Method for manufacturing form-pressed wood fibre panels, for example door skins, and panels manufactured according to the method. The process starts from a workable, mass produced panel displaying high thermal conductance, for example a so-called MDF-board or chip board. The panel is preheated to a condition where the wood fibres and the binding agent which binds the wood fibres form a pliable or stretchable composition though still in continous panel-like condition. This preheated panel is fed to a form-pressing device where the pressure is relatively slowly increased from 0 to approximately 30 kg/cm<2> during continuing heat supply to a temperature of around 150-200 DEG C. Usually this is attained in connection with door skins after a period of approximately 1,5 minutes. Finally, a form-stable, form-pressed panel is removed from the press. |
