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
