PURPOSE: A method for manufacturing a combining unit of a string of shoes is provided to improve an efficiency of an operation and prolong a lifetime by integrally forming a ring iron, a hole iron, and a connection pin in one metallic pattern, thereby preventing the combining pin from being come off caused by an impact or a wear. CONSTITUTION: A core is inserted into a metallic pattern(100) having a ring iron forming hole(8) and a hole iron forming hole(9) connected to a mold inserting hole(4), a core hole(5), and a combining hole forming hole(6). In addition, a boiled mold is inserted through the mold inserting hole(4). After solidifying the boiled mold, the core is removed from the metallic pattern(100), and a formed shoes string combining unit is extracted. A surface of the formed shoes string combining unit is processed by a sand blasting, and a formed connection unit is removed.
