Abstract

The defective product that contribute to the product quality problem is the main issue of this study. While, this paper aims to deploy Lean Six Sigma framework to facilitate the reduction of defective products and improve the process variation for moulding process. This study is carried out on the moulding process of Konica Minolta Business Solutions (M) Sdn Bhd. There are a bundle number of defects are identified on the parts that may affect the productivity of firm. The integration of Lean and Six Sigma will apply to reduce quality defects and process variation with DMAIC methodology. An overview of this thesis are drafted by using problem definition, project charter, process flow chart and line graph of occurrence number of defective products. Furthermore, data were collected on all possible defective product. In this paper, the root causes responsible for the occurrence of defect types on mould products are analysed. For that, the historical records of the occurrence number of defect type from December of 2018 until May of 2019 were analysed, leading to the identification of flash and gate flash defects as the main factor responsible for product quality problem in moulding department. Other than that, investigation of a cause-and-effect diagram is carried out. This leads to the potential sources responsible for flash and gate flash are listed out according to the four main factors. While, an improvement plan is investigated to develop a solution for the main issues. The critical defects is identified and solution that responsible to the cause is discussed. The outcome of this study is to propose an improvement plan to reduce the quality defects and improve the variation of moulding process. A suggestion is proposed on future research which are the Lean Six Sigma framework could be implemented on other production line
