Vacuum Pressure Vessel / Impregnation Autoclave

Vacuum Pressure Impregnation technology effectively infiltrates liquids into various materials and devices. It accomplishes this through the application of vacuum and/or pressure techniques. This technology boasts diverse applications, ranging from enhancing electrical coil winding insulation to treating wood and graphite. Its implementation results in a superior product, achieved in a shorter timeframe and at a reduced cost. In fact, Vacuum Pressure Impregnation equipment offers a highly efficient alternative to traditional dip and bake methods.

Application of Impregnation Autoclave

Vacuum Pressure Impregnation excels in treating wood, impregnating resins, and numerous other industrial processes, encompassing carbon and wood product manufacturing to metallurgy. Our VPI autoclaves offer an economical solution, serving as a viable alternative to traditional dip and bake methods for processing electrical windings, armatures, castings, and powdered metal products.


Impregnation Autoclave Process Types Follow The Four Steps:

  • Utilizing vacuum (and pressure), we infuse the sealant deeply into porosity/leak paths for effective impregnation.

  • To eliminate excess sealant, we employ gravity, rotation, or centrifugal force for efficient recovery.

  • The wash/rinse station ensures thorough cleaning, removing residual sealant from internal passages, taps, pockets, and other intricate features of the part.

  • Finally, the cure station completes the process by polymerizing the impregnated sealant within the leak path, ensuring durability and reliability.


In addition to fully or semi-automated standard systems, we also offer custom engineered solutions to meet your individual requirements, all backed by worldwide after sales and service support from the market leader in impregnation sealants, equipment and service. Whatever your needs, we can meet them completely.
