Vacuum Impregnation is a sealing treatment of porous castings with a medium by filling the pores with a thermosetting polyester resin under pressure to stop pressure leaks.
The castings may have leaks, cracks, and voids that are created in the base material during the manufacturing or subsequent machining processes.
