所谓挤压铸造（squeeze　casting）就是在相当高的压力作用下使金属熔体或浆体（半固态）充型和凝固的精密铸造工艺。这种工艺近几年在国内外均取得了长足发展,已成为汽车、摩托车、电器与电子产品等行业高档有色金属特别是铝、镁合金零部件大批量生产的重要生产方法。截止到2001年底全世界保有挤压铸造机约1050台,其中中国约有100台,从日本进口的有7台。 So-called squeeze casting is a precision casting process that charges and solidifies a metal melt or slurry (semi-solid state) under relatively high pressure. In recent years, this kind of technology has made great progress both at home and abroad. It has become an important production method for mass production of high-grade non-ferrous metals, especially aluminum and magnesium alloy parts in automobiles, motorcycles, electrical appliances and electronic products. By the end of 2001, there were about 1050 squeeze casting machines in the world, of which about 100 were in China and 7 were imported from Japan.
