PURPOSE:To equalize the surface texture and dimensional accuracy of each panel, and to make the quality of a housing uniform in the housing composed of a plurality of the panels obtained by blow-molding a thermoplastic resin. CONSTITUTION:A unit panel monolithic-molded through one-time blow molding is cut and each panel 7, 8, 9 is acquired, and the hollow sections of each panel 7, 8, 9 are filled with fillers 17 improving the heat-insulating properties, sound insulation and rigidity, thus sealing the hollow sections. |
