Written permission required from the department head for NON-IE and NON-UP students or researchers Submitted in partial fulfillment of the course requirements in IE 135 : Industrial Quality Control The group performed a quality control study on Jocelyn Forge Inc., which manufactures products made of steel. The company's product that was chosen to be analyzed is the Oval Eye Bolt, made from steel that is later galvanized, which is used for guying in electrical poles. The study focused on the production process of the bolt, looking for problems in the process and developing recommendations that the company may use in the future. Using FMEA and Ishikawa Diagrams, two main problem areas were identified in the production of the oval eye bolt. These are the process of Hot Dip Galvanization (HDG) and the process of Forming Up - Setting of Head of the bolt. In these two processes, the errors in production most likely occur, and are also the processes that are vital to making a defect-free oval eye bolt. Using control charts, it was determined that the two processes are in control. This means that the variability in the process is natural and may be beyond the company's control. The process capability of HDG is 4.5954 which mean that the process uses up only 21.76 percent of its tolerance band, thus there is a low fraction of product nonconforming. From the setting of head process it was determined that .33 percent of an average days of 600 bolts are produced nonconforming. The group recommends the automation of the processes and to maintain proper training of the workers. A cheaper alternative is to buy a voltage regulator, which for a time frame of five years will bring up a profit of PhP 2641.93. The group also recommends that the sampling plan of JFI be changed to ANSI standards, which requires less sample sizes per lot sizes and therefore cheaper at larger lot sizes. The group firmly believes that the number of defects and inspection testing will be vastly improved by following our recommendations. Jocelyn Forge Incorporated. Steel industry and trade.
