Full Mold Vacuum Process Casting Molding Line

Product Detail

This machine is designed and made by our company.It's a Patented Product. It has good function like a complex molding line.It can make different castings which fit for the v process. 
Vacuum Process Foundry Molding Machine Line is called vacuum seal casting molding equipments Line. It is a kind of dry sand casting molding machine which adopts no adhesive. Based on the pressure produced by the vacuum pump, it takes use of the EVA film to make a vacuum sealed condition. Then the dry sand will be tightened, and getting a mould. The finished casting’s quality is very good after pouring. Our Vacuum Process Foundry Molding Machine Line has been ranked as Clearner Production Directory because of its high sand recovery rate, high material utilization as well as its eco-friendly advantage. So far, Vacuum Process Foundry Molding Machine Line has been successfully applied in the construction machinery counter weight, petroleum machinery(including crank, reduction case, counterweight),belt pullery, swing bolster, axle, brake drum, piano plane, manhole cover, high manganese steel lining board
