Product Details
Simple Introduction Vacuum process molding line is an emerging molding process which invented and developed successfully from Japan in the 1970s. It adopts unit sand as molding sand, using plastic film coated forming in the mould with air vent and air extractor after heating, sealed box, vacuating the molding, causing pressure difference between molding inner and outer makes dry sand compact to form needed mold cavity. The basic equipment of vacuum process is: sand box mould with vacuum, vacuum pumping system, plastic film heating, molding and cutting off, vibrating table, sand processing equipment and so on. Our company has world leading vacuum process molding technology. We can design different vacuum process molding equipment and corresponding sand processing equipment. Vacuum process molding technology has developed well during the recent years by the higher degree of automation, higher quality of casting, high precision, no pollution, saving energy, improving working environment and so on. Vacuum process molding casting surface quality is good, less casting defect, easy stripping, high precision casting dimension. Molding sand doesn’t use binder, totally recycling, reducing the mineral cost, so it is applied in more and more fields. Operating principle vacuum process cast molding is a new metal molding technology and only adopts dry sand (no water, binder, tagger) It's automatic by an electric control system. Make use of the heated EVA film covering on the model to seal flask. Take out the air with vacuum pump. The sand mould is tightened by pressure difference. Pouring to form the casting The course is physics molding way. Release little dust, so it's eco-friendly. And the sand recovery rate can reach at 95%. Advantages of this system Take good use of sand, the material recovery rate is 95% low cost good casting dimension accuracy save labor cost keep cl
