Voith commissions NipcoFlex shoe presses on Wanlida’s paper machines in China

Voith Paper, a unit of Voith Group, has installed and commissioned the new NipcoFlex shoe presses on the Wanlida Paper-Products’ BM 4 and BM 5 paper machines in China.

The shoe presses were installed as part of a contract awarded to Voith in August 2016. The contract scope includes supply of three NipcoFlex shoe presses as well as control systems for the second presses on the BM 3, BM 4, and BM 5 machines at Wanlida.

The BM 4 and BM 5 paper machines are equipped to manufacture testliner paper using filly domestic recycled paper with a basis weight of 120-200g/m2 and 6260mm of wire section width.

Upon completion of the upgrade, the machines’ operating speed has been increased by 50% to 80m/min while the dryness of the paper out of the press section increased from 45% to over 50%.

Additionally, the steam consumption and paper breaks of the two machines were reduced while the sheet strength was improved considerably.

Wanlida Paper-Products official said: “We are very satisfied with the overall performance of the machines following the shoe press upgrade, which has brought us tangible and notable benefits in terms of improved dryness, reduced energy consumption, lowered operating and maintenance costs, and improved operational efficiency.”

Voith said it would soon commence work on installing the shoe press on the BM 3 machine for Wanlida.

A Sino-foreign joint venture, Wanlida Paper Products is engaged in manufacturing kraft, liner, and high-strength corrugated paper in China.
