Piston rings act as core sealing components for all power machinery, undertaking gas sealing, oil scraping, heat dissipation and friction reduction. Different working temperature, cylinder pressure, rotation speed and load conditions demand differentiated surface coating technologies. Following international uniform testing standards, we independently develop and mass-produce four mature high-end piston ring coating solutions. Each process carries unique hardness, friction and durability parameters, targeted for distinct working scenarios. Improper coating selection will cause liner scratching, oil burning, gas leakage and premature ring failure.

Our Ceramic Titanium Piston Ring uses cutting-edge nano ceramic coating and multi-arc ion plating process. In a high vacuum environment, high-energy plasma reacts and deposits uniformly to form high-performance coatings like TiN, TiC, ZrN, ensuring strong bonding with the substrate.
It features ultra-strong adhesion and high compactness. Hardness reaches 2200–2500 HV, 3–12 times higher than raw materials, classified as a super-hard coating. With friction coefficient 0.4, wear resistance is improved by 150 times, providing outstanding durability under extreme working conditions. The high-density coating also delivers superior corrosion resistance and stable low-friction performance.
Designed for high-performance engines and heavy-duty machinery, our ceramic titanium piston rings combine advanced technology with strict quality control, fully embodying Precision Craftsmanship, Technological Leadership.

Our CKS (CID) Piston Ring adopts upgraded Chromium-based Composite Ceramic technology, an industry breakthrough that meets Euro IV emission standards and delivers double the wear resistance of conventional chrome plating.
The process forms uniform mesh textures inside the outer chrome layer, filled with wear resistant particles to enhance anti-friction performance. The mesh structure also provides excellent oil storage capacity, effectively lowering friction and protecting cylinder liners. The ring body is strengthened by nitriding treatment, boosting hardness, strength and impact resistance.
