MORE THAN JUST DELIVERY
A special glass feedthrough, also called a bolt feedthrough, current feedthrough, flange feedthrough and cable feedthrough, which usually consists of a pressure body, the contact pin(s) and the glass body (insulator), can be individually designed depending on the intended use.
It can be integrated into complex technical structures, such as measuring heads or sensors, through soldering, bonding, welding or screwing, depending on the application. The processing of highly refined steels and novel materials such as titanium and tantalum is just as much part of our services as the use of technical glass and high-performance ceramics. In-house surface finishing of the contact pins and/or the outer surfaces of special glass feedthroughs facilitates contact through soldering, plugging or bonding.
