Low pressure casting aluminum alloy flywheel shell, as a key component of the power transmission system, adopts low pressure casting process combined with high-quality aluminum alloy material, which is both lightweight and high-strength. Its precise structural design can effectively carry the flywheel and isolate it from external impacts, ensuring smooth and reliable power transmission. Aluminum alloy material has excellent heat dissipation performance, which helps to reduce the working temperature and improve the transmission efficiency. The surface of the aluminum alloy is finely processed and anti-corrosion treated, which not only has a delicate appearance but also enhances durability, providing solid and efficient protection for the powertrain.
