前言 挤压铸造是一种介于铸造与锻造之间,兼有铸锻特点的新型工艺。它的实质是对定量浇入铸模中的液态金属施加较高的机械压力,使其成形、凝固而获得零件毛坯的工艺方法。国内外有许多种名称,如“液态模锻”、“液态冲压”等,由于国际压铸学会将此定名为“squezecasting”,译其意,故本文选用“挤压铸造”这一名称。 与其它铸造工艺相比,挤压铸造具有:零件组织致密;无需浇冒口系统,金属利用 Introduction Squeeze casting is a kind of between casting and forging, both casting and forging characteristics of the new technology. Its essence is quantitatively poured into the mold of the liquid metal to apply a high mechanical pressure, so that its shape, solidification and parts obtained blank process. There are many kinds of names at home and abroad, such as “liquid die forging”, “liquid stamping” and so on. Since the International Die Casting Institute named this as “squezecasting”, this article uses the name “squeeze casting”. Compared with other casting processes, squeeze casting with: dense parts organization; no Riser system, the use of metal
