<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a blow-molded article, wherein only the neighborhood of the surface of a joint edge surface is melt at instant, thereby, even an blow-molded article of a complicated shape is molded with a high size accuracy and the sufficient joint strength is ensured. <P>SOLUTION: By using a moving mold 3 and a fixed mold 1, first and second half-molded articles A, B are molded so as to have joint edge surfaces a, b. While leaving the second half-molded article B, the moving mold 3 is slid, respective joint edge surfaces a, b are aligned, a heater 41 comprising a halogen heater or a carbon heater is inserted between the joint edge surfaces, the heater is retreated after the joint edge surfaces are melted, then, the mold is clamped and the joint edge surfaces a, b are welded. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
