Process of lost foam casting process can save cost and produce products with high quality,so it is widely used by plenty of manufactures in various parts of the casting. In fact,this technology is also used in the compression body. Compared with the previous process of traditional production, the defects of the castings produced by the method of lost foam casting process will be greatly reduced.Even accurate use of the technology will almost make castings to achieve zero defect.The process of lost foam casting process canceled the sand mulling and core making process.It also eliminates the traditional model of flask separating,drawing,patching,core setting and other complicated operations which simplifies the shakeout, casting sand cleaning and sand conditioning greatly.Thus the process has shorten the production cycle.

Further more,there are plenty advantages of the lost foam casting process.On the one hand, because of the large stiffness of casting mould under the negative pressure,and the iron casting is easy to achieve self-complement which will reduce the riser size of the casting;On the other hand, much freedom for assemble of the foam model cluster is easy to implement multiple casting for one type and increase the technological yield.With higher labor productivity and less production personnel, the workers needed for the process of lost foam casting process are significantly less than the traditional process of green sand mold casting.
