At this time, after extruding the shape part and a peelable dummy part together, a heat insulating material is filled into the gap formed by the shape part and the dummy part and bending is performed, and then the dummy part is extruded. Because this method involves peeling, it is different from the conventional manufacturing method for composite curved sections, in which a mold for forming an insulation material is once joined to the bent section, and the mold is removed again after the insulation section is formed. In comparison, there is no need to worry about insulation material leaking or high costs, making it extremely easy to manufacture shapes, and improving work efficiency, resulting in a significant increase in productivity.
