PM 71, supplied by Voith, was developed for a speed of 1,300 meters per minute and a wire width of 9,300 millimeters. It produces up to 350,000 tons of lightweight corrugating medium per year.
Oct. 30, 2025 - Voith announced the successful start-up of PM 71 at Shanying Suzhou Paper in Suzhou, west of Shanghai, China. PM 71 compliments the recently started-up sister machine at the mill, PM 72 — another Voith-supplied paper machine.
According to Voith, PM 71 was developed for a speed of 1,300 meters per minute and a wire width of 9,300 millimeters. It produces up to 350,000 tons of lightweight corrugating medium per year with basis weights ranging from 50 to 90 g/m2.
Together, PM 71 and PM 72 will be capable of producing up to 800,000 tons of corrugating medium in the basis weight range of 50 to 120 g/m2.
The PM 71 project features technology from Voith's XcelLine including a MasterJet Pro headbox, DuoFormer D II and DuoCentri NipcoFlex shoe press. The hybrid former concept ensures consistent paper quality and low energy consumption even at high speeds. Single-tier dryer sections in the pre-dryer and after-dryer section increase runability. The system is complemented by a SpeedSizer AT film press and MasterReel reeler.
Digital systems such as DCS, QCS and OnCare.Health ensure efficiency, quality and low operating costs.
Voith pointed out that many components for PM 71 were manufactured locally, enabling faster delivery and installation.
"The teams from Voith and Shanying worked closely and professionally together," explained Hao Mingjin, Production Manager at Shanying Suzhou.
Voith noted that shortly after commissioning, PM 71 met the partners' expectations — stable production conditions with consistent cross-profiles and high-quality finished paper rolls.
