This research work was carried out in a plastic company engaged in the injection and blow molding of plastic products. During the analysis of the Production area, it is noted that the company has an unsatisfied demand of 206.84 Tn per month on average of processed plastic material. In order to determine the problem, the OEE of the production is evaluated and it is found to be at 50.9 %, which is below a world class company that has 68.5 % (Ames et al., 2019). When reviewing the components of the OEE (availability, performance and quality), it is found that the availability is the lowest with 65.5 %. Along these lines, it is determined that the problem is the low availability of plastic injection molding machines. In order to determine the causes, the working hours of the machines are evaluated, in which there is an excess of 189,498.16 hours downtime. This is due to three areas: Maintenance, Tool and Die Making and Injection Plant, which represent 75 % with 64,150.00 h, 45,184.00 h and 32,846.16 h, respectively. The main causes are: Electrical, hydraulic and electronic faults, defects in the molds of the cooling, heating and ejection systems, delays in the regulation and mold change. The economic impact of these causes is $4,518,583.63 per year, which represents 24.25 % of the annual margin. Our proposal is to implement the Lean Manufacturing methodology and its engineering tools such as: 5S as a pillar of all tools, TPM with preventive, autonomous and predictive maintenance for machines and molds, SMED to reduce mold changeover times and standardization of processes.
