ルムｌを密着させて、真空成形する。First, as shown in FIG. 2, a sheet or film 1 made of a color soft and hard vinyl chloride resin, a blend of vinyl chloride resin and methacrylic resin, or two layers of vinyl chloride resin and methacrylic resin is shaped to approximate the surface shape of the decorative molding. In a vacuum forming machine 5 equipped with a mold 5a and a heater 5b, the sheet or film 1 is wound around the outer surface of the mold 5a and heated by the heater 5b to soften it.
The pressure is reduced from the bottom of the mold 5a, and the sheet or film 1 is brought into close contact with the mold 5a for vacuum forming.
