TRIDELTA business group
As our company has evolved from the porcelain factory founded in 1890 to today’s innovative TRIDELTA business group, so have our products also adapted to the progress of modern technology. In the early 1950’s hard and soft magnetic ferrets were developed as another ceramic product line in today’s controlling company TRIDELTA GmbH (formerly Keramische Werke Hermsdorf). Since then the company has grown into a major ferrite producer in Europe.
The philosophy of TRIDELTA GmbH is based on the development of products and solutions that are innovative and individually tailored to customer needs.

TRIDELTA Campus Hermsdorf
Hightech-location for ceramics and electronics in central Germany
The location initiative was founded in December 2017 by 23 companies from Hermsdorf and the Fraunhofer Institute for Ceramic Technologies and Systems.
Hermsdorf is considered a traditional location for technical ceramics. Shortly after the founding of the first porcelain factory in 1890, the town became world famous for the Tridelta-Bell and the development and manufacturing of electrical porcelain for insulators. Today, the Tridelta Campus Hermsdorf e.V. promotes cooperations, economy and science at the Hermsdorf hightech-location.
