ABSTRACT:
An improved method to lubricate a metal workpiece at elevated working temperatures is described employing a novel liquid lubricant preparation which includes a vaporizable and polymerizable alkyl aromatic phosphate ester in combination with a die release agent selected from the group consisting of an organic binder and a fatty acid soap, to include mixtures thereof. The applied preparation forms a solid polymer lubricant in the forming die at the elevated working temperatures enabling lower applied pressures to be employed while producing superior workpieces.
