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. Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpieces to be heated. Can we help? ## Benefits of Using Induction Heating for Hermetic Sealing 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. Induction offers a process without open flame. ## metal-glass sealing Application Notes Select from our collection of metal-glass sealing notes, developed over 40 years supporting our customers. Read how we helped to solve their process heating challenges! Soldering Ferrule and Module Assembly To heat ferrule and module assemblies for a soldering application in the fiber optics industry. 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 Hermetic Sealing a Ferrule & Fiber Optic Cable To heat a Kovar ferrule and fiber optic cable to 297 °F within 10 seconds for a soldering application, to form a hermetic seal Hermetically sealing a fiber optic cable in a kovar ferrule Induction heating provides instant start up time, requiring very little power resources, pin point accuracy, a clean source of heat which is easily integrated into existing automated systems soldering-a-kovar-piece-with-glass-to-a-copper-base 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 ## Our Systems for metal-glass sealing with Induction EASYHEAT Models Add your content here.
