With the high precision processing equipmentsand measuring instruments from Japan and Switzerland, the quality and properties of our piston rings are stable and reliable. New technical processing such as Ti-plating, molybdenum spraying, diffusion ceramic and plasma nitride can be applied to the rings. Ring diameters range from 27 mm to 170 mm. The rings are available for gasoline, diesel and hydraulics engines. Over 300 piston rings have been developed. |
