Abstract
In the process of Lost Foam Casting,the mold with high concave cavity is easy to cause the real dead angle for compaction,the sand is difficult to fill and the compact effect is not enough.The coating can not be effectively supported the liquid metal and damaged in this step,resulting in sand burn defect in the castings.In order to solve this problem,using precoated sand instead of resin sand process in dead comers,the effect is very good.关键词
