Custom Vacuum Sealed Assemblies
Engineered vacuum enclosures built for UHV, high-pressure, and extreme thermal cycling—designed to survive space, subsea, and sterilization environments.
Precision Hermetic Systems, Custom-Built for Mission-Critical Use
Advanced Hermetic Solutions designs and fabricates precision vacuum sealed assemblies using a range of joining techniques including vacuum brazing, glass sealing, and laser welding. These assemblies are leak-tested, application-tuned, and documented to meet aerospace, defense, and scientific instrumentation requirements.
- UHV-compatible materials and processing (< 10⁻⁹ torr)
- Multi-port feedthroughs and instrumentation headers
- Compatible with bake-out, sterilization, or nitrogen purge cycles
- Integration of optical windows, electrical connectors, and cooling channels
- Leak testing via helium mass spectrometry and gross bubble testing
Assemblies are available in low-volume pilot runs or repeat production batches, with documentation tailored for flight, cleanroom, or validation protocols.
Engineering Factors in Vacuum Sealing
- Geometry: Cylindrical and domed shapes improve uniform stress distribution in high-pressure environments
- Joint Method: Brazing is preferred for thermal resilience; TIG/GTAW welding for metallic-only builds; laser welding for tight joints
- Material Pairing: Kovar and Alloy 42 offer matched expansion with glass and ceramic; SS and Inconel for thermal or corrosion resistance
- Outgassing Control: Use of UHV-compatible alloys and high-temp bakes to reduce trapped gas evolution
- Mounting Interface: Weld rings, bolt patterns, or integrated collars available to fit your mating hardware
