Application of six sigma methodology in forging manufacturing plants: An example study

Abstract

Products which can meet market requirements and customer demand were created in a high response speed by original product manufacturer called OPM has been critical to competitive success. Six sigma methodology gave impetus to original manufacture in low cost for the purpose of near-perfect product and advanced service. Therefore, six sigma methodology obtained a popularity to perfect-quality in the field of manufacture industries. In this paper, an attempt that taken an assessment and improvement of dents on the top surface of product in forging plants was being made to apply six sigma methodology which was a systematic procedure driven by statistic data. The problem of product defects were discovered and defined in definite through critical customer requirement analysis. It was based on products measurement from the genesis of sampling in the process that first-hand data collected by quality control staff showed the information in essence including critical causes of dents and what issues they created by means of statistics and management in science. Regarding these critical reasons and what the effect they brought about in actual, counterpart measurement and proposal were designed and taken out in nature, which run as an experimental plan of effect verification. It was preeminent testimony that six sigma procedure was applied to take an implementation in forging plants has contributed to high quality of product enormously and effectively.
