ABSTRACT:
A stock material for producing seamless containers from a black plate base includes applying a layer of insoluble crystalline phosphate to each surface of the black plate and subsequently producing a thin film of organic lubricating material on the exposed surfaces of the phosphate layers so that a drawn and ironed container can be produced from a flat blank without the use of any additional lubricants during fabrication. The weight of the phosphate layer for each surface of the black plate base is preferably less than 100 milligrams per square foot, while the weight of lubricating film is on the order of 70 to 360 milligrams per square foot. In the preferred embodiment, the phosphate layer is preferably in the range of 20 to 35 milligrams per square foot, and the lubricant layer is on the order of 70 to 180 milligrams per square foot.
