Cylinder head & cylinder block are two key components that make up the car engine. Their quality and manufacturing precision directly affect the engine's performance, fuel efficiency, reliability and service life.

HME Machining utilizes 3-axis CNC machining to improve economic efficiency and uses aluminum alloy, which has higher hardness and rigidity, can maintain shape stability at high temperatures, and is lighter than cast iron. Plating and sandblasting surface treatment processes can improve the material's oxidation resistance and remove surface dirt & oxide layers, making the surface smoother and more even. The final product boasts a surface finish of 0.4 microns, the roundness tolerance of ±5 microns, the flatness tolerance of ±5 microns and the diameter tolerance of ±5 microns.
