Product Application: Applied to the first groove of aluminum pistons in internal combustion engines, primarily used in diesel engine aluminum pistons, with aftermarket sales predominating. Features: 1. Integration of Wear-Resistant Insert Rings with Internal Cooling Channels through brackets offers several advantages over pistons simultaneously using insert rings and salt cores: (1) Single positioning reduces operational and process difficulties and CT time, improving production efficiency. (2) Before casting, simple shot blasting and preheating of wear-resistant insert rings are sufficient, eliminating the need for separate treatment (3) Reduces quality loss caused by using salt cores, enhancing piston yield.(4) Decreases flushing procedures and costs associated with salt cores. (5) Minimizes wastewater handling and management. 2. Customized Design: Tailored design of bracket-type internal cooling channel wear-resistant insert rings to meet diverse piston and industry requirements, ensuring optimal adaptability. 3. Material: The wear-resistant insert rings are made of high-nickel austenitic cast iron, while aluminum pistons are typically made of silicon-aluminum alloy. Their similar coefficients of expansion form the basis for the application of wear-resistant insert rings in the first groove of pistons. Wear Resistance: High-nickel austenitic cast iron exhibits outstanding wear resistance, optimizing friction with piston rings at high temperatures, thereby increasing piston lifespan. Thermal Conductivity: The material boasts excellent thermal conductivity, facilitating heat transfer and dissipation to maintain piston head temperature within a reasonable range. Corrosion Resistance: Strong corrosion resistance enables adaptation to various working environments, ensuring stability under different conditions. Environmental Friendliness: Prolonging piston lifespan ensures combustion chamber sealing during piston operation, enhancing combustion efficiency, and reducing exhaust emissions. Precision Machining: Precise machining techniques during manufacturing ensure products meet design requirements, enhancing performance.
Product Application: Used in the first groove of aluminum pistons in internal combustion engines, initially applied to diesel engine aluminum pistons, with wear-resistant insert rings widely used and promoted on gasoline engine aluminum pistons in recent years as industry demands for gasoline engine pistons have increased. Features: Compared to traditional aluminum pistons, pistons with insert rings have seen an average increase in lifespan of 5-8 times, enhancing energy utilization and combustion efficiency, while reducing emissions. Additionally, it significantly improves the performance and reliability of internal combustion engines.

Product Application: Salt cores, when flushed out of the piston, form internal cooling passages, reducing the temperature of the piston head and the first ring groove area, thus enhancing the piston's lifespan. Features: 1. High Strength, Excellent High-Temperature Resistance: Salt cores do not fracture when preheated in a 720�°C furnace or during piston casting operations. 2. Immersion Resistance: Salt cores do not rupture or generate gas when poured with aluminum solution, nor do they cause salt to float on the solution's surface. 3. Easy Dissolution, Quick Flushing: After casting into the piston blank, salt cores can be completely flushed out within a maximum of 10 seconds under a water pressure of 200 bar. 4. Surface Quality: Salt cores exhibit no quality defects on the surface, such as cracks, sharp edges, burrs, notches, oil stains, etc., with smooth arc transitions. In modern internal combustion engines, pistons inevitably bear increasing thermal loads. Particularly with the increasing use of turbocharged engines in mid-to-high-end vehicles worldwide, turbocharging technology has become popular to enhance engine power and torque, improve fuel economy, reduce exhaust emissions, and lower fuel consumption. To meet the growing power requirements and ensure the safety of piston operation, pistons with internal cooling passages, formed by salt cores during the aluminum piston casting process and then removed by water flushing after casting, have become the inevitable choice for high-speed, high-power engines.
