Innovation is the basis of our business model

No one buys closed die forgings just because of a supplier's forging tradition of more than 120 years.
But our innovative strength would not be possible without the experience of all the decades of our existence.



We have been producing closed die forgings at our Plettenberg site since 1898.

With this wealth of experience, with uncompromising customer focus and customer proximity, but especially through our culture of innovation, we have become a technologically leading manufacturer of closed die forgings.

We find forging solutions even for very complex geometries with extremely demanding materials.

Owner-managed with a flat hierarchy and
short decision-making paths, we secure your product advantages…
