Abstract
A method of forming a battery terminal of the type having an electrically conductive screw encased within a conductive material casting such as lead. The preferred method uses a pair of die halves axially aligned with one another. A casting of a battery terminal having upper and lower terminal portions is provided, along with an electrically conductive post or screw. The casting and screw are placed between the die halves. The die halves are compressively forced against one another. A forging cone causes the casting to be forced into the thread spaces of the screw or against the surface of the post and changes the exterior angle of the casting.
