Blech plus Götz von Berlichingen

The Iron Hand'
The region's


Around 1530,

Götz von Berlichingen had his famous iron hand produced. For its time, it is an absolute masterpiece of sheet-metal machining and engineering. Götz lost his hand in 1504 in the War of the Succession of Landshut. The knight Götz von Berlichingen became famous far and wide through his Swabian greeting "Legg me am Arsch" ["kiss my xxxx"], and also the play "Götz von Berlichingen" from Johann Wolfgang von Goethe. This can be experienced in the annual castle festival, which has been taking place since 1949: Burgfestspiele in Jagsthausen.


LTI-Metalltechnik is one of the leading companies in supplying complex sheet-metal parts of a wide variety of types. Over 700 employees work on a production area of 36,600 sqm at the four locations Berlichingen, Bobstadt and Windischbuch (plants I and II). The sister companies in Thuringia and the UK altogether employ some 260 members of staff and have a combined production area of around 11,500 sqm (England and Thuringia).


On 1 August 1969, Klaus Isaak founds LTI-Lüftungstechnik as a one-man-enterprise in Berlichingen. This step towards independence starts the 50-year success story of LTI-Metalltechnik which runs to today.


The one-man business becomes a limited company with 6 employees. The products of LTI-Lüftungstechnik originate from agriculture. With hay blowers and thermal pumps for heating up process water through barn air, LTI was already developing highly innovative and forward-thinking products back then.


The foundation stone for the new production facility is laid in the industrial zone in Berlichingen. The first punching machine from the company Trumpf is put into operation. 40 employees are producing relatively simple sheet-metal parts on 1,250 sqm.


Due to the falling demand for agricultural products and the simultaneously rising demand for sheet-metal parts, Klaus Isaak founds BVG Blechverarbeitungs GmbH.


LTI-Lüftungstechnik GmbH renamed to LTI-Metalltechnik GmbH. At the same time, Klaus Isaak together with other notable companies from the ventilation sector found a new company with the name LTI-Lüftungstechnik. This company was taken over by the company Systemair in 1999.


The training centre for LTI Youngsters is opened. On 2,100 sqm, our trainees manage their 'own small company', thus securing the future of LTI as exceptionally well-trained junior employees.


The sister company LTI-Metalltechnik Pößneck GmbH is founded in Thuringia. Thanks to having a similar production range to LTI-Metalltechnik in Berlichingen,

both companies benefit from exchanging capacity and associated synergy effects.


Founding of the subsidiary company LTI Metaltech Ltd. in Abingdon, UK. Products are produced exclusively for medical technology on an initial 2,000 sqm.


Once all expansion options at the headquarters in Berlichingen have been exhausted, a modern production hall appears in Boxberg-Windesbuch, with a coating and logistics centre. This location has been expanded to its current size today of 20,000 sqm through additional construction stages.


Together with the company founder Klaus Isaak, Frank Isaak (left) and Markus Kaiser (right) form the company's executive management, henceforth guiding the destiny of LTI as a threesome.


Takeover of the company SUBCON Production GmbH in Boxberg-Windischbuch. The machining manufacturing of LTI is expanded by 1,900 sqm through this takeover.


The company's 40-year jubilee is celebrated together with customers, suppliers, companions and above all with the employees.


Constant expansion of welding proficiency through investment in new welding practices. Altogether there are now three laser-welding systems, three solid-state lasers and seven welding robots.


Construction of a state-of-the-art logistics centre began at the location in Boxberg-Windischbuch in November.
