Glass-to-Metal Sealing Solutions

Mission specializes in both matched seals and compression seals, offering customized solutions to ensure optimal hermeticity for various applications. Our proprietary oxide-free sealing process allows the use of a wide range of metals, including stainless steel, Kovar, molybdenum, and other exotic alloys.

Our in-house capabilities extend beyond sealing to include precision metal stamping, plating, forming, and welding fine metallic ribbon, allowing for full-service manufacturing of hermetic connectors and feedthroughs. Whether for highly specialized applications or standard components, we provide tailored solutions to meet your needs.

How Glass-to-Metal Seals Work

Glass-to-metal feedthroughs use metallic conductors that pass through a sealed metal housing. Sintered glass rings or glass tubing segments are fused around the conductors to provide:

  • Electrical insulation
  • Mechanical strength
  • Precise conductor alignment

The choice between matched seals and compression seals depends on the specific application. If you're unsure which sealing method is best, our team can guide you in selecting the optimal solution.

Protecting Sensitive Electronics

Hermetic packaging is essential for safeguarding electronic components such as sensors, laser diodes, optoelectronic devices, and crystal oscillators from harsh environmental conditions, including:

  • Corrosion
  • Humidity
  • Extreme temperatures

Mission’s advanced hermetic sealing technology ensures reliable, long-lasting protection for critical electronic systems in even the most demanding environments.
