Is the working environment of piston ring demanding?
The working conditions of the piston ring are quite harsh, which requires not only high temperature and high pressure, but also severe wear and large impact load, thus putting forward extremely high requirements for the materials of the piston ring. In order to meet the needs of the whole machine, the company has invested a lot of manpower and material resources in material production and development, and achieved certain results. At present, the company has established a series of piston ring materials from medium and low grade to high grade, with complete specifications of various materials to meet the needs of various models at home and abroad. In the production and development of materials, the company has fully adopted the advanced standards of international peers, introduced and digested the casting technology of Gertz company and the world's advanced smelting and molding equipment, and developed and produced medium and high-grade piston ring materials, among them, 'high-speed engine ductile iron piston ring' and 'high-strength, high wear-resistant piston ring' materials won the title of national new product. In the process of material production and development, the company uses the double power supply frequency conversion electric furnace of Yingda company in the United States to smelt molten iron. Advanced testing and control equipment at home and abroad to ensure that the company's piston ring materials achieve first-class quality. For example, in the furnace front control, the direct reading spectrometer of BAIDAS company in the United States is used to control the chemical composition of molten iron, and the spectrometer uses different metal elements to generate different spectra, to quickly and accurately analyze the chemical composition of the sample to ensure that the chemical composition of the material meets the specified requirements; The EMIA820O infrared carbon and sulfur meter of Japan's HORIBA company is used to accurately analyze two extremely important elements C and S in piston ring materials. The instrument uses infrared absorption principle to measure the contents of C and S at the same time, the measurement accuracy range can reach 0. 0001% ~ 6. 0000%, and through the computer for data processing, display, printing, so that the analysis is correct, fast, convenient; The image analyzer produced by LEICA company in Germany is used for image analysis. The analyzer can observe the physical object and metallographic structure. Picture Display, image photographing, and the length, area and phase ratio of metallographic structure can be analyzed and printed by Q600 system software, thus greatly improving the metallographic analysis capability of the company, the application of these detection and control equipment ensures the medium and high grade and serialization of piston ring materials produced and developed by the company, and stabilizes the casting quality of the company for a long time. In terms of heat treatment, the company uses UNICASE drip type gas carburizing and nitriding furnace automatic line produced by Sino-Japanese cooperation to heat treat nodular cast iron piston rings, and uses well tempering furnace to age treat piston rings, the application of this heat treatment technology in China is relatively mature. Generally speaking, the company is close to the international level in the production and development of medium and high-grade materials.

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 high end piston ring solutions.
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.
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.
