Induction metal-glass sealing Benefits
-
Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
-
Increases production rates with faster heating cycles
-
Reduces defect rates with repeatable, reliable heat
-
Eliminates variability from operator-to-operator, shift-to-shift
-
Maintains metallurgical characteristics of the individual metals

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.
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
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 a stainless steel housing to 18750 F in order to fuse a piece of R6 glass to the inside of the housing.
To heat selected areas of a glass lined steel tank to 16000 F in order to perform repairs of cracks and chips.
