We use advanced technology to cut out a seal groove in the middle of ball middle of ball milled founder iron piston ring. After all kinds of rub-resistant alloy materials being inlayed in the seal groove of piston ring*the rub-resistant alloy seamlessly integrates with the piston ring as a whole. As a result of the qualities of high rub resistance and good oil stockpile, the coefficient of friction has been greatly reduced. Simultaneously, the lubrication and steeling functions both are improved significantly, which making the piston rings never worn off, and the engine remains strong explosive force. This technology takes advantage of a new national patent.

The use of advanced nano-permeability ceramic equipment and ultra-low-temperature plasma particles vapor deposition generates one metal infiltration of ceramic layer on the surface of piston rings on which two-phase diffusion and network structure coexists. So that the surface hardness of piston ring increases by 20% and the corrosion resistance is significantly reduced. PERFORMANCE: Withstanding ultra-high temperature: The thermal conductivity increases by 45%, and increases with temperature.
