Outstanding casting quality is just the beginning. At Cotarko, we rely on highly automated machining centers to achieve maximum efficiency and quality.
Our high-performance machinery, consisting of systems from Ex-Cell-O, Felsomat and MAG Specht 500, covers all customer requirements. Integrated component assembly rounds off our production spectrum perfectly.
Everything from a single source: from raw casting to finished component
By integrating mechanical processing & assembly, we minimize interface losses and shorten your supply chains. Our range of services includes
-
CNC machining: High-precision milling, drilling and thread cutting on machining centers.
-
Leak test: Integrated tests to ensure functionality, especially for housing components (inverter/gearbox).
-
Component assembly: On request, we can supply not only individual parts, but also fully assembled units including purchased parts.
