MANUFACTURING METHOD OF GRID BASE BOARD FOR BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an economical manufacturing method of a thin and light-weighted grid base board for a battery with high quality by optimally combining a temperature of lead-alloy melting and and that of a casting mold at a book mold casting method. SOLUTION: In the manufacturing method of the grid base board for a battery of manufacturing the grid base board for the battery with a thickness of 0.5 to 1.2 mm by the book mold casting method, the mold is heated so as to have a temperature of 0.7 to 0.9 times as high as the melting point of the lead-alloy, and a molten lead-alloy heated so as to have a temperature of 1.7 to 2 times as high as the melting point of the lead-alloy is poured into the above mold. Afterwards, the book mold is cooled by an air spray when releasing it. COPYRIGHT: (C)2004,JPO
