9 months ago, we received an email from an old customer in the UK, informing that Berge had transferred from the quality control department to the import department. We could see from the email of the young man's self-introduction that he was full of confidence in procurement. Unfortunately, the first hydraulic valve order went wrong. A batch of orders for hydraulic flow valves shipped from a hydraulic valve manufacturer in Ningbo had no problem when tested before leaving the factory. However, when the goods were delivered to customers, the company received a series of quality complaints from consumers in only 1 month, and nearly 20% of the hydraulic flow valves had leakage. The boss was not very happy, and requested Berge to solve the guest's complaints within 1 week. Berge had discussed with the original hydraulic valve manufacturer several times, but it has not been effectively solved, and he even wanted to resign. Shawn, a former old purchaser, felt his frustration and reminded him to communicate with AAK HYDRAULIC VALVE to see if it could be solved. We received Berge's email with product drawings, pictures and test data of the defective hydraulic flow valves. We preliminarily judged that there was a problem with the valve spool. In order to solve the problem at one time, Berge asked his hydraulic valve manufacturer to send 5 samples of defective hydraulic flow valves to AAK HYDRAULIC VALVE for thorough inspection. After receiving the hydraulic flow valve samples, frankly speaking, the main line type of the hydraulic flow valve was acceptable. The problem was that the valve spool deviated from the central axis, resulting in leakage. Of the 5 hydraulic flow valve samples sent, two were in this situation, and the other three were of acceptable quality. This proved what we said before that it was difficult to 100% ensure that the valve spool did not deviate from the central axis due to human error, which was a hidden problem among peers. I suggested him to replenish 40% hydraulic flow valves to their customer within 30 days. If the customer could accept this suggestion, we would give priority to the production of these replenished hydraulic flow valves. A week later, Berge informed by email that his boss had agreed to the plan and his customer could accept only 20% replenishment. They just repeatedly stressed that the replenishment of the hydraulic flow valve could not have any quality problems. AAK realized a few years ago that the hydraulic flow valve produced by CNC lathe has high requirements for operators and is prone to human errors, resulting in the deviation of valve spool from the central axis. On the production equipment, AAK HYDRAULIC VALVE have imported the Swiss machine tool with the highest precision to make up for the short board of CNC lathe. At present, less than 10% of the peers have this equipment. It can replace 7 groups of accessories at random. The high-pressure hydraulic flow valve produced by Swiss equipment has high precision, which is at least 20% higher than that of domestic conventional CNC lathe. Not only the precision is high, but also the stability is guaranteed. Last week, we received Berge's good news email. The customer was very satisfied with the replenishment of the hydraulic flow valve, and the boss was also very happy. Berge also joked with us that it was thanks to us AAK HYDRAULIC VALVE, otherwise he would have changed his job. AAK hydraulic flow valve, our old customers have been purchasing because of trust. You can also have a try. https://www.aakindustry.com/info-detai , l/hydraulic-flow-valve-aak99

Blade is from Canada. He has been purchasing hydraulic components successfully for 3 years. Unexpectedly, a hydraulic cartridge directional control valve stumped him. In the second half of last year, a batch of their hydraulic logistics lifts were complained by customers, some of them were unable to work, probably because the hydraulic cartridge directional control valve leaked. After checking, it was found that the valve spool was deformed. The original manufacturer of the hydraulic cartridge directional control valves said that it had been shipped for 9 months, and some exceptions were inevitable. It is possible that the internal stress of the valve spool was not eliminated in time during the heat treatment process, resulting in deformation or cracking of the valve spool. However, there are more and more complaints later. Blade realized that the service life of the hydraulic cartridge directional control valves from the original cartridge valve manufacturer may be about 1 year. He had to find a new hydraulic cartridge directional control valve manufacturer with a service life of 2 years. A week has passed, and no one can guarantee a 2-year life span. Blade found AAK when browsing Google. He noticed that AAK was continuously supplying HydraForce, and left a message: Can AAK ensure that each hydraulic cartridge directional control valve spool is free of deformation or cracking within 2 years? I guess he encountered trouble in purchasing hydraulic cartridge directional control valves. After communication, I learned the above information. I replied that the life expectancy of 2 years should not be a big problem. Blade sent the drawing of the hydraulic cartridge directional control valve and asked for the lead time for 10 samples. After 45 days, AAK sent the samples of the hydraulic cartridge directional control valves, but there was no email from him after that. Last week, Blade suddenly sent an email, and it was a PO for 600 hydraulic cartridge directional control valves. It can be seen that the samples of AAK hydraulic cartridge directional control valve was approved by his customer. The valve spool is the key to long service life of this hydraulic cartridge directional control valve. 1. AAK select 20CrMo material to produce the valve spool. After quenching and tempering, the materials are more conducive to processing. Most hydraulic cartridge valve manufacturers ignore this action. 2. 0.25~0.35mm machining allowance shall be reserved for rough turning, then carburizing, quenching and high temperature tempering shall be carried out, and then the valve spool shall be subject to low temperature cold treatment. The surface hardness of such valve spool is above HRC63, and the residual austenite in the internal structure is eliminated. 3. The valve spool shall be subject to semi finishing, and 0.1-0.15mm allowance shall be reserved during the process, and then the valve spool shall be subject to tempering treatment. The temperature of tempering treatment shall be 320°C, and the temperature shall be kept for 5 hours, which can eliminate the residual internal stress and greatly improve its stability. After tempering the valve spool, the honing machine shall be used for finishing to ensure the accuracy and ensure that each valve spool meets the standard. AAK hydraulic cartridge directional control valve, the valve spool is processed specially, you can also try a small order! https://www.aakindustry.com/info-det , ail/directional-control-valves-aak439

