Hermetic Sealing with Induction

How does Metal-to-Glass Sealing with Induction Work?

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.

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.
