Advanced foundry technology
Castings from the KOLBUS. Foundry
Castings from prototypes
We are experts in ferrous-based casting, producinghigh quality castings for customers in a wide range of industries for over 200 years. We'll cast anythingfrom single pieces to small production runs and wecan offer you the expertise and all-round support of60 highly skilled employees committed to deliveringquality for our customers.
Demand for the technically challenging castings producedin the KOLBUS foundry comes mainly from the engineeringand heavy engineering industries. We apply our in-depthexperience and wide know-how to developing custom solutions for our customers. Production capacity of ›goodcastings‹ is 3,500 t per year. 20% of foundry production is used in our own KOLBUS machines; 80% are customcastings for other industrial customers.
We maintain a stock of 11,500 moulds available immediately on demand.
