From our beginnings as a small ironworks to becoming one of the most modern foundries in Europe – in its over 125-year history, COSWIG has constantly evolved as a company and redefined casting in the process.
Since 1892 traditional skills and craft have been fused with state-of-the-art technology at COSWIG. With passion, experience and a spirit of research we have redefined what can be done, overcome new challenges and impressed new customers.
Our high quality standards and discerning customers keep driving us forwards. Today we produce and develop tailor-made castings at our high-performance plant. We are a leading international supplier for the production of rolls and special components for wind turbines, industrial mills and printing presses.
But there is no time to sit back and admire our successes. We grow with our tasks and challenges. Then as now, COSWIG carries out research into innovative concepts so that we can keep making our products, processes and materials that little bit better. Join us on this journey into the future. Set us a challenge and tell us what you need!
