Customer: Sun Paper
Production: High-quality white folding boxboard
Description: Asian paper producer Sun Paper recently successfully started up PM2 at its site in Beihai in Southeast China. The new line in visionary industrial design now produces high-quality white folding boxboard with a basis weight of 170 to 350 gsm and a wire width of 8,900 mm. With a design speed of 1,400 m/min, the planned annual capacity is over 1 million tons of paper. Thanks to the very successful cooperation between Sun Paper and Voith, the entire project from initial contracting to start-up in December took only 18 months – a new world record for a high-speed line of this type. This is the third paper machine that Voith has started up for Sun Paper in the last 12 months. In total, Voith has already delivered 12 XcelLine paper machines to Sun Paper.
Details: As a full-line supplier, Voith supplied the entire XcelLine paper machine in the new industrial design. The tailor-made concept focuses on the efficiency and robustness of the individual components. For example, a DuoFormer ensures excellent formation and strength properties even at very high speeds. Automatic dewatering of the three shoe presses reduces thermal drying and thus saves significant energy costs. For an optimized paper surface, a SpeedSizer is used as well as four DynaCoaters, which apply the film evenly during sizing and coating. Furthermore, the CombiDuoRun dryer section with EvoDry steel dryer cylinder ensures maximum runnability and energy efficiency. In addition, two VariFlex high-performance winders ensure smooth production. Due to the visionary Voith industrial design of the entire line, optimized accessibility for maintenance work and improved occupational safety are also achieved.
Sun Paper also benefits from Voith’s leading expertise in digitalization and automation for additional efficiency gains and cost reductions. The intelligent quality control system QCS as well as the solutions DCS and MCS enable complete control over the entire production line. In addition, Sun Paper relies on solutions from the Papermaking 4.0 portfolio with OnCare.Health. Thanks to a wide range of interfaces, the intelligent maintenance tool detects the smallest faults at an early stage and automatically assigns them to the affected points.
