Optimización del proceso productivo de bolsas plásticas en la empresa M&M Plasticotopaxi, ciudad Latacunga – Cotopaxii

Abstract

The company M&M Plasticotopaxi-Latacunga faces a problem of low quality plastic bags, which generates economic and customer losses due to complaints and returns of finished products. The objective of the research consisted of optimizing the production process of plastic bags through the application of statistical quality tools. First, an analysis of complaints and claims was made, which revealed that 74% of the complaints were related to defects in burnt bags and bags in general. Also, it was observed that 37% of the waste corresponded to tons of product rejected due to burnt bags, which generated a total loss of $18,512.04 during the period from 2020 to March 2022. After using tools such as Check List, brainstorming, 5 Why? and Ishikawa Diagram, problems were identified in the Extrusion, Cutting and Sealing operations due to poor maintenance, lack of control in the extrusion process, lack of personnel training and lack of adequate tools. A total investment of $4,854.37 was proposed to solve the problems detected. In addition, a financial analysis was performed, which showed a Net Present Value (NPV) of $6,159.14, an Internal Rate of Return (IRR) of 27% and a Payback Period (PR) that would be covered over the course of May to June. These results indicated the profitability of the project and its ability to generate added value. The initial investment complies with a requested rate of 8.09% and also presents a surplus of $6,159.14. In conclusion, it was possible to identify the critical points in the production process of plastic bags at M&M Plasticotopaxi-Latacunga. The proposed investment was profitable, improving the quality of finished products and satisfying customers by reducing complaints and returns.
