In order to increase strength to weight ratio of casting, the casting needs to be heat-treated. The heat treatment temperature could go as high as 400ºC and for as long as 24 hours. The air trapped inside could expand and cause blistering during heat treatment, especially for aluminum alloys.
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
