Our site in Mühlhausen will be one of the most modern production facilities in the Upper Palatinate. Thanks to the possibilities offered by industrial science, manufacturing innovation and digitalisation, we are treading innovative ground. And through optimised processes, we can constantly improve product availability, both nationally and internationally. Our processes are becoming more and more digital so that we can easily and quickly access all relevant information. Checking product availability online, finding out the delivery status and much more: that is standard in our production.
At DEHN, people are what matters most.
Anyone can build a factory and put machines inside it – it is people who make the difference. We consider it our duty to treat our customers, colleagues and resources with due respect. For a secure future together.
Customer Centricity is a very central element for us. It is about gearing ourselves to customers, to their wishes and needs. Thanks to the commitment of our employees, we can offer our customers optimal solutions and excellent service. We are close enough to our customers to know what they need. Our major task is and has always been to consolidate and expand the excellent relationship of trust we have with our customers, both in real life and digitally.
We greatly appreciate the trust placed in us and work hard to earn it every day.
We are already very well positioned in terms of our products and existing processes. Nevertheless, our aspiration is to become better all the time - the further development of products and, above all, the development of smart solutions is a challenge we embrace with enthusiasm.
We are not content to sit back and enjoy our success: We constantly re-evaluate our products and processes and develop solutions which enable us to identify customer needs, even in international growth markets, and respond to them as quickly as possible.
We bring all this together and are optimally equipped for the future.
Pioneering role / know‑how
Digital Finance Transformation
An agile approach is required today when it comes to meeting customer requirements and supporting growth.
Data-based analyses enable us to plan ahead and react quickly.
As the world becomes increasingly internationalised and digitalised, there is a growing need for fast and reliable information in order to plan ahead and react quickly - this also applies to the financial sector. Here digital and automated solutions open up new ways for us to efficiently organise processes, recommend courses of action and identify business potential. Our task is to actively make use of the opportunities presented by digital technologies and to reap their benefits, in short: to point out and pave the way to a successful future with all the digital means at our disposal.
Innovative ideas, clear structures, and a competent team where you can rely on each other: that is the basis of our daily work. We are always on the lookout for the most effective way of doing things, both internally and for our clients. At DEHN, people who share their expertise, understand markets and technology, and enjoy their work join forces – to create forward-looking solutions for our customers worldwide.
At the same time, ongoing digitalisation is changing our world radically and rapidly. For us, digitalisation is not just a technical tool to optimise processes - it is also about shaping the future in a sustainable way. Starting with our solutions and continuing with production, our cooperation right through to service and consultation: We have the best prerequisites to master future challenges in a self-determined manner.
