挤压铸造是将锻造和铸造合一的金属加工工艺。有时也叫金属液态模锻。它是对凝固过程的金属施加压力以便压铸出各种形状的精确零件,其组织结构,机械性能和表面光洁度均得到改善,并且成本低,可适用于黑色、有色金属及合金。一般工件的最小厚度为6.3毫米为宜。本文对这种工艺的历史及今后的发展提出一些看法。铸造和锻造工艺,它们都发展很快,但很少发现有任何工厂将这二种工艺合为一种。铸造是将溶解的金属作为成型材料,而锻造是使用固态金属。尽管这二者有明显的不同,但完 Squeeze casting is forging and casting of metal processing technology. Sometimes called metal liquid forging. It applies pressure to the metal in the solidification process to die-cast precise parts of all shapes, with improved microstructure, mechanical properties and surface finish, as well as low cost for black, non-ferrous metals and alloys. General minimum thickness of the workpiece is 6.3 mm is appropriate. This article puts forward some views on the history of this technology and its future development. Foundry and forging processes, they are developing rapidly, but rarely found any one plant these two kinds of technology into one. Casting is to dissolve the metal as a molding material, and forging is the use of solid metal. Although there is a clear difference between the two,
