Vacuum Degassing removes trapped gases from compounds such as resins or epoxies which become entrapped in the mixture when mixing the components. If not removed before the material cures, gas bubbles will cause defects such as nodules, cavities, or hollows in the finished cast. Vacuum degassing can improve the quality of products and shorten processing cycles.
When a mixture is put into a vacuum degassing chamber and the air pressure above it reduced, i.e. evacuated, the gas bubbles which formed at atmospheric pressure expand and rise to the surface where they burst and the gas released is pumped away.
Alternate methods can be used to remove or minimize the quantity of gas bubbles, but vacuum technology used in degassing applications can improve the quality of products and shorten processing cycles.
