<p>Plastic fibers and plant fiber such as thinned woods, scrap woods of buildings, stumps, branches or barks are stirred and mixed with each other into a felt-like material. Microwaves are radiated on the felt-like fiber mixture material. After a sufficient temperature is ensured for the felt-like fiber mixture material of low density by the microwave radiation, the fiber mixture material is fed to a pair of upper and lower pressure plates and compressed thereat. The fiber mixture material is rapidly compressed by the pressure plates so as to be melted and integrated. Then, the fiber mixture material is cooled so as to be further packed by such cooling, thereby becoming a stronger plastic fiber board.</p> |
