Overview

KÜSTER Holding GmbH (stylised KÜSTER) is a German, family-owned automotive supplier headquartered at Am Bahnhof 13 in Ehringshausen, Hesse. Founded in 1926, the company describes itself as a global family business with a tradition as a supplier to the automotive industry, and it positions its products as contributing to safer, more convenient, more environmentally friendly and more intuitive mobility. Its entrepreneurial principle is sustainability understood as long-term thinking rather than the short-term pursuit of profit. KÜSTER operates as a full-service supplier, producing intelligent electro-mechanical actuation and adjustment systems, in-house developed electronics and actuating elements. Its product portfolio includes actuators, drive cables, shifting systems, cable solutions and door systems, with named offerings such as the multi-actuator family, D-Lift, flow-control actuators, camera modules, central door-system control units, door handles, axle decoupling, park-lock actuators, thermal-management valve blocks, electric charging flaps, gear-shift actuation, window lifters and steering-column switches. It serves both passenger-car and commercial-vehicle applications. The group states that it is the global partner of almost all well-known automobile manufacturers, supported by customer-oriented action and reliable partnerships with strategic suppliers. Quality management is preventive and aligned with IATF 16949, with regular internal audits; the company cites numerous customer awards, including the Volkswagen Group Award, the MAN Truck & Bus Supplier Award and the Porsche Supplier Award. According to German Wikipedia, the family business founded in 1926 employed more than 3,000 people in 2016 across Germany, Slovakia, Mexico, Brazil, the United States and China — around 1,000 of them in Germany — and generated revenue of roughly 510 million euros in that financial year. The company develops and manufactures shifting and door systems, actuator technology, drive cables and drives for automotive manufacturers and suppliers. It remains in the ownership of the Küster family and is not publicly listed.

History

KÜSTER was founded in 1926 as a family business. According to its own product-world site, it looks back on almost 100 years of company history and almost 90 years as an automotive supplier, describing itself as a reliable partner for moving solutions in the automotive sector. The company's roots are in Ehringshausen, Hesse, where the group is still headquartered today at Am Bahnhof 13. In its early decades the firm operated as W. H. Küster GmbH; German Wikipedia records that the tattoo pioneer Horst Streckenbach worked as a locksmith (Schlosser) at W. H. Küster GmbH from 24 June 1957 to 19 September 1959. Over the following decades the company developed into a specialist in mechanical and electro-mechanical vehicle components, particularly shifting systems, door systems, actuator technology and drive cables. By the 2010s KÜSTER had become an international group. German Wikipedia states that the family business founded in 1926 employed more than 3,000 people in 2016 in Germany, Slovakia, Mexico, Brazil, the United States and China — around 1,000 of them in Germany — and generated revenue of roughly 510 million euros in that financial year. The company develops and manufactures shifting and door systems, actuator technology, drive cables and drives for automotive manufacturers and suppliers. In the 2020s the group presents itself as KÜSTER Holding GmbH, a global family business and full-service supplier of intelligent electro-mechanical actuation and adjustment systems, in-house developed electronics and actuating elements. Its product-world site highlights the multi-actuator family as opening new possibilities for modern mobility solutions, alongside products such as D-Lift, flow-control actuators, camera modules, central door-system control units, park-lock actuators, thermal-management valve blocks and electric charging flaps. The company continues to emphasise long-term, sustainable entrepreneurship, preventive quality management in line with IATF 16949, and customer awards from Volkswagen Group, MAN Truck & Bus and Porsche.
