Product Description

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.
