Abstract: A battery terminal includes an undercut groove that provides a leak proof seal between a battery terminal and a plastic battery cover or housing. The leak proof seal prevents electrolyte from seeping from the interior of the housing as well as prevents electrolyte from seeping between the battery terminal and plastic housing when the battery housing is filled with electrolyte.

Abstract: A method and apparatus utilizing a radial rolling process to cold form rings on a lead battery terminal with undercuts or overhangs to improve the sealing properties of the rings. The apparatus includes a fixture configured to securely position the battery terminal beneath a rolling station. The rolling station includes a radial rolling spindle having a plurality of cam shaped rollers configured to transform at least one ring on the battery terminal from having an initial rectangular cross-sectional shape into a desired arrowhead cross-sectional shape when the terminal and cold metal forming member are rotated relative to each other. A drive assembly is configured to rotate the battery terminal and radial rolling head relative to each other.

Abstract: A method an apparatus is disclosed for forming a battery terminal having a threaded hard metal insert received within an outer portion formed of softer metal such as lead. A preformed outer portion is deformed by an orbital head forming apparatus to secure the hard metal insert within the outer portion.

Abstract: A method and apparatus utilizing a ring forming head to cold form a ring on a lead battery terminal. The apparatus includes a seating station configured to securely position the lead battery terminal within a fixture. The apparatus further including a rolling head having a plurality of rollers, and a drive system for engaging and rotating the rolling head and lead battery terminal relative to each other. The terminal includes an anti-torque structure formed in the terminal to engage a battery housing at the exterior surface of the housing.

Abstract: A method and apparatus for forming stackable plastic battery containers having stacking grooves is disclosed. A hot tip injection nozzle is centrally located within a raised section of a die thereby forming a depression within the stacking grooves. The nozzle has a gate offset from the nozzle center line. In this manner, the gate remnant formed by the gate offset does not interfere with the stacking of the containers.

Abstract: A method and apparatus utilizing a single progressive die to cold form a finished lead battery terminal from a lead slug. The apparatus includes a lead pickup station, a progressive die having three stations, a drop off station and a transfer mechanism. The transfer mechanism indexes the lead slug from each station to the next with each cycle of the progressive die.
