PURPOSE: A bending mold is provided to reduce the bending processes by removing the need of machining oil and thereby excluding a machining coil spray process and a degreasing process. CONSTITUTION: A bending mold comprises a punch(11) made of metal, a die(21), and a resin material(50) which has good slip property and is coupled to a machining protrusion of the die. The resin material is made of MC nylon, and fastened with a metal compression element to a coupling groove formed in the machining protrusion.
