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!
