V-Process sand molding machine Roberts Sinto

V-process molding takes advantage of an abundantly available, totally reliable and almost free natural phenomenon to bind molding sand in place... Atmospheric Pressure!

With V-process molding you eliminate many of the costs and problems associated with conventional green sand and no-bake molding.

Because the V-Process uses clean, dry unbonded sand, you can forget about mullers and mixers, and costly sand reclamation and reconditioning equipment. Most V-Process users require only sand cooling and transportation, dust collection and simple screening to remove tramp metals.

Molding equipment is simple too. It can be limited to as few as five items (a vacuum system, Film heater, vibrating table, pattern carrier and flasks) or automated for higher production. There is no need for heavy, noisy jolt squeeze equipment, ramming of slingers.

The molding media is clean and dry therefore shakeout equipment is usually nothing more than a grate to allow the sand to flow away from the casting and back into the sand system. Fume and odor control is unnecessary in most applications.

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.
