Heat treatment, by tradition

Iron ore has been processed and smelted in the Siegerland area for over 2,500 years, meaning heat treatment has a long tradition in our region. We trust in the experience gained from thousands of years of tradition. We are always learning more, allowing us to create new things with passion based on proven expertise. Today, our company has over 40 years of experience in the industry.

Heat treatment production processes

Heat treatment today uses new technologies wholly unlike those of 2,000 years ago. Part of our founding history at Demig is making your production processes and documentation easier. Just like the people in our region, we have learned to take advantage of every opportunity and to make things better and easier. 

We look far into the future, and we are always discovering new possibilities that are durable and resilient, and that function reliably over a long period of time. We rely on these technologies, an approach we consider innovative. If you believe sustainability means value stability, then you have come to the right place.
