Our product is made of 2618 forged aluminum alloy, with a tensile strength of 450MPa, which is 60% stronger than ordinary cast pistons and can better cope with high temperature and high pressure working conditions of engines.
Our product has undergone five axis CNC precision machining, with dimensional tolerances controlled within ± 0.002mm, ensuring precise fit with the cylinder wall and reducing the risk of air leakage.
Equipped with low tension piston rings, the friction coefficient is reduced by 30%, reducing power loss, while improving sealing and reducing oil consumption.
Each piston undergoes multiple quality inspection processes such as size testing, pressure testing, and wear resistance testing to ensure reliable quality.
