Our company history
After leaving his business-partner in a company founded on April 1, 1964, which produced mainly precision microscopes, on August 1, 1971 Hermann Cloessner founded the present company in the garage of his own house.
In the early years the company manufactured cutting and bending tools for the camera production, as well as devices for the optics industry. Later, milled aluminum parts for the aircraft industry were added. The production was relocated to a newly built manufacturing hall in 1973.
In 1986 the founder’s sons, Ulrich and Wolfgang Clößner, took over the company. By that time the company already had 16 employees. Four years later, with the dedication of the brand new company complex at Leuner Weg 14, the company was ready to expand production.
The production area was continuously expanded and adapted to meet requirements. Further new buildings and extensions followed in 1999, 2006 and 2009, as well as a new administration building in 2014.
Over the years, the product range grew and the company successfully achieved entry into the sectors of defence and medical technology as well as the semiconductor industry. Further processing technologies were established. Today, the company covers almost all machining processes. Parts from the family business can be found in the majority of passenger aircrafts worldwide – from small screws to complex large-scale aluminium components and assemblies.
In 2018, Mario Clößner took over the management, succeeding his father Ulrich Clößner.
In 2024, Toni Clößner followed, joining the management two years earlier than planned due to the sudden death of his father, Wolfgang Clößner.
The completion of another production hall in the neighbouring municipality is planned for 2026. Among other things, the company intends to relocate its training workshop to this hall, thereby freeing up space at its main site. This will provide approximately 5,000 square metres of production space in the future.
The company currently employs over 80 qualified employees.
