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.

In cold chamber die casting, the alloy is forced into the mold cavity with such force and velocity that small quantities of air and gases are often trapped in the casting. If […]
