The ratio between volume of the valves and suctioning power is optimal. The Fondvacuum® system is perfect also for the diecasting sites and for very complex very small molds.
With proper usage, they can be used for approximately 20,000 cycles without maintenance.
The closing of the valve in a millisecond – operated by the kinetic force of the metal flow – prevents even the smallest metal particles from penetrating.
Furthermore, the valves are precisely lubricated at every cycle, the valves have their own thermic regulation system, and the actuator mechanism works with no friction.
