METHOD FOR MANUFACTURING ROLL DIE FOR FORMING BARRIER RIB OF PLASMA DISPLAY PANEL, AND ROLL DIE FOR FORMING BARRIER RIB OF PLASMA DISPLAY PANEL THEREBY

摘要

A kind of method is used to form barrier ribs on a plasma display panel, and be easily provided to the form concave curved portion on an outer peripheral edge of roll die by a roll die of identical manufacture for manufacturing a roll die. One thin web (200) is wound on around the entire outer surface of a thread rolling die body (100), thin web, has the convex portion molding hole (210) of the micro-dimension formed among horizontal and vertical matrix. It is dipped in an electroplating container with the thread rolling die body wound of thin web, then thread rolling die body is susceptible to be electroplated. After plating, thin web is disengaged from thread rolling die body. Concave curved portion molding hole is used to form an exhaust gas flow tube with via holes each other and is connected to.
