1Technical design data and Machinery List
A) Technical design data
1.1 ProductThe machinery was designed for the production of high-quality MDF, using UF-/MUF-resin for a wide range of board thicknesses and formats.The process technology bases on the use of a ContiRoll-press.All boards are sanded and are suitable for the use in the furniture industry or serve general purposes (e.g. flooring, etc.).
1.2 Press design parametersNominal press length 18 000 mmPress width 2 510 mm
1.3 Board sizeRaw board width approx. 2 510 mmNominal board width approx. 2 440 (8 ft) mmNominal board length approx. 5 520 (18 ft) mm mechanical design speed min. 20 mm/s
max. 500 mm/sFinished board formats
