Abstract
A vacuum impregnation system and processes that subject a part to a vacuum, immerse the part in a polymer impregnating liquid, and apply positive pressure to the part to introduce the polymer impregnating liquid into part porosities, releasing the pressure to atmospheric pressure and solidifying the polymer impregnating liquid, preferably without an active polymerization step.