Beardsley is from Canada and has been working with hydraulic cartridge valve manufacturer AAK for 3 years, with an increasing number of inquiries every year. In early July this year, Beardsley asked me if there was a hydraulic cartridge flow control valve equivalent to HydraForce NV08-20? Can AAK complete the production of 300 pcs of hydraulic flow control valves in 20 days? It is the first time that I received such an urgent email from Beardsley, he was very calm in every purchase. After communication, I learned that their new colleague confirmed an order with a hydraulic cartridge valve manufacturer in Ningbo for 300 pcs of hydraulic flow control valves NV08-20. The hydraulic cartridge valve manufacturer promised a delivery time of 25 days, but 30 days have passed. However, the hydraulic cartridge valve manufacturer advised that it will take another 30 days because it is currently the peak production season for the hydraulic cartridge valve manufacturer. The new colleague is out of options and can only seek help from Beardsley. If without inventory and stock, to complete the production of 300 pcs of hydraulic flow control valves NV08-20 in 25 days is really difficult. Most hydraulic cartridge valve manufacturers in China just focus on domestic sales orders, and for export orders, these hydraulic cartridge valve manufacturers usually accept the orders first to fill the capacity gap. Once domestic sales orders arrive, they give priority to the domestic market orders. Beardsley is very aware of the current situation of hydraulic cartridge valve manufacturers in China, so he is very cautious when choosing hydraulic cartridge valve manufacturers, which is also the reason why he is sending AAK more and more inquiries. AAK has the program for hydraulic flow control valve NV08-20, confirmed the order for 300 pcs of hydraulic flow control valves with Beardsley the next day, and the production time is only 18 days. Beardsley asked about the reason for the fast delivery time, and I sent him a video of the machining of the hydraulic flow control valve cage first. The production of the valve cage is carried out by AAK using Japan's Mazak automatic CNC lathe, which does not require old technicians to ensure machining accuracy and the processing of the valve cage can be completed automatically. AAK has improved the feeding tray to a 30 degree angle, and the valve cage's material is arranged on the tray in a line, automatically entering the fixture of the lathe. After the system corrects the positioning, processing begins. After processing, the valve cage is automatically sent out. This kind of automated processing reduces the number of clamping times for technicians, which is more than 40% faster than most processing methods. AAK has been taking action to create hydraulic cartridge valve manufacturers for unmanned processes. Currently, hydraulic cartridge valve manufacturers who do not upgrade to unmanned equipment, may go to the end of their business in 5 years. What we can think of is the unmanned workshop of hydraulic cartridge valve manufacturers, which can minimize labor costs. The factory has fewer employees, greatly reduces management difficulty, and the key is to eliminate human error. I believe that the scale of future hydraulic cartridge valve manufacturers will no longer be measured by the number of workers, with a few or dozens of people. The key is the hydraulic cartridge valves produced in unmanned workshops, which have stable quality and low production costs. Who doesn't love them? I am now replying to Beardsley regarding the reason why AAK produces faster than other hydraulic cartridge valve manufacturers. 1. AAK uses equipment from the Japanese military industry, and I am not aware of the hydraulic cartridge valve manufacturers in Ningbo who have more efficient equipment than this. 2. The quality is equivalent to HydraForce and stable, and AAK is willing to purchase various raw materials in bulk. 3. Unmanned production workshop, with an efficiency 40% higher than most hydraulic cartridge valve manufacturers in China. Hydraulic cartridge valve manufacturer AAK, has 3 major guarantees for fast production, and you can also try it out!

Dicyandiamide, also known as dicyandiamide, cyanoguanidine, or DICY for short. The dicyandiamide curing agent is a typical latent curing agent for epoxy resin. A latent curing agent usually means that it can be stored stably at room temperature after being mixed with epoxy resin, but once it is heated, the curing reaction will be triggered by the action of light, moisture, or pressure to form a cured product. Dicyandiamide curing agent belongs to the latent curing agent of heating curing. It is solid at room temperature, insoluble in epoxy resin, and dispersed in epoxy resin in the form of fine particles. After heating reaction, once heated to the melting point, it begins to dissolve and react quickly to cure. Dicyandiamide micro-powder is dispersed in epoxy resin, which has a suitable storage period and stable storage. No delamination, no curing. The fineness of dicyandiamide particles in different products will be different, and the finer the dicyandiamide particles, the more obvious the performance advantage for curing reaction: Compared with ordinary dicyandiamide, ultrafine dicyandiamide particles are more easily dispersed in epoxy resin liquid.
