We'll cast anything from single pieces to small production runs and we can offer you the expertise and all-round support of 60 highly skilled employees committed to delivering quality for our customers.

We are pleased to announce that we have an impressive production capacity of 3,500 tonnes per year. This allows us to meet the demands of a wide range of industries and customers who require high-quality castings for their products. We take pride in offering custom solutions tailored to each client's specific needs, with 80% of our production dedicated to these bespoke castings.


From simulation to optimised casting

Our iron casting specialists will help you with design decisions, material selection, component design for casting, and during development with casting and solidification simulations.


Casting database

An advanced production tracking system precisely coordinates the progress of every component, resulting in highly transparent and cost-effective processes. With the help of the KOLBUS casting database, our ERP system, an in-house development of the existing software, visualises the entire production process. We would be pleased to talk to you about quality management, and our production and offer you an insight into modern mechanical engineering.
