Abstract

Miyoshi Technologies Philippines, Incorporated is part of the Miyoshi Group of companies. It was established on November 11, 1999 and started its operations on April 2001. On march 2008, the company received a request from Panasonic Communications Philippines Corporation (PCP) to manufacture 3 new parts namely Cover Front Bracket, PLate Exit, and Plate Speed Up Assembly or collectively known in the company as China Art. These 3 parts are to be used for a multifunctional printer that is to be assembled at PCP. The actual mass production of these 3 parts started on July 2008. From the production yield gathered from July to December 2008, the rejection rate and production yield of the 3 parts exceeded the company;s allowable rejection rate (2%) and did not meet the target yield (98%). The average rejection rate for Cover Front Bracket from July to December 2008 was 4.19% and the average production yield was 95.81%. On the other hand, the average rejection rate for Plate Exit was 9.94% and the average production yield was 90.06%. The average rejection for Plate Speed Up Assembly was 3.60% and the average production yield was 96.40%.The objective of the study was to increase the production yield of the 3 parts to more than 98% and the reduction of defective parts to less than 2%. From the data gathered from July to December 2008,in which all 3 parts did not meet the company's target production yield, different kinds of defects were identified. Four types of defects were identified from the 3 parts during the six-months period. It was observed that 87.7% of the total number of defects encountered by the 3 parts was dimension out or dimensional problem defects encountered by the 3 parts was dimension out or dimensional problem defect. Root cause analyses were done to determine the main causes of the problem. Also CNX analysis was done. Four controllable factors and three experimental factors were considered. The recommendations for the controllable factors were, for Factor A, the machine operators must be required to wear their ear plugs and safety gears to prevent them from being distracted while working. Also, the newly hired operators must be oriented properly by old operators or by their supervisors to prevent them from committing unnecessary errors. For factor B, The in-process operators must be required to at least be familiar with the specifications of the products critical checkpoints. They should also be provided with a list of the specification of all specification of all the products' critical checkpoints. For Factor C, the newly hired tooling operators should oriented properly and the die sets should have labels attached on them. Further for Factor D, the company must have constant communication with its customers to avoid miscommunications regarding measurements orientation. On the other hand the recommendations for the experimental factors were, for Factor A- conduct series of trainings for operators headed by the company's supervisors, for Factor B-install metal guides on the die sets and for Factor C- buy a brand new 60-ton press machine.Upon implementation of the recommendations to the problems, it was found out that the production yield for Cover Front Bracket would increase from 95.81% to 99.41%, while the production yield for Plate Exit would increase from 90.06% to 98.60%, and the production yield of Plate Speed Up Assembly would increase from 96.40% to 99.49%. The company would thus save up to ₱79 763.67 for 5 years.
