This assembly cell, of semi-automatic operator loaded machines, produces a range of single stage air bag inflators. The assembly cell is arranged in a "U" shape and single part flow is maintained through the process. A supervisory control and traceability system coordinates the cells, and collects important assembly and test data. The system starts by applying an in process bar code label to the upper housing and then resistence welding an orientation pin to the housing. The next operations press an ignitor retainer into the upper housing, and laser welds it in place. An ignitor is then loaded and crimped in into the retainer, and a shorting clip is installed. At this point an enhancer charge is dispensed by weight and loaded into the retainer, and is closed up by crimping a sealing disk in place.
