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 resistorsHermetically 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 SolderingHeating 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

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 preformsHermetic 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.
