Closed-die forgings
For more than 200 years, our plant has stood for the highest precision and quality in the manufacture of tailor-made closed-die forgings.
At Schmiedag we produce components from 5 kg to over 750 kg and, on request, deliver them pre-machined or finish-machined as ready-to-install components. At the Wildau site, we forge components up to 3.5 t.
Our forgings are used in large engines, railway technology, commercial vehicles and mechanical engineering, as well as in safety-critical applications and the defence sector.
With an in-house tool and die shop, high-performance forging hammers (160–630 kNm) and presses (31.5 and 45 MN), together with in-house quenching and tempering and extensive CNC machining capabilities, we provide the complete value chain from a single source: flexible, precise and reliable.

Scope of Services
Our production combines many years of forging experience with state-of-the-art technology to deliver tailor-made solutions at the highest quality level:
- Closed-die forging from 5–3500 kg component weight: production and machining of complex forgings in the medium to heavy segment.
- In-house tool and die making with 3D CAD/CAM systems: internal toolmaking with CAD/CAM and forming simulation for precise, repeatable results.
- CNC machining and heat treatment: machining on CNC lathes, CNC machining centres and HSC milling machines; in-house quenching and tempering and a metallographic laboratory for targeted material properties.
- Hardness testing and materials testing: Brinell, Vickers and Rockwell hardness testing; mechanical-technological testing in the scope of tensile and impact tests.
- Non-destructive testing and quality assurance: crack detection and ultrasonic testing of forged parts with modern test equipment for safety-relevant components.
- Assembly and surface treatment: painting and assembly lines for producing ready-to-install forged components.
