| Message: | The local manufacturer who has cooperated for 5 years can't meet the precision requirements of the hydraulic cartridge pressure control valve spool, and the defective rate is up to 70%. They gave up 2 weeks after receiving the order. After AAK took over, 3 targeted processing skills were used. The roundness of the hydraulic cartridge pressure control valve spool accuracy could be less than 0.0005, the finish less than Ra0.02, and the percent of pass was more than 95%. Nabulung was completely relaxed after receiving AAK samples of hydraulic cartridge pressure control valves. |
