What is Casting Impregnation?
Casting Impregnation
Casting Impregnation is the process of removing air from the pores of leakage paths in a casting and replacing it with resin that is specifically formulated to cure in the pores so that the casting becomes pressure tight.
How does it work?
It is a method of sealing porous materials without impacting the functional or dimensional characteristics of the material. The impregnation process can provide:
- Sealing
- Reduced moisture and internal corrosion
- Enhanced integrity
Why is it important?
It is important because when parts are created by casting metal, tiny defects are nearly impossible to avoid. Whether those defects involve porosity of the surface, bubbles or other types of incursions, they can negatively impact a part’s performance under operating conditions.
