PURPOSE:To contrive to enable painting and fixing operation to be easily achieved without the deterioration of a product by a method in which while painting a desired indication part on the inner surface of a mold with the ink in which pigment is mixed with heat fusible material, the synthetic raw resin having a lower melting point than that of the ink, is introduced into the mold, and then the indication part is painted and fixed to the surface simultaneously with molding. CONSTITUTION:An indication part 2 is painted at the desired position on the inner surface of a mold 1 with ink in which pigment is mixed with heat fusible material. The ink is made by mixing desired pigment with heat fusible material, e.g. paraffin and microwax. Next, the polyethylene powder as molding raw material is received in a mold 1, and is molded under heating. Then, by the molding under heating, paraffin and microwax are molten with the progress of a molding 4, and are taken into the surface of the molding 4, and then are solidified and stuck thereto with the solidification under cooling of the molding. Consequently, the molding is finely finished, and its separation does not occur.
