Abstract

The invention relates to a method (100) for manufacturing molded parts (10) from biodegradable fiber material (11) by means of a fiber molding process in a fiber molding system (20), comprising the following steps of providing (110) a pulp (1) as a liquid solution containing a biodegradable fiber material; contacting (120) a suction tool (2) with the pulp by placing it on or at least partially dipping it into the pulp, wherein the suction tool comprises a suction head (21) with a three-dimensionally shaped suction head suction side (21i), whose shape is adapted to a contour of the subsequent molded part; molding (130) the molded part by sucking the fiber material onto the suction head suction side (21i) by means of negative pressure in the suction tool; pre-pressing (140) the molded part in a pre-pressing station (3) with a pre-pressing pressure (VD) to reduce a proportion of the liquid solution in the molded part; hot-pressing (150) the pre-pressed molding at a hot-pressing pressure (HD) for finishing the molded part and for further reducing the proportion of the liquid solution in the molded part in a hot-pressing station (4); and outputting (160) the finished molded part (10). The invention also relates to such a fiber molding system for carrying out the above-mentioned method and to a molded part manufactured by means of such a fiber molding system or by means of such a method.
