PROBLEM TO BE SOLVED: To manufacture a blow molding having an excellent decorative surface by preventing the residue of the air between a decorative sheet and the molding to manufacture the molding decorated at the surface with the sheet by disposing a preforming in a blowing mold and disposing the sheet between the preforming and the mold, and blow molding it. SOLUTION: As a decorative sheet 2, a sheet having air permeability is used. The surface of a mold in contact with the sheet 2 is formed of a porous plate 3, and the air is sucked between a preforming 7 and the sheet 2 via the plate 3 at the time of blow molding. Accordingly, to blow mold, the residue of the air between the sheet 2 and a blow molding 8 is prevented so as to suck the air between the preforming 7 and the sheet 2, thereby making it possible to form an excellent decorating surface. |
