Complete Hermetics provides custom designed ceramic-to-metal seals and feedthroughs for applications where high operating temperatures, high voltage and harsh environments are required as compared to glass-to-metal seals. These seals are more labor-intensive that glass-to-metal and therefore take longer to produce. Complete Hermetics can work with you to design custom ceramic-to-metal hermetic feedthroughs and seals for all your applications and needs.
Complete Hermetics manufactures custom made ceramic-to-metal hermetic feedthroughs and hermetic seals. We specialize in ceramic-to-metal seals for high vacuum feedthrough and electrical feedthrough applications.
Contact Complete Hermetics for more information about unique solutions for ceramic-to-metal and ceramic-doped glass feedthroughs and seals.
