铸铝件造型制芯技术的现状与发展

The Review and Prospect of Mold and Core Making Technology for Al Castings

综述了铝合金铸件生产工艺的现状与发展，指出随着汽车工业对高质量铝铸件的需求日益增加，铝合金铸造技术将得到很快的发展。开发铸铝件专用粘结剂、改善型芯砂的溃散性、防止环境污染等将成为今后铸铝件生产技术发展的主要方向。

The precent progress for Al alloy casting is reviewed. It is pointed out that the mold and core making technology will be developed rapidly in order to meet the need of increasing Al castings in automobile industry. There is a main tendency for Al castings to develop binders for mold and core, improve collapsibility of mold (or core) sand as well as prevent from environment pollution.
