Metal-to-Glass (hermetic) Sealing with Induction
Hermetic sealing is the process of creating a container that is airtight. It is commonly used to encase electrical mechanisms, as well as to contain functional gases.
Metal-to-Glass Sealing with Induction
Our induction heating systems provide hermetic sealing processes with reliable, repeatable, non-contact and energy-efficient heat, focusing heat to a specific area of the part.

Heating a Kovar Ferrule for Glass Soldering
The solder formed a relatively uniform domed seal around the fiber despite the asymmetry of the open C coil. It took under 10 seconds to heat the part to soldering temperature
Soldering windows to time indicator housings
Soldering soda lime glass metal edged windows to steel time
Hermetically sealing glass-enclosed resistors
Induction heating provides precise, consistent heat to very small parts resulting in repeatable, quality seals. By heating with medium frequency, arcing (which occurs at high frequencies) is avoided.
Soldering a kovar piece with glass to a copper base for a photon light source
Induction heating provides ability to use same equipment for both assembly and repair, hands-free heating that involves no operator skill for manufacturing, and uniform control of heat from part to part
Hermetic sealing: SS rods & glass preforms
Induction melting provides hands-free heating that involves no operator skill for manufacturing, amounts of glass are precisely controlled by the glass preforms and even flow of glass creates aesthetically pleasing bond.
To heat selected areas of a glass lined steel tank to 16000 F in order to perform repairs of cracks and chips.
To heat a stainless steel housing to 18750 F in order to fuse a piece of R6 glass to the inside of the housing.
