Glass to metal sealing
Since the creation of the department dedicated to hermetic products, Conesys Europe has mastered the difference glass-to-metal sealing processes in order to meet a maximum of demands for hermetic products.
Conesys Europe hermetic connectors are obtained from a set of technological bricks covering all industrial glass-to-metal sealing processes.
Introduction to glass-to-metal sealing processes
Glass-to-metal sealing processes are all based on a technical solution consisting in melting the glass with metal parts to be assembled under controlled conditions.
These processes make it possible to obtain a perfectly sealed barrier between two environments while ensuring the transfer of electrical signals between these two environments.
The benefits of glass-to-metal sealing
There are multiple advantages to glass-to-metal sealing and provide high performance connectors:
- Use in a vacuum
- High resistance to corrosive environments
- Robust sealing barrier
- Resistance to high temperatures (up to 350°C)
- High resistance to shocks and vibrations
- Stability and resistance to thermal shocks
- Small size and made-to-measure
Mastery of glass-to-metal sealing
The quality of the implemented processes is based on the mastery of technological bricks specific to glass-to-metal sealing.
The quality controls applied to glass-to-metal sealing guarantee, in particular, dimensional, electrical performance, and hermetic compliance.
Which glass-to-metal sealing for which use
Currently 4 types of glass-to-metal sealing are available. The type of glass-to-metal sealing is chosen depending on the intended use of the hermetic electrical connector.
Matched glass-to-metal sealing is primarily used for signal processing and requires complex design and extremely demanding industrial control.
The main materials used are FeNiCo controlled expansion alloys (iron, nickel, cobalt).
Special sealings are characterized by a glass-to-metal sealing primarily used for signal processing in extreme temperatures, high pressure, and corrosive sulfur environments.
The main materials used are titanium and nickel alloys.
