History

The building complex which was extended in 2019, provides more production and office space.

2019
Thanks to the continuous increase in demand we need more machines, more employees and thus more space. It's time for annex no. 5: our new building provides 500 m² of production space on the ground floor and 700 m² of office space on the upper floor.
