Abstract
Arms Corporation of the Philippines (Armcor), located at ARMSCOR Ave. Brgy. Fortune, Marikina City. is the biggest firearms and ammunitions manufacturer in South East Asia. Armscor has been producing firearms and ammunitions since 1980. Rejects became a big problem in the centerfire cartridge production line of ammunition division specifically in the centerfire production line, thus, a need for an inspection process. The said production line is experiencing 7% rejects out of the 13.5 million cases produced monthly. Of these rejects 45.11% is attributed to the head turning process, the process where the dimensions of the cases are made. The company incurred a cost of PhP28,251,360 annually due to the rejects and the inspection process labor cost. As a consequence, the firm wants to reduce rejects to the tolerate amount of 6% of the total yield, and to remove the gauging process if the yield reaches the 94% mark. The root causes of rejects were identified and analyzed using Ishikawa diagram. The root cause analysis showed the five kinds of rejects that comprise the vital few, and with CNX analysis, causal factors were identified to evaluate Controllable, Noise and Experimental factors affecting the problem. Attitude problem of operators and cost that will be in cured due to inspection are the noise factors On the other hand, lack of training of operators, no standard procedure on handling the machine/cases, lack of supervision, old machines and no blower to remove fillings and for cooling are the controllable factors. There is no Experimental factors seen when the Ishikawa diagram is established. The solution generated were re-training of operators, proper supervision, improving the tasks of the operators, reconditioning of machines and replace the machines, plausible solutions, like proper solutions on operators and improving the tasks of operators, were tested. If continuously implemented, it will result to an annual savings of PhP27,153,735.00 and the production yield of the head turning process will have an increase of 4%, from 93% to 97%.
