Evaluation of new cold forging lubricants without zinc

In the case of cold forging, the lubricant may either be an extrusion oil or a soap. Because of a physical or chemical reaction that occurs between the lubri-cant and the pre-coat, the lubricant adhesion to the billet is improved. This is what allows the lubricants to withstand the high-pressure sliding conditions and large surface expansions
