A vacuum molding process uses a flexible molding skin having an imprint face arranged inside an airtight compartment. Before the vacuum is made, a pasty plastic material is incorporated in the compartment facing the imprint The vacuum is then made in the compartment to press the flexible molding skin onto the plastic material with formation of a molded surface with sculptures and asperities giving a decorative or functional granular appearance. The molding skin is made of a flexible anti-adhesive organic material, notably silicone, for ease of removal from the mold after the plastic material has hardened Shaping of the panel is performed after the vacuum bag has been positioned on a shaping part. The process is used for manufacturing artificial climbing wall panels.
