＊ The advantage of Completely-Automatic welding;
Veracity of installation position;
Reliability of welding intensity;
Stability of un-leakage.

＊ Unique gas-charge method by injecting the gas from the bottom, meanwhie, sealing it by projection welding. It can ensure the comsistency of gas pressure and no damage to the oil-seal lip.

＊ Teflon Piston-ring integrated with piston, not only reduce the friction and noise, but also avoid inner-leakage.

＊ Multiple-lip oil-seal,with Stable and reliable quality , keep it no oil-leakage and no friction.

＊ 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.

＊ Aduanced multiple-type bottom valve system structure, guarantee multiple damping forces realized and match the suspension system better.

＊ High-quality working liquid, ensure all-weather adaptability under different temperature conditions.

＊ Automatic paint surface-system lines, assure weatherproof under all different conditions and excellent appearance.
