Abstract: A method of manufacturing a hollow product using a draft angle is disclosed. A method of manufacturing a hollow product using a draft angle refers to a method of manufacturing a hollow product using a core having a draft angle. The core is formed to protrude in one direction and has an outer surface at a perimeter of a protruding portion of the core, the outer surface of the core forms a slope with respect to the one direction, and a cross-sectional area of the core decreases as the core goes toward a protruding direction. The method comprises disposing a mold to be spaced apart from the outer surface of the core, disposing a hollow tube between the core and the mold, injecting a molten metal into a space between the core and the mold, and removing the core when the molten metal is solidified and the hollow product is molded.
