core collapsibility

基本解释

The core with soluble salt and high collapsibility was used for the parts with complicated cavities.
对复杂内腔的零件，可用可溶性盐芯和易溃散砂芯解决难成型问题。
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.
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 resin sand with high collapsibility is chosen to make the core of the near closed hollow ring on the basis of many technological experimentations through analysis of structure and process.
通过结构分析和工艺分析，在大量工艺试验的基础上，选用高溃散性树脂砂制作型芯，并成功地研制出大型薄壁复杂结构的封闭型腔铸件。
