Abstract. Conventional injection cannot adequately fill wood powder in the mold due to the intergranular friction. To solve these problems, we proposed an injection compression molding technique for wood powder with a natural binder composed of sucrose and citric acid. The effect of the additional pressure from the rear on the moldability and the mechanical properties of the molded product was investigated. By applying pressure from the rear, the molded product became darker in appearance, and its density increased by approximately 20%, approaching the true density of wood. Furthermore, its hardness reached a level comparable to that of polyvinyl chloride (PVC). This result indicated that the rear pressure is effective in improving the moldability and mechanical properties of the molded product.
