摘要

The present invention relates to a method of manufacturing an air duct for an air conditioning apparatus for an automobile and an air duct manufactured therefrom, which is a conveying passage for air. According to the present invention, when two crosslinked polyethylene foams are foamed in a closed system, It is possible to easily manufacture an air duct molding formed with a hollow portion (v) to be an air transfer passage in an automated process. The manufactured air duct is lightweight, excellent in heat insulation, and has a shape suitable as an air duct.
