Casting impregnation technology is now used world-wide as a matter of course and impregnation systems can be found in all the major automotive, engineering, defence and aerospace industries.
Vacuum impregnation is a process that fills micro porosity and small voids ensuring components don’t leak in service. It is also a potential route to salvage expensive components. Many OE manufactures now specify the impregnation process as part of a belt and braces approach to eliminate any service failures.
Typical application would include oil and water pumps, pneumatic valves fuel systems and anywhere components need to be pressure and leak tight.
