1.Strictly according to IATF 16949 quality certification system process production；The advantages of automatic welding ensure the reliability of welding strength, no leakage stability, installation position accuracy；Teflon piston-ring integrated whith piston,not only reduce the friction and noise,also avoid inner-leakage；Unique gas-charge method by injecting the gas from the bottom,meanwhile,sealing it by projection welding.It can ensure the consistency of gas pressure and no damage to the oil-seal lip.；.Gas-filled shock absorber injected with pure N2,which not only keeps stability of damping force,but also reduce aerification and foaming,meanwhile,extend the effective life；Hard-chromed piston rod with micro-grooves,increasing the rigidity and reducing friction,keep better lubrication action.
