hydraulic cartridge relief valve, most hydraulic relief valve manufacturers ignore the dead corner in the undercut groove. No matter how to clean it, the pain point of "black under the light" cannot be solved. 2 years ago, Rubio purchased the hydraulic cartridge relief valves from China for the first time, and almost overturned. For a hydraulic cartridge relief valve with a rated pressure of more than 30MPa, and a clearance of 0.006 ~ 0.01mm between the valve body and the valve spool, samples were made by 4 hydraulic valve manufacturers successively in 8 weeks. The parameters of each sample of the hydraulic cartridge relief valve were qualified during independent testing. However, once it was installed on the equipment and tested, the hydraulic system would not function very well. The root cause is the burr residue in the dead corner of the hydraulic cartridge relief valve cutting groove. Rubio browsed a series of articles about the burrs of AAK hydraulic valves and hydraulic valve blocks on the B2B website. When Rubio learned that HydraForce, SUN Hydraulics, are also loyal customers of AAK for more than 5 years, he seemed to be in no worry. According to the technical parameters provided by Rubio, we have existing procedure for this hydraulic cartridge relief valve. We sent 5 samples of hydraulic cartridge relief valves the next day. For the machining of the main valve hole of the hydraulic cartridge relief valve, AAK uses a new 4-step method instead of the traditional 4-step method, which is 100% burr free. 1 week after Rubio received our test samples, he sent the PO of 600 hydraulic cartridge relief valves. The undercut of the main valve hole of the hydraulic cartridge relief valve is the place where the most burrs are generated. The traditional processing route is: first rough boring, then semi fine boring, then milling the undercut, and finally reaming. After reaming, the burrs generated are in the same direction with the axis line of the hole, and sink into the undercut, forming the burr residues in the dead corners of the undercut, which cannot be 100% removed. We do not ignore this pain point. After several rounds of technical reform, we optimized a new 4 step method: first rough boring, then semi fine boring, then reaming, and finally milling the groove. The burr found after processing is perpendicular to the axis line. The burr here is visible and can be removed, and it is easy to remove without leaving dead corners.
