Binzhou Zhengdao Mechanical Manufacturing Co., Ltd.

Product Usage:
The first ring groove applied to the aluminum piston of the internal combustion engine, the first applied to the aluminum piston of the diesel engine, with the improvement of the industry's requirements for the piston of the gasoline engine in recent years, the wear-resistant inlay ring has been widely used and promoted on the aluminum piston of the gasoline engine in the past ten years.
Peculiarity:
Compared with traditional aluminum pistons, the service life of pistons with rings is increased by an average of 5-8 times, which improves energy efficiency and combustion efficiency, and reduces emissions. At the same time, the performance and reliability of the internal combustion engine are greatly improved.
Material: The material of the wear-resistant ring is high-nickel austenitic cast iron, and the aluminum piston is usually a silicon-aluminum alloy, and the expansion coefficient of the two is similar, which is the basis for the wear-resistant ring ring to be applied to the first ring groove of the piston.
Abrasion resistance: High nickel austenitic cast iron has excellent wear resistance, and achieves the optimal friction negative with the piston ring in a high temperature environment, which improves the service life of the piston.
Thermal conductivity: The material has excellent thermal conductivity, which helps to transfer and dissipate heat, ensuring that the piston head temperature is in a reasonable range.
Corrosion resistance: strong corrosion resistance, adapt to different working environments, and ensure stability under various conditions.
Environmental protection: It prolongs the service life of the piston, ensures the tightness of the combustion chamber when the piston does work, improves the combustion efficiency and reduces the exhaust gas emission.
Precision machining: Precision machining technology is used in the manufacturing process to ensure that the product meets the design requirements and improves performance.
