Valmet's Cutting-Edge Hard Nip Sizing Technology in Board Production

In a significant development for the paper and packaging industry, Valmet has announced its latest investment in hard nip sizing technology, aimed at enhancing the strength properties of board made at one of its European customer’s facilities. This advanced technology not only boosts the performance of board machines but also aligns with the industry's increasing focus on sustainability and resource efficiency.

The Need for Stronger and More Efficient Boards

Recent trends in consumer preferences demand lighter, yet stronger boards without compromising quality. Manufacturers are constantly working to improve their processes and reduce raw material consumption. Recognizing this industry challenge, Valmet has positioned itself as a leader by offering innovative technological solutions that optimize production.

Valmet's hard nip sizer operates on the principle of applying starch using high-pressure rolls, a method that is distinct from traditional techniques. This innovation allows for significant reductions in starch consumption while ensuring that the strength and integrity of the board are maintained.

How Hard Nip Sizing Works

The technology incorporates hard rolls equipped with spray nozzles that meticulously apply starch to the board at high pressure. This process helps in infusing the starch deeper into the web material, effectively enhancing the board's strength. By utilizing this method, manufacturers can create boards that are lighter yet possess improved physical strength, meeting the evolving demands of the market without excessive use of materials.

Klaus Kiviniemi, Valmet's Product Sales Manager for Sizers and Coaters, remarked, "Hard nip sizing technology offers a robust solution for modern board machines. It combines superior strength development with notable starch savings, supporting the industry trend towards greater sustainability."

Commitment to Sustainability

Valmet is not just focused on technological advancement but is also committed to promoting sustainable practices within the manufacturing sector. The company aims to help its customers transition towards more regenerative production methods while minimizing waste and resource use. This commitment is palpable in the delivery that includes not only the hard nip sizer but also complementary supply systems along with spare parts and consumables packages.

This investment underscores Valmet's strategic mission of guiding its customer industries toward a promising future, emphasizing efficient resource utilization through advanced technological services. As part of this initiative, the successful start-up of the new system is scheduled for spring 2027, which marks a significant step forward in achieving greater operational efficiencies.

Valmet's Industry Leadership

With a legacy of over 225 years in the industry, Valmet has established itself as a global technology leader serving various process industries. The company employs approximately 18,500 professionals and operates in about 40 countries, promising to deliver innovative solutions tailored to customer needs.
