New milestone reached for Dieffenbacher as CPS+ Press produces first board

Dieffenbacher CPS+ press in operation

17 months after Dieffenbacher unveiled the new continuous CPS+ press at LIGNA 2015, the first plant with a CPS+ press is now successfully into operation at Kronospan’s new particleboard plant in Bjelovar, Croatia. After a seven-month assembly period, the first board was born on October 1, 2016.

“The process of commissioning the first CPS+ was seamless,” said Bernd Bielfeldt, Dieffenbacher head of the Wood Business Unit.

He added that Kronospan was satisfied and that working together on the project proved to be very successful. After two weeks, Koronospan increased production to three shifts.

Dieffenbacher began development of the new generation of presses in 2014. The goal was to improve the thickness tolerances of manufactured boards. Due to the modular frame with its new arrangement of press cylinders, the CPS+ ensures evenly distributed pressure. This means consistently high product quality and low raw material consumption.

“We are confident that Kronospan and other customers will benefit from the advanced CPS+ technology,” explained Bielfeldt. For example, new thermoactive roll plates ensure that the mats can be heated at an earlier stage. The CPS+ Press also offers improved accessibility for servicing. Its clear distinction between the supply side and the maintenance side enables faster and more convenient press maintenance.

The CPS+ has all the advantages of the original CPS model, proven over decades of service. These advantages include the variable double joint press infeed, thermal expansion of the frames—which allow product changeover on the fly without interruptions—and the Parallel Press Gap System (PPS), which stops the mat “breathing out” between the cylinder banks.

Dieffenbacher has since sold 11 CPS+ presses. Two are in Thailand and commissioning of the first board will take place in the first half of 2017.
