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
