Valmet – OptiCalender Metal Belt
OptiCalander Metal Belt introduces a completely new method of making board. The metal belt calender simplifies the entire board-making process and releases drying capacity by removing the speed limits caused by Yankee cylinders. This results in extremely high bulk and stiffness, together with very smooth surfaces.
Valmet – Aqua cooling calendering
Valmet's new, patented technology offers better calendering results than normal production conditions. Aqua cooling calendering enables the production of lighter-weight end products – without compromising on functional and visual properties. This will lead to substantial reductions in energy use and raw materials.
Valmet calendering pilot facilities
Valmet’s calendering pilot facilities offer the latest technologies and innovations in its field, such as aqua cooling calendering and metal belt calendering. The facilities allow you to run tests on a set up which mirrors that, which you have at your facilities, or alternatively the type of configuration you are looking to set up.
Valmet OptiConcept M - Completely new way to design, build and operate a paper machine
Valmet’s focus is on supplying smart papermaking lines with sustainable solutions. OptiConcept M is a modular concept that makes a difference. OptiConcept M family, launched in 2011, suits coantainerboard, cartonboard and fine paper production – simple, well-functioning solutions that meet customers’ needs.
Zhuhai success story with Valmet’s metal belt calender
In 2007, Zhuhai S.E.Z. Hongta, located in China, added a new ValZone metal belt calender into their folding boxboard BM 2 . Today the calender is renamed into OptiCalender Metal Belt. The investment resulted in better board surface quality and higher bulk, and thus begun the lightweighting trend in China as well.
