The company in this research supplies the automotive lamps to many automotive manufacturing companies. The research focuses on the Rear Lens Combination Lamp Injection Process which causes a lot of silver line defectives and has the most impact on customer viewpoint. The DMAIC phases of the Six Sigma methodology are applied to solve the problem. New parameters are set at the optimal values as the result of the experimental design and analysis. After the improvement is implemented, the silver line defects are reduced from 10.21% to 2.41% (7.8% defect reduction)
