ABSTRACT:
A forming jig comprises a rectification plate having two or more material supply holes, a drawing die installed below the rectification plate to specify the external configuration of the formed body produced from a material, and a floating die in which two or more wires float vertically in spaces in the drawing die, forming pattern passages, and stretch from an exit section of the drawing die to form a hollow hole-forming pattern. The forming jig can easily and inexpensively design or change the design of a forming pattern of hollow holes and the external configuration of a formed body, and can form fine hollow holes at a high density.
