Impregnation Methods from Imprex - Vacuum Pressure Sealing

Vacuum Pressure Impregnation Methods

Equipped with a variety of in-house VPI systems, Imprex uses impregnation methods designed to provide anaerobic vacuum-only, small-batch resin, electrical component resin, dry or wet vacuum oil impregnation, and dry vacuum pressure thermo-set resin processes.

For maximum sealing results, our dry vacuum impregnation systems seal extremely small pores in parts that must operate in high-pressure environments. This process is vital for military applications, meeting all MIL-1-17563C specifications and requirements.

In-House Processing

  • Thermo-Set Resin Systems for Castings of Any Size
  • Anaerobic Vacuum-Only Systems
  • Small-Batch Resin Systems
  • Dry/Wet Vacuum Oil Impregnation Systems
  • Resin Systems for Electrical Components

Wet Vacuum Application

Wet vacuum impregnation performs best with powdered metal and sintered metal parts. Wet vacuum offers fast cycle times and easy operation.

Dry Vacuum Pressure Application

Dry vacuum pressure application is recommended when sealing porosity is very small and sealing requirements are most stringent. The dry vacuum pressure application provides optimum sealing results for high-pressure requirement and is the required process for compliance with MIL-1-17563C.

Imprex-e Electronic Component Sealing

Our casting impregnation shop is known for its work on sealing electronic components. Just as with porous castings, electronic components need to be protected from moisture, humidity, solvents, fluxes, and corrosive agents. Imprex-e offers impregnation services for electronic connectors, wiring harnesses, cable assemblies, coils, sensors, solenoid valves, and more. In the leak paths between metal leads or wires and the molded plastic, the Imprex-e process seals electronic components from the inside out.
