Vacuum Impregnation

Vacuum Impregnation Description:

Vacuum Impregnation is a sealing treatment of porous castings with a medium by filling the pores with a thermosetting polyester resin under pressure to stop pressure leaks.

The castings may have leaks, cracks, and voids that are created in the base material during the manufacturing or subsequent machining processes.

Vacuum Impregnation Benefits:

Eliminates Leaks

Greatly Reduces Scrap

Eliminate In Process Testing

Extends Tool Life - particularly in powder metal parts

Vacuum Impregnation Applications:

Gear housings that contain grease or oils

Valves that contain liquids or gases

Electronic housings that must not allow moisture to enter and ruin the components

Hydraulic parts that must retain fluid pressure

Lens housings that require no moisture from entering and causing distortion

Air powered tool components

Microwave components

Vacuum pumps

Compressor parts

Parts that must be submerged in water or fluids

Computer parts in super clean systems

Fluid cooled parts
