Company Profile

Tekna Seal, a custom manufacturer of hermetically sealed connectors, glass-to-metal feedthroughs, hermetic seals, lithium battery seals, and ceramic to metal seals is a Minnesota company which was founded in 1979 primarily to manufacture insulated hermetic feedthroughs for implantable devices and batteries associated with implantable devices.  Shortly after inception, it was realized that there were many opportunities for selling glass-to-metal hermetic feedthroughs in other markets including automotive, aerospace, high performance sensor packages for severe industrial processes, and critical military applications. 

In 1990, we developed a unique glass-to-metal sealing process that allowed us to improve the performance and reliability of our hermetic seals substantially over the common sealing practices found throughout the industry. This process does not require pre-oxidation of the metal components. 

This relatively simple difference has many advantages including:

The lack of oxide formation also means that there is not a requirement for post hermetic sealing oxide removal.  This provides:
