PURPOSE:To obtain a skin body providing a thin skin only at necessary parts and free from material loss by a method wherein only necessary parts of a force in heated up to the melting temperature of powdery molding material, and compressed air is ejected into the force to remove antigelling molding material. CONSTITUTION:Temperature ragulating pipes 11 are stuck only to necessary parts of the outer surface of a force 2 and a reservoir tank 4 of powdery molding material 10 is provided so that it can be lifted by a lift. Jet pipes 8 of compressed air are provided at the opening part of the tank 4 and louvers 9 are fixed on the lower side. The force 2 is filled with the powder material 10, and excessive powder material 10 is recovered in the tank 4, compressed air is jetted to remove antigelling powder from the force surface. The tank 4 is dropped, the temperatures of the necessary parts of the force 2 are lifted and gelled film 13 is melted and hardened to take the molding from the mold. |
