The superposed wet green layer is molded by hot mold pressing and drying. The molding machine used in the manufacturing is a modification of the existing pulp molding machine. That is, the feed pipe is a feed pipe group that communicates with different pulps, and the hot press mold base has a pressure water pipe. To solve the single-layer products can not achieve the effect: as long as placed in a certain layer of oil, insulation, antibacterial, waterproof, heat insulation, vibration absorption and other additives or pigments, the products can have a corresponding function or appearance and there are Low cost and excellent effect.
