Injection moulding is a plastic-forming process used in the production of most of the plastic parts (about 70%) in automobile industries.The manufacturing industry has gone through significant changes in the recent years. For a good manufacturing plant, the most recommended thing is quality, efficiency and operating cost. These parameters depend on the function of the equipments used in the industry. Nowadays a remarkable improvement has taken place in the maintenance management of the physical assets and productive systems to reduce the wastage of energy and resources. Because of this, the organization should introduce a maintenance system to improve and increase both the quality and productivity continuously.OEE is one of the performance evaluation methods that are most common and popular in the production industries. In this work, the OEE of the injection moulding process was increased from 61% to 81% through the implementation of availability, better utilization of resources, high quality products and also raised employee morale and confidence.
