Vacuum Process Casting Foundry Machine

We are engaged in manufacturing, exporting and supplying of Vacuum Process Casting Foundry Machine from Qingdao, Shandong, China which is a new metal molding technology and only adopts 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. Relase little dust,so it's eco-friendly. And the sand recovery rate can reach at 95%.
