How It Works 

Two key characteristics differentiate the V-Process from conventional sand casting.

First a thin plastic film is heated to its deformation point and then vacuum-formed over a pattern on a hollow carrier plate.

Second, the process uses dry, free-flowing, unbonded sand to fill the specialflask set over the film-coated pattern. 

 

Why it's sand recycling rate can reach to 95%

The sand used contains no water or organic binders and is kept under a vacuum during molding. Permeability of the sand is not a concern, as in green sand, which is why finer sand can be used and improved finishes are achieved.  The flask is then covered with a second sheet of plastic film. The vacuum is drawn and the sand becomes rigid. Releasing the vacuum originally applied to the pattern permits easy stripping.
