Vacuum Impregnation

Vacuum Impregnation

What is Vacuum Impregnation? 

Porosity, holes, cracks and tiny voids in castings and powder metal parts are unavoidable. In harsh environments that your parts operate in, these fissures can allow moisture and other corrosive agents to enter leading to part failure. Similarly, parts which circulate fuel, oil or hydraulic fluid under pressure require leak-free components. Vacuum pressure impregnation (VPI) assures sealed parts that will retain pressure requirements and prevent leakage.

Vacuum impregnation prevents migration of fluids or gas under pressure from contained areas – more simply put vacuum impregnation stops leaks. The ultimate goal of vacuum impregnation is to seal leak paths and porosity without impacting the functional, assembly and appearance of the part. Vacuum impregnation is governed by military specification MIL-STD-276A as well as proprietary corporate standards.
