Abstract：
With the lost foam industry booming, more and more foundries had begun to realize that ceramic sand as the elimination of the advantages of the backing sand. Ceramic sand has near spherical shape, good flowability and a higher permeability, it can be filled with elongated holes, steep located castings and the complex part with cavities. Ceramic sand is relatively easy to shakeout although it has higher strength while molding. Ceramic sand is difficult to be broken while reclamation so it generates less sand powder. Also, ceramic sand can reduce the cost of casting production, improve the workshop labor environment.
