Generally speaking, the advantages of green sand casting process include low price, simple production equipment, various unit weight (from 0.1 kg to 500 kg or bigger), and various structure of castings. Moreover, it can meet various quantity production requirements. Reasonably, the disadvantages of this process will be comparatively bad surface quality, more casting defects, and bigger dimensional tolerance.
