Resumen
Analizar el proceso del producción de cumbreros Duratecho Plus y proponer su mejoramiento mediante la adaptación mecánica en la máquina paneladora Guayaquil de la empresa NOVACERO S.A. Para el efecto, se aplicó la metodología descriptiva, cuali – cuantitativa, deductiva, con uso de TOC, diagramas de Pareto e Ishikawa, cuyos resultados evidenciaron que la producción de cumbreros se encuentra restringida por causa del operador que efectúa las dobleces, quien trabaja al 71,23% de la capacidad que puede realizar el operador de cortado, reduciéndose la capacidad de 48.000 a 34.192 unidades, a lo que se añaden los problemas del reproceso, demoras, ausentismo y falta de stock, que han reducido la eficiencia al 52,97%, con una producción anual de 25.426 cumbreros, cuyos problemas prioritarios fueron el cuello de botella y el reproceso, siendo las causas esenciales la falta de mecanización de este proceso que se realiza manualmente, generando tiempo improductivo y pérdidas económicas por $31.522,54. Se planteó como alternativa la adaptación mecánica consistente en diseño de matricería, compra de accesorios, fabricación de rodillos para conformado de lámina y pruebas respectivas, para la minimización de la restricción hallada, que contribuirá a la reducción de los costos de mano de obra y de producción en la elaboración de cumbreros Duratechos, concluyéndose que se superará la restricción del sistema, se incrementará la capacidad de la planta a 48.000 unidades anuales, y la eficiencia a más del 90%, obteniendo una TIR de 57,93%, VAN de $82.814,12, recuperándose la inversión en dos años, por consiguiente la inversión es factible.
To analyze the production process of Duratecho Plus roof ridges and to propose their improvement through the mechanical adaptation in the Guayaquil paneling machine of the company NOVACERO S.A. For this purpose, the descriptive, qualitative - quantitative and deductive methodology was applied using TOC, Pareto and Ishikawa diagrams, which results showed that the production of heads is restricted because of the operator who performs the folds, who works at 71.23% of the capacity that can be performed by the cutting operator, reducing capacity from 48,000 to 34,192 units, to which are added the problems of reprocessing, delays, absenteeism and lack of stock, which have reduced efficiency to 52.97%, with an annual production of 25,426 ridges, which priority problems were the bottleneck and reprocessing, being the essential causes the lack of mechanization of this process manually done, generating unproductive time and economic losses for $31.522.54. An alternative was the mechanical adaptation consisting of die-casting design, purchase of accessories, manufacture of laminating rollers and respective tests, in order to minimize the restriction found, which will contribute to the reduction of labor costs and production in the elaboration of Duratechos, concluding that the system restriction will be overcome, the capacity of the plant will be increased to 48,000 units per year, and efficiency to more than 90%, obtaining a TIR of 57.93%, NPV of $82,814.12, recovering the investment in two years, therefore the investment is feasible.
