A concentrated lubricant composition is described that can be diluted to form a diluted lubricant composition for use in hot metal forming processes. Concentrated lubricant compositions include triaryl phosphate esters; Non-ionic surfactants; Organic sulfur-containing extreme pressure additives; Amine salts of organic acids; And optionally sodium thiosulfate. Such lubricant compositions show improved performance in molding operations and produce parts with less part-to-part variation. |
