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 dispen…
