Using a metal mold 20a composed of the convex frame member 21a and the concave frame member 22a, between the convex frame member 21a and the concave frame member 22a, it is sandwiched between a pair of covering films 12. The molding raw material 14 is placed, the mold is tightened, and then the raw material for molding and the coating film 12 are heated to steam foam the biodegradable molded product, and the coating film 12 is softened to biodegrade. The surface of the molded foam molding is pressed.n n n Thereby, a method and a molding mold for producing a biodegradable molding that can easily and accurately produce a biodegradable molding having sufficient strength even in a complicated shape and having sufficient water resistance, good biodegradability and excellent surface smoothness. Can be provided. |
