[0002] Both V-process casting and lost foam casting adopt vacuum forming, but the process flows of the two are quite different. V-process casting is named after the first letter "V" of the English word "Vacuum". The biggest advantage of V-process casting over traditional sand casting is that it does not use adhesive. In V-process casting, a plastic film is used to seal the sand box, and the air in the mold is extracted by a vacuum pumping system. There is a pressure difference between the inside and outside of the mold, which makes the dry sand compact and forms the required cavity. After the core is placed, the mold is closed, and the casting is poured and vacuumed to solidify the casting. Then, the negative pressure is released, and the sand collapses to obtain the casting.
