ABSTRACT:
A lubricant is provided to help in drawing containers such as cans from tinplate or coated tin free steel and to assist the metal forming process during drawing. The lubricant is formulated to permit a post spray without removal of the lubricant thereby eliminating washing and drying the container before post spraying. Post spray coatings are solvent or water based and are necessary to protect the container from the harmful effects of the material carried within the container and in turn to prevent contamination of the product by its container. A method of lubricating a metal to be deeply drawn into a sanitary can is explained and includes leaving the lubricant on the can during interior post coating operations.
