Vacuum Impregnation Description:
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.
Here at Anoplate we are typically asked to provide this along with another finish such as Chemical Film on an Aluminum casting.
