Heating a Kovar tube for a glass sealing application

The client was using a torch, and operator error was slowing the heating. The repeatability of induction enables improved throughput while in this process it is a more efficient heating method than torch heating, also reducing scrap

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.
