“CASTvac, reliable, efficient & economic”www.wandatechnology.com

• Up to 5 times of venting area for air flow but using the same clamping force as 2D chill vent

• No machine stoppage caused by aluminium blockage as occurred when using mechanical valves

• Cost saving by USD 90,000 per machine per year when changing the mechanical valve to CASTvac

Developed by CSIRO Australia, globally patented, extensively adopted in Nissan Casting Australia and in the major die casting plants in China.

Vacuum Valve for Die CastingCASTvac™

OTHER CONTACTS:

CASTvac MV series is designed to substitute the mechanical valves. They can be fitted into the existing die pockets. A spring-loaded ejection mechanism is built in the valve body. Current MV models include:

CASTvac CV series uses ejector pins driven by the die ejection plate in the moving side, but the fitxed side has its own built-in ejector pins, the same as the MV series. The proposed models include:
