High-End Product Introduction: DLC Piston Rings
Our high-performance DLC piston rings feature premium Diamond-Like Carbon (DLC) coating, crafted via advanced PVD technology. With ultra-low friction (0.01–0.2), exceptional hardness (65–80 GPa) and outstanding wear resistance, these low-friction DLC piston rings deliver reliable performance for even the most demanding engine applications. Backed by our rigorous in-house tests, our wear-resistant piston rings embody precision engineering and technological leadership, ensuring long-lasting efficiency and durability.
High-End Product Introduction: PVD Ion Plating Piston Ring

Our PVD Ion Plating Piston Ring is manufactured with advanced multi-arc ion plating technology under high vacuum conditions. Stable arc discharge between cathode and anode generates high-energy plasma, which deposits dense, uniform coatings such as TiN, CrN, ZrN onto the piston ring surface under workpiece bias voltage.

With excellent adhesion and high bonding strength, the coating stays firm without peeling. Hardness reaches 1800–2500 HV, 4–6 times higher than base materials, recognized as a super-hard coating. Friction coefficient is 0.4, delivering 10× improved wear resistance and outstanding corrosion resistance. Ideal for heavy-load engines, construction machinery and commercial vehicles, it greatly extends service life and reduces maintenance costs.

Backed by professional PVD coating equipment and strict quality control, Hearten Auto Parts upholds Precision Craftsmanship, Technological Leadership to provide reliable highend piston ring solutions.
High-End Product Introduction: Ceramic Titanium Piston Ring

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.
High-End Product Introduction: CKS (CID) Piston Ring

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 wearresistant 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.
Piston ring is broken what symptom phenomenon does leak have?
Piston ring is broken what symptom phenomenon does leak have?
The bad piston ring​ may be related to the air leakage caused by its wear or coke connection with the piston ring groove. If after cutting off a cylinder, the exhaust gas no longer from the oil or vent vent, the cylinder piston is not good use.
What is the  role of piston ring?
The piston ring is the core component of the fuel engine. It seals the fuel gas with the cylinder, piston, and cylinder wall. Piston ring functions include four functions: sealing, adjusting engine oil (oil control), heat conduction (heat transfer), and guide (support).
