Abstract
A lead billet having a large outer diameter cylindrical section and a small outer diameter cylindrical section is positioned in a cavity formed of fixed and movable mold sections. Forcing a punch into the lead billet forms a hollow molding with one end closed. Both ends of the molding are then cut away. The use of a billet with two different outer diameters facilities the plastic flow of the billet material to form a collar with projections for preventing rotation of the terminal mounted with its foot in a cover of a storage battery. Uninterrupted ring ridges below the collar assure a positive seal.
