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.
铝合金压轴活塞，其成型方式称为挤压铸造。
常用的活塞是Al-Si类合金,成型为重力铸造,经热处理、加工、表面处理等等工序。
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.
对于高负荷的活塞,用Al-Si类合金,成型则为挤压铸造,对于更高负荷的活塞,用Al-Si类合金，与高负荷活塞的不同便是它是通过锻造成型的。
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.
所用Al-Si类合金的种类很多。加工的方法也很多,对于环槽、销孔、外圆,加工精度要求很高。表面处理的方法也很多,有镀锡、石墨涂等。
