V-process casting, the third generation of physical molding method after the mechanical molding method and the chemical molding method, was originated in Japan in 1969.This method has the advantages of simplifi ed mold making with unbonded sand, high dimensional precision in casting, easy peeling and high return rate of sand at 95% etc. After several decades of development, it becomes a mature technology.Although in recent years the developed countries have reduced their casting production, the superiority in environmental protection and emission reduction of V-process makes it still a prominent technique.
