Abstract
A method for manufacturing a mold using seaweed pulp according to an embodiment of the present invention comprises: a step for filling the inside of a storage device with a pulp liquid containing seaweed pulp formed from a seaweed raw material; a step for measuring the moisture content of the pulp liquid in the storage device; a step for adjusting the moisture content of the pulp liquid to fall within a preset range when the measured moisture content is outside the preset range; a step for filling a mold of a molding apparatus with the pulp liquid having the adjusted moisture content; and a step for producing a molded product in a shape corresponding to the mold by applying pressure to the pulp liquid in the mold.
