Constant pressing force
In order to achieve a clean pressing pattern, a uniform pressing force must be ensured when pressing the board assemblies. The hydraulic system plays an important role in this. The Kallfass hydraulic concept is based on quasi-isobaric pressing that enables the generation of both vertical and transverse pressure. Pressure control ensures a constant pressing force of 1N/mm² over the entire board surface, even where a maximum board width of 3.6 m is involved.
