In recent years, plastic has been part of the value chain of many different products, becoming a final consumer good. The enormous value of the plastics industry is beneficial for those who are part of the chain, reflected in the enormous figure of 1 trillion dollars a year, that is, 5% of the total trade of goods worldwide. This research is oriented to examine 3 tools to achieve a new model to optimize and improve the level of service, due to late delivery times and poor quality identified as the main problems within the company studied. The proposed model uses tools such as: Improvement of mold change time through the SMED Engineering tool, improvement of the organization and production tools through the 5S Engineering tool and improvement of operational efficiency under a Total Productive Maintenance approach obtaining an improvement for the company. Achieving an integrated model to improve the level of service that is suitable to be replicated in manufacturing companies.
