What is the MDF Forming Station?
For the production of MDF (Medium Density Fiber), HDF (High Density Fiber),
THDF (Thin HDF) and insulation boards, the Dieffenbacher fiber board forming
station stands for the forming of an accurate and homogeneous mat
for highest quality standards.
Due to a special discharge and dissolving system combined with the
adapted spreading head type and the following controlled scalping and
weighting systems, the endless mat is formed with a high weight accuracy
cross- and lengthwise over a large range of all thicknesses.

Your benefits
Integrated fiber lump dissolving in the bin discharge
Optimized utilization of material due to reduced scalping and
direct return of material to the bin
Universal forming concept from ultra thin (1 mm) to thick boards (40 mm)
High process stability due tot large capacity forming bin
High surface quality mat suitable for all kinds of mechanical processing, laminating
or direct and digital printing
Low energy consumption concept (no vacuum system and high efficiency drives)
Controlled weight distribution cross- and lengthwise for high forming accuracy
Highest weight accuracy due to integrated mat profiler for thin board production
