The cooperation between the Model Group and Hunkeler Systeme AG has lasted 35 years. The partnership is characterized by mutual trust, high quality awareness and shared values.
Almost two years ago, Model AG in Weinfelden put a new baler into operation. It was another milestone in what has now been three and a half decades of successful cooperation with Hunkeler Systeme AG. The baler is the final element of a large-scale disposal system that ensures a continuous process in corrugated cardboard production in 24/7 operation. With 120 tons of press force, it is the largest of its kind to date in a production plant in Switzerland. The force is built up via two powerful electric motors. For each motor, a frequency converter activates the drive as soon as a defined filling level is reached in the shaft. The energy savings compared to the predecessor press, whose motors were always active, are significant, says Thomas Weibel, who manages investment projects at Model.
