The world's largest cartonboard machine, Ningbo Asia Pulp & Paper's PM 6, located close to the city of Ningbo in China's Zhejiang province, has once again reached new production and speed records. On 22 November 2006 the machine produced 2,823 tons/day of folding boxboard, which is more than any other paper or board machine has ever produced. This record is a result of continuous work and co-operation between the Ningbo mill and Metso Paper.

In December 2006, the machine made a record monthly production of 69,693 tons, thus exceeding its design capacity with more than 10,000 tons. In 2006, the annual production of PM 6 amounted to a tremendous 733,500 t/a – a significant increase to the line's original design capacity of 700,000 t/a.

Also, yet another speed record of 854 m/min in the basis weight of 250 gsm was made on 12 January 2007.


Said Chen Hsingliang, Vice President of Ningbo APP: "These records are great milestones for both Ningbo Asia Pulp & Paper and Metso Paper, made possible thanks to the good co-operation between the two companies."

The 410-m-long Ningbo Xiaogang PM 6, which was started up in November 2004, is designed to produce high-quality Duplex and Triplex grades of white lined chipboard (WLC) in a basis weight range of 250 to 450 gsm. It can also successfully produce folding boxboard (FBB). The line has a trim width of 8.1 m and a design speed of 900 m/min. Supplied by Metso Paper, the line consists of a complete eight-line stock preparation system for both virgin and recycled fiber, and a complete five-ply board machine including five-station on-line coater.
