What else should you know about us?

Company Culture

For us, entrepreneurial success is inextricably linked to social responsibility. Accordingly, we organise family-friendly working conditions, train young people and employ refugees and the long-term unemployed.

We are a classic medium-sized company: simple structures, flat hierarchies, great flexibility. Our daily actions are based on our guideline "Control is good, trust is better". This, of course, requires good and committed employees who show a high sense of responsibility. That is why we rely on open-ended contracts, individual working time models and waiving temporary workers.


We offer our employees numerous leisure activities, e.g. Christmas and summer parties, football tournaments or company runs, thus promoting cohesion among the employees of the two companies and the different departments. In 2022, our company team took 2rd place at the Union Sponsors Cup (football tournament).


Our in-house canteen offers our employees daily breakfast and lunch and is used for catering our guests and for special occasions such as company celebrations, anniversaries or birthday celebrations.

Apprentice workshop

We are training young professionals ourselves for many years – especially machining mechanics, tool mechanics and industrial clerks. It is important to us to provide young people with the knowledge they need to carry out their profession well. This way we also ensure to win competent and motivated junior employees for ourselves, thus coping with skills shortage.

The practical part of the training takes place in our apprentice workshop and the apprentices can apply their new knowledge in everyday production right away.

Social commitment

We are sponsor of the neighbouring football club 1. FC Union Berlin and the rowing club Friedrichhagen (Friedrichhagener Ruderverein). Since 2022 we are also sponsor of FaSTTUBe - Formula Student Team of TU Berlin. We also support other local associations that are particularly important to our employees.  

We are also a founding member of the non-profit association “Türöffner e.V.”, which advocates the entry of refugees into the labour market.

In addition, we are a member of the foundation "Remembrance, Responsibility and Future" of the German industry, which testifies to the political and moral responsibility of the state, economy and society for the Nazi injustice.
