ABSTRACT:
A method and apparatus for casting straps onto the plate lugs of battery cell elements. The apparatus includes a rotatably indexable table having a plurality of mold and element carrying stations which each are successively indexed through a plurality of operating stations, including an element loading station, an element lug alignment station, a molten-metal pouring station, a lug fluxing station, a casting station, a plurality of mold cooling stations, and an element unloading station. The mold of each table station is adapted for efficient and precisely controlled electrical resistance heating and forced-air cooling during each cycle of operation. In the illustrated embodiment, each table-station mold is successively heated from electrical sources at a plurality of operating stations upon indexing of the respective table station to such operating stations and is cooled by directing air through air-direction tubes mounted on each table station in close proximity to the respective mold. The apparatus includes a master controller that controls operation of the plurality of table and operating stations and maintains optimum casting conditions in each mold and the molten metal dispensed therein at the time of casting.
