Tape casting is an important forming operation used to prepare flat sheets in the various industries. In this study, Doctor Blade tape casting of In-based low melting point alloy was carried out. The purpose of this investigation was to determine the possibility of applying the Doctor Blade tape casting process to the manufacture of low melting point alloy sheets that can be used as thermal fusible parts of battery safety systems. In-based molten alloy that has a melting point of 95oC was produced; it’s viscosity was measured at various temperatures. The molten alloy was used as a slip in the caster of the Doctor Blade tape casting system. The effects of the molten alloy temperatures and carrier speeds on the produced sheet shape were observed. For the casting conditions of 1.5 cm slip height, 120oC slip temperature, 0.05 mm blade gap and 60 m/min. carrier speed, an In-based alloy thin tape well shaped with 0.16 mm uniform thickness was continuously produced.
