ZONGULDAK, TURKEY / HEIDENHEIM, GERMANY. Voith, Modern Karton and Harbin Electric International Company Limited (HEI) are celebrating the successful start-up of the new high-speed XcelLine PM 6 and the associated BlueLine stock preparation plant at the Zonguldak site in Turkey. The plant will produce up to 640,000 metric tons of recycled containerboard annually, thereby increasing Modern Karton's total production capacity to almost two million metric tons per year. This will consolidate the position of Modern Karton as one of the leading manufacturers of packaging papers in Turkey and one of the largest in Europe.
The success of this project demonstrates the long-standing and trusting cooperation between Voith and Modern Karton. The collaboration with HEI, which was commissioned by Modern Karton for project execution, was also based on partnership and trust.
The scope of supply for the PM 6 includes Voith's broad full-line portfolio, including the BlueLine stock preparation system with approach flow system, the XcelLine paper machine, a VariFlex Performance winder with SmoothRun vibration damping and TwinDrive double unwinding. Voith's subsidiary Meri supplied a complete reject and sludge handling system.
Comprehensive automation solutions such as the OnQuality quality control system, the OnCare.Health condition monitoring system, and OnControl MCS and DCS are also part of the new equipment for PM 6. Complete Papermaking 4.0 solutions, including the IIoT platform OnCumulus, the digital process control OnEfficiency.Strength and the maintenance management tool OnCare.Asset round out the scope of supply and provide Modern Karton with state-of-the-art digital technologies for maximum production efficiency.
