[0002] V-process casting is a casting technology that uses vacuum forming. The biggest advantage that distinguishes it from traditional sand casting is that it does not use adhesives. V-process casting uses a plastic film to seal the sand box, and relies on a vacuum pumping system to extract the air inside the mold. There is a pressure difference inside and outside the mold, which compacts the dry sand to form the required cavity. After core setting, mold closing, and pouring, vacuum is applied to solidify the casting. The negative pressure is released, and the molding sand collapses to obtain the casting. Therefore, a film covering device for V-process casting is required during the V-process casting.
