Abstract Damper and Vibration Isolators are the most imperativeparts of an automobile to decrease vibration or noise. Today's competitive environment every manufacturing organisation has focused on high quality product with defect free operation to increase productivity and reduce manufacturing cost. In this work a manufacturing unit located in northern region in India have been taken which dedicated to manufactured Noise, Vibration and Harshness (NVH) parts. To manufacture NVH parts various processeswere studied through process flow diagram of manufacturing plant and it include degreasing, grit blasting and rubber to metal bonding through injection moulding. In order to manufacturethese parts, a major process which is required is injection moulding of rubber. In this process of injection moulding, various defects were analysed and identified with the help of Pareto analysis. These defects directly influence on efficiency, profitability and quality level of organization. With the application of Pareto diagram defects were prioritized by arranging them in order of their occurrences. Cause and effect diagram is being applied to investigateconceivable reasons of defects through brain storming session and identify the root causes of defects. This paper also suggests the possible solutions of major defects to improve quality level and productivity of plant.
