OUR IRON FOUNDRY
Perfection since 1902
Heger is a leading company in the foundry industry in the field of iron casting. Today, we supply our castings all over the world, not just in Germany.
At our production site, we cover a broad spectrum in terms of quantities and unit weights. With a passion for foundry technology and a high level of innovation, we are the market leader in Germany in the field of large cast parts for wind turbines.
Our specialization: Serial production of large castings from 5 tons
We specialize in serial production of heavy components with unit weights from 5 tons. State-of-the-art production technologies, extensive process expertise and the highest quality standards enable us to provide customized solutions – from smaller parts to large components weighing 32 tons.
Today, we supply our castings all over the world, not just in Germany.

All services from a single source
We offer the complete process chain from consulting to the finished component:
- Technical advice and casting design
- Development of complex castings
- Support during the prototype phase
- Simulation of strength verification, solidification and cooling
- Series production with maximum repeatability.
Material innovation – actively shaping progress
We are heavily involved in materials development. Our employees are actively involved in industry association activities as well as in special research committees and projects.
The new material group of “solid solution strengthened GJS” grades included in DIN ISO is a good example of the successful commitment of our experts. This “third generation” cast iron represents a milestone in our industry. The rapid implementation in practice is proof of the technological maturity of our family business.
Built for the future. Made in Germany.
