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.

Method for deep drawing thin metal stock into containers and thereafter

A method and tool for drawing and ironing and bottom profiling a container in a single process operation is disclosed wherein the ironing does not take place during the bottom profiling operation and the precoating of the container side wall is not damaged during removal of the punch because of a specifically configured undercut portion of the punch wall.
