  Aluminum die casting piston, its forming method is called squeeze casting. The commonly used piston is al-Si alloy, forming for gravity casting, after heat treatment, processing, surface treatment and so on.



   For high-load pistons, al-Si alloy is formed by extrusion casting. For pistons with higher loads, the difference is that Al-Si alloy is formed by forging.


   There are many kinds of Al-Si alloys used.There are many processing methods, for ring groove, pin hole, outer circle, high processing accuracy requirements. Surface treatment methods are also many, tin plating, graphite coating, hard oxygen and so on.
