In this study, we attempted to manufacture wood-based products of arbitrary shapes and high strengths by allowing the cryptomeria to flow and harden in a metal mold without using a binder. Experimental results show that the wood has good liquidity owing to the maintenance of its moisture using the metal mold that remains sealed in a hot press. The good product along the metal mold shape was obtained under the following processing conditions : a molding pressure of 60-160 MPa, a molding temperature of 140-180°C and a moisture content of 10-50%. Moreover, the molding pressure that can be molded decreases at a high temperature and a high moisture content. The density of the obtained good product is 1.36 g/cm3, and the average Vickers hardness is 29.4HV0.1. In addition, the product obtained at a molding temperature of 160°C and a sealing time of 90 min does not facilitate shape recovery even if it boils with water for 30 min.
