In particular the paper leads to minimize the assembly time and reduction of product cost that is maximized because of wastage due to crack. The objective of this research was to maximize assembly productivity for AK103 at Gafat Armament Industry. The assembly system was analyzed using layout to represent assembly line and table to represent sub-assemblies. The time needed for each process is also studied. By maintaining the idle machineries and introducing continuity of assembly, the current annual capacity of assembly factory can be improved to 3400 products. Design and development of two jigs performed using available technology in industry. The jigs were tested and both jigs work well with some recommended corrections. One method of improving productivity was specifying cause of crack of the components. Study was made on 234 samples at different time for different purpose. For force fitted components, tolerance was also checked taking 3 samples for each fitting components. The other methods used to reduce assembly time were design of new assembly process layout and stating of recommended solutions for inefficient equipments. By appropriate designed layout and recommended corrections of machineries, production capacity may increase from 3400 to 20580 is conceived.
