PANEL FORMING

There is disclosed a method for producing a panel (1) with a wood based core (3) and a surface layer (2) comprising a powder based layer， wherein the powder comprises wood fibres and a thermosetting resin. The method comprises the step of curing and connecting the surface layer (2) to the core (3) while applying heat and pressure in a first main pressing step， thus raising a temperature of the surface layer above an initial temperature. The method also comprises the steps of applying a bending force (F) on the panel (1) after the first main pressing step to bend the panel such that an uppermost surface of the panel is convex and a lowermost surface of the panel is concave while the panel is still above the initial temperature， and releasing the bending force such that the panel springs back to an essentially flat shape.
