AAK Hydraulic Cartridge Directional Control Valve Deburring Skill

Tim comes from Mexico, and started purchasing hydraulic cartridge directional control valves from AAK 3 years ago, including customized ones and models benchmarking SUN or HydraForce. At the beginning of this year, Tim wanted AAK to lower the price of a hydraulic cartridge directional control valve equivalent to HydraForce. The reason was that he received quotations from other hydraulic cartridge manufacturers in China, which were 13% cheaper than AAK. I gave him a 3% discount, but Tim still chose a new hydraulic cartridge valve manufacturer. 3 months later, Tim came back to AAK. After communication, it was learned that he had encountered trouble with burrs in the hydraulic cartridge directional control valves produced by the new hydraulic cartridge valve manufacturer.
