Abstract

This project is to investigate the root cause of defects of the glass run channel that occurred during the transfer the moulding process. The glass run channel is to prevent rain or water entering the vehicle and act as motion guidance for glass window either to be raised or lowered. The purpose of this investigation is to find out what are the element that cause the defects. Defects of the glass run channel are varies such as bubbles, short moulding, sink mark, flow mark, excessive flow, void and dirty. Thus, this project will be focus on short moulding (incomplete moulding) and bubbles only. The methodology used are in order to tackle the issue by using quality control tools approach that is based on four influencing factor or called as 4M analysis (man, method, machine and, materials). Studies on literature from open sources such as internet have been performed in order to identify the possible element of the defects. A visit and discussion had been carried at the production line and the questionnaire has been distributed to the relevant operator and data were collected. Based on the result gathered of this root cause analysis, the suggestion on how to solve the defects problem were proposed to the company in order to help them to reduce the rejection rate.
