In 2014, Hansol Daejeon rebuilt its PM 31 board machine with OptiDry Coat air drying technology. Thanks to the excellent results, Hansol decided to perform a similar upgrade on its PM 32 board machine in 2015. Besides energy savings, Hansol has also seen improvements on their FBB quality; printability is good and
visual appearance has improved. Furthermore, runnability has improved and the “folding” effect reduced.
The PM 32 order was an easy decision for Hansol. Valmet had performed very well and even exceeded the performance targets for the PM 31 delivery.
