Chill Vents

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.

PURPOSE

A robust vacuum system reduces machine down time, production cost and energy. In addition, the casting will have high quality surface finishing.

FUNCTION

Eliminate porosity

Large venting profile provides maximum air suction

Reduce scrap rates

Enable casting of larger, thinner and more complex parts

Increase product density and strength

BENEFITS

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
