V Method Molding: a Physical Mehtod by Using of Single Dry Sand

A. Item Description

Vacuum seal molding named V technique molding, the process is a physical technique by utilizing of solitary dry sand(no drinking water binder and appendages), molding by plastic movie with vent and suction products, following heating and then sealed the sand box, pumping out air by vacuum pump, the stress compact the dry sand to the needed condition.

Typically the method  casting line contains molding models and sand processing units. The main tools are as adopted:
Molding models: pattern-film masking tools-movie stretching plate-molding sand lender-vibrated table-vacant box switch more than machine-drying tools-sand box-maniplator and others.

Sand processing models: shaked out grille-vibrating conveyor sand device-magnetic separator boiling cooling classifier and other.
