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.
