A method for the manufacture of molded wooden products by the deep-drawing of wood fibers is provided . The wood fibers to which a synthetic resin-containing binder has been added are introduced into a mold directly or after being formed into an unmatted mass. The shaping mold is divided into plural parts so that either the deep-drawing part or the remaining part is first closed to press firmly the fibrous mass to such an extent the fibers cannot move, and then the entire mold is used for the compression molding of the fibrous mass into a molded wooden product.
