V process casting machine is called vacuum seal casting molding machine. It’s 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 V process casting machine has been ranked as Cleaner Production Directory because of its high sand recovery rate, high material utilization as well as its eco-friendly advantage. So far, V process has been successfully applied in the construction machinery counter weight, petroleum machinery(including crank, reduction case, counterweight), belt pulley, swing bolster, axle, brake drum, piano plane, manhole cover, high manganese steel lining board.
Full automatic V process molding lne
Now we are the only company who can produce full automatic V process molding line, the mold is running on line is difficult, because Vacuum process mold can not stop negative pressure, our comany have break through technical problems.
V process line advantages
*Superb finishes. *Good dimensional accuracy. *No defects from gas holes. *All sizes and shapes of castings are possible from thin walls to thick sections, or from castings weighing ounces to several tons. Sand thermal conductivity is lower and metal fluidity is improved. Solidification time is slower. In addition, zero draft designs are common, and can reduce clean up and rough machining operations. *Most ferrous / non-ferrous metals can be used. *Low operating cost - You not only save on the cost of sand binders but all of the cost of sand mixing, testing and disposal/reclamation. Even pattern life is extended because the sand never touches the pattern and it is never subjected to the rigors of a conventional molding machine. Finally, V-Process produces castings with fewer imperfections and less scrap.
