Fluorescent Penetrant Inspection (FPI)

Fluorescent Penetrant Inspection (FPI) is a process by which a high sensitivity dye is applied to a non-porous material in order to detect defects in the substrate.  FPI ranges from low sensitivity, similar to red dye inspection to high sensitivity penetrants requiring several steps in order to develop the fluorescent dye to find minute defects in the substrate. Sinto Surface Technologies can arrange for these services through a local qualified and certified partner to provide this service.

As FPI typically precedes other surface modification processes, this can allow us to bundle capabilities to provide one-stop-shop services.

• Aerospace approved high sensitivity FPI processing
• Convenient local processing of components managed by the Sinto team
• Allows for “One Purchase Order” approach to surface processing needs
