Project teams from Voith and Sun Paper celebrate the successful start-up of Yanzhou PM 47. The new machine has the production capacity to produce 700,000 tonnes per year of packaging paper.
Sept. 20, 2026 - Voith has successfully started up PM 47, a new packaging paper machine supplied to Sun Paper at its Yanzhou production site in Shandong Province, China. With a wire width of 8.66 meters and an annual design capacity of 700,000 tons, PM 47 achieved its maximum operating speed of 1,400 m/min only 10 days after start-up, making it among the fastest-running multi-fourdrinier packaging paper machines worldwide.
The project progressed from civil construction to first reel in just 11 months and 8 days, while ramping up to its maximum operating speed only 10 days after start-up.
"The PM 47 project has set a new record for wide, high-speed packaging paper machines of this type," said Ying Guangdong, Deputy General Manager and Chief Engineer, Sun Paper Co. "This success was driven by the strong collaboration between both teams, who worked in parallel shifts throughout installation and commissioning with around-the-clock responsiveness."
Voith delivered PM 47 as a full-line supplier. The scope of delivery included the OCC stock preparation system, the UKP virgin fiber system, wet-end process systems, the paper machine from head-box to reel, as well as automation and digitalization technologies.
A key component of the project is the OCC line, designed for a capacity of 2,200 tons per day. The system also features Voith's IntensaPulper, enabling reliable and efficient raw material processing under large-scale production conditions.
The production line is equipped with Voith's advanced automation and digital solutions, including MCS, QCS, OnCare.CM and MillOne, covering process control, quality management, condition monitoring and production data management.
In addition, permanent magnet motor technology has been extensively applied throughout the stock preparation process, helping reduce energy consumption and further improve operational efficiency.
Following installation of the final equipment, the machine successfully produced paper only four days later, demonstrating the effectiveness of the commissioning process and the close collaboration between both teams.
After start-up, PM 47 reached an operating speed of 1,300 m/min within the first week and increased to 1,400 m/min after only 10 days.
The Group Division Voith Paper is part of the Voith Group. As the full-line supplier to the paper industry, it provides a large range of technologies, services and products and offers paper manufacturers holistic solutions from one source.
