“Whatever you choose, do it the best way you can”

We aim to meet the customers’ specific requirements perfectly. That is why, true to this philosophy, we began more than thirty years ago to treat workpieces and components made of a variety of materials with a thermal and thermochemical heat process. Even today this is exactly our expertise. Several proven methods, a modern computer-controlled infrastructure, an efficient laboratory, our consulting expertise and of course the decades of experience of PYRODUR AG are always available.

We look forward to solving your challenges.
