METHOD OF PRODUCING A 3D MOLDED PULP PRODUCT

The present disclosure provides a method of producing a 3D molded product from a pulp slurry. The method comprises applying a pulp slurry layer to a porous forming face of a first mold， in a first forming step， pressing the pulp slurry layer against the porous forming face of the first mold， while heating the pulp slurry layer and drawing a vacuum through the porous forming face of the first mold， transferring the pulp slurry layer to a porous forming face of a second mold， in a second， subsequent， forming step， pressing the pulp slurry layer against the porous forming face of the second mold， while heating the pulp slurry layer and drawing a vacuum through the porous forming face of the second mold. In the method， a first pressure at the rear side of the forming face of the porous forming face of the first mold is lower than a second pressure at the rear side of the porous forming face of the second mold.
