解决精密铸件缩孔问题的一些措施和技巧

Techniques and Measures to Solve Shrinkage Cavity in Investment Castings

由于精密铸造工艺的特殊性和局限性,某些精铸件经常出现难以有效补缩的热节点,造成缩孔、缩松缺陷。根据多年的工作经验,总结了防止精铸件产生缩孔、缩松缺陷的一些经验措施和技巧。

Due to the particularity and limitation of investment casting technology,hot spots often appear,which are difficult to effectively feed,resulting in shrinkage cavities and porosities.Based on the production experience,techniques and measures to prevent shrinkage cavity and porosity in investment castings were presented.
