When the die is closed the only openning is through the Chill Vents where the molten metal should get trapped and solidified to make sure there is enough pressure inside the die cavity for production of good quality casting. Chill Vent material must have excellent thermal conductivity and wear resistance.
A robust vacuum system reduces machine down time, production cost and energy. In addition, the casting will have high quality surface finishing.
Large venting profile provides maximum air suction
Reduce scrap rates
Enable casting of larger, thinner and more complex parts
Increase product density and strength
Reduces rate of rejection
Ensures good surface finish for plating or powder coating
Reduces shot pressure
Increases mold life
Increases density of product
Used for aluminum, magnesium zinc, or brass
Easy to add to any cold chamber die casting process
Maintenance is minimal
