V Method Production Line
Vacuum seal modeling technology (also called the V method modeling) is the 1970 s Japan
invented and the successful development of a special casting method. Is the single dry
sand (don't add water, binder and affix) for sand, with plastic film in the heal with the vent
and suction device on the shape of the coated forming, seal sand box, and depend on a
pump type internal air, causing casting on internal and external pressure compelling dry
sand get light and needed for the formation of cavity with a physical modeling method.
V the main process modeling method for film coating, coating, filling sand on tight, the
mould and so on, these processes in vacuum under the support of the complete. Its basic
equipment is: take suction filter tube sand box templates, vacuuming system, plastic film
heating, molding and cut off, and earthquake real stations and sand treatment equipment, etc.
