V process molding line

OPERATING PRINCIPLE vacuum process cast molding is a new metal molding technology and only adopt dry sand (no water, binder, tagger) It's automatic by a 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% TECHNOLOGY PROCESS Heat the EVA film Cover the heated EVA film on the mold(can be made from wood or aluminum) Spray a coating in a certain baume degree Put on the empty box sand-up the box and vibrate to compaction cover film on the full box vacuate the sand box lift box mould assembling vacuate the whole mould pouring loose sand box Vacuum process cast molding equipment and foundry equipment MAIN EQUIPMENTS Vacuum stablized system: Vacuum pump, Vacuum meter, Surge tank, dust removal tank, steam separator Molding system: Die shoe, Automatic roast Laminator, sand molding box , Vibrating table, Manipulator, Die lifter. Sand reclamation system: Sand screen, Elevator, Conveyor. sand bin Vacuum process cast molding equipment and foundry equipmentVacuum process cast molding equipment and foundry equipmentVacuum process cast molding equipment and foundry equipment 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 clean working environment eco-friendly save material reduce the labor intensity
