Family Business with
Tradition & Innovation
Your German partner for automation and digitalization in surface technology for over 30 years. With hands-on mentality and passion.
A Story Written by People
It all began in 1989 with an idea: Dierk Langer (Electrical Engineering) and Dr. Siegfried Kahlich (Physics) wanted to rethink electroplating control – with the simple, bold statement: "This can be done better." Together with customers, this became practice step by step. In 1995, DiTEC Dr. Kahlich & Langer GmbH was founded.
What sustains us to this day is not just solutions and over 1,000 installations – but above all the people behind them: a team of motivated, dedicated employees who think along, get things done and stick together. Young and experienced work hand in hand with us, in a family atmosphere that is open to new ideas.
And that is exactly how it continues: With fresh wind from the next generation. The founder's son brings new perspectives, tackles future topics and leads DiTEC into the next phase with great energy – so that we remain a partner you can count on in the long term.
Our drive remains the same: team spirit, passion and the commitment to apply modern technologies in practice – and working with genuine joy to ensure our customers are successful.

Management
"Our goal was never just to deliver software. It was always about creating solutions that make the industry more efficient and sustainable. But equally important to us was the trusting and appreciative collaboration with our customers. That this has resulted in 30 years of shared success, trust and many valuable encounters fills me with great gratitude. And one thing is clear: without our motivated team, none of this would have been possible."
Dr. Siegfried Kahlich
Managing Director
"I am proud to follow in my father's footsteps and usher in the next generation at DiTEC. For me, this means: continuing what has proven itself with respect while having the courage to initiate new things. My goal is to make our family business future-proof not just for today, but for the next 30 years, while living up to our claim as technology leader."
