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. Relase 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
