PROCESS TO MANUFACTURE LARGE FORMAT ALUMINUM BOTTLES AND ALUMINIUM BOTTLE MANUFACTURED THEREBY

摘要

A high speed manufacturing process for large format aluminum bottles (up to 750 ml) based on the DWI process that uses 3xxx can body stock with high recycled content. The process can include forming a bottle preform by redrawing, drawing and ironing, and doming a cup. The bottle preform formed by the process has a diameter of about 2.5" to about 3.0", a height of about 10.0" to about 12.5", a wall thickness of about 0.006" to about 0.020", and a dome depth of between about 0.400" to about 1.00".
