KOLBUS. Foundry – since 1877

Cast Foundry apprentice KOLBUS

We are experts in ferrous-based casting, producing high quality castings for customers in a wide range of industries for over 125 years. We'll cast anything from single pieces to small production runs and with 60 employees, we can offer you expertise and all-round support.

Demand for the technically challenging castings produced in the KOLBUS foundry comes mainly from the engineering and heavy engineering industries. We apply our long-term experience and wide-ranging know-how to developing custom solutions for our customers. Production capacity of ›good castings‹ is 3,500 t per year. 20% of foundry production is used in-house in KOLBUS machines; 80% are custom castings for a wide variety of industries. 

We maintain a stock of 11,500 models which are immediately available.
