Compared with the traditional sand casting process, the castings obtained by precision casting are more precise in size and have better surface finish. Precision casting is also called lost wax casting. The wax mold is made based on the shape and structure of the casting, and then the outer casting sand shell is made by glue and coated sand on the outside of the wax mold. By heating the outer casting sand shell, the internal wax mold is melted and flows out. Subsequently, the metal liquid can be poured into the outer casting sand shell to achieve casting. The completed casting needs to be broken by the crushing device. The outer sand shell; the current crushing device is mainly composed of a frame, a crushing impact hammer and a crushing platform.
