Electrical Feedthroughs

Maintaining Hermetic Seals With a Glass-to-Metal Bond

It’s hard to imagine that a furnace and x-ray equipment using some of the same technology, but electrical feedthroughs are vital to many different applications which require a hermetic seal with an electrical feedthrough that prevents even the tiniest amount of leakage in the vacuum. When your business needs a prototype that has been tested and retested for your project, Complete Hermetics has the engineers who can make it happen.

For glass-to-metal seals, we heat glass to its molten state, then its wetted to the metal to create the bond. Our production team carefully measures the thermal expansion of the glass to prevent breakage during its use. Glass seals are more resistant to the temperature changes during use than an O-ring or epoxy seal. We can also match the use of the glass-to-metal seal to your electrical feedthrough, making your system more efficient and secure under stringent conditions.

Glass-to-metal seals and electrical feedthroughs can have plating to help them resist corrosion and increase the soldering capabilities. With so many options for the seal, you can get the exact specifications that meet your application. Our engineers specialize in creating hermetic seals and electrical feedthroughs. You know what you need your product to do. Let us help you make it happen by producing the parts that make it work.

Understanding Electrical Feedthroughs

Glass-to-metal seals are more effective than O-rings and epoxy when it comes to maintaining an hermetic seal. Sometimes, glass isn’t effective at high voltage or high operating temperatures. The solution is a ceramic-to metal seal and electrical feedthrough. Although there is more labor and time involved in creating this type of seal, it will work under harsher conditions than the glass-to-metal seal might.

Our engineers specialize in ceramic-to-metal seals and electrical feedthroughs to match your specifications. We design and develop prototypes and manufacture products which provide a tight seal. Every item is tested and retested to ensure its properties and effectiveness for use. We have multiple options for insulators, conductors, and housing materials to fit the industry in which it will be used. Using the right products makes the difference in the end not only in effectiveness, but in your bottom line.

Electrical feedthroughs are vital to many applications in medical technology, defense, satellites, and optics. Our team has a wide range of knowledge to get the job done right. Together, your developers and ours can make sure your product works like it should every time. You know what you need, but not how to create it. We have the know-how to design and develop the hermetic seal and electric feedthrough to fit your specifications. Let us work with you to make your project move forward by contacting us.
