●  20 years of professional experience and accumulation in production of piston ring, We have received high recognition from many manufacture factories and the market.

●  Process Fine Indeed, high precision，single piston ring tolerance control is 0.004mm

●  Piston rings can sell more than 100 million pairs a year，minicar  large automobile  motorbike piston rings have always been good for sales.

●  Long service life； Piston rings can last up to a year on average，adaptability raises the ability to work better

●  High hardness; Cylindrical winding plated ——Hardness is above HV850

Cylindrical nitriding——Hardness is above HV1100

The nitrification is based on the colored coating——Theoretical hardness can reach HV2000~HV3000

●  Materials with high hardness and abrasion resistance

●  Reliably Sealing：opening gap and Flange kept it at10-25mm，in the state of high speed motion, the sealing effect between the crankcase is completed
