1. Gravity casting: By precisely controlling the filling pressure (0.5-1.5MPa), the defects of pores and shrinkage are reduced, and the yield rate reaches more than 95%.
2. Laser etching + precision honing: The cylinder bore machining accuracy is controlled within ±0.05mm, the roughness Ra≤0.4μm, optimizes the oil storage performance, and reduces the noise of the cold engine.
