Casting Impregnation

Our Vacuum Pressure Impregnation System (VPI) is used to seal the porosity that can naturally occur with in a casting. The castings are placed into a the VPI where the air is removed and sodium silicate is introduced. The drop in pressure forces the sodium silicate into any fishers or voids creating a sealed pressure vessel. Once impregnated the castings are subjected to a pressure vessel analysis to verify their integrity.
