一、序言压力铸造是先进的热加工工艺之一,用压铸法可以制造很复杂的薄壁零件。压铸件具有表面光滑,轮廓清晰,尺寸精确,加工余量很小或不经加工即可装配。压铸件的显著特点是强度高,组织致密,生产率高,具有一定的技术经济上的优点。近年来在国民经济的各工业部门得到广泛应用。主要压铸铝、锌及铜等有色金属铸件。
First, the preface Pressure casting is one of the advanced thermal processing technology, using die-casting method can manufacture very complex thin-walled parts. Die-castings have a smooth surface, clear outline, accurate size, machining allowance is small or can be assembled without processing. Die casting is characterized by high strength, dense structure, high productivity, with some technical and economic advantages. In recent years, it has been widely used in various industrial sectors of the national economy. The main die-casting aluminum, zinc and copper and other non-ferrous metal castings.
