Esta tesis de Grado para la obtención del Título de Ingeniero Industrial, tienen por objetivo aplicar le herramienta de la manufactura esbelta, SMED, que simplifica cualquier cambio de matriz en la preparación de la maquina o procesos dentro del área industrial en un tiempo menor de 10 minutos, es decir en minutos de un solo digito. Para ello se siguió un análisis de procedimientos actuales, toma de tiempos, análisis de personal, estudio del lugar de trabajo, implementación de mejoras o herramientas automatizadas, capacitación al personal y sobre todo guiándome en el proceso de Single Minute Exchange Of Die (Smed) que es parte del sistema de producción de Toyota. Finalmente luego de la aplicación del Smed, se analizó el proceso final, tomando los tiempos nuevos de cambio y su estudio para su mejora continua a lo largo del tiempo.In the actuality every manufacturing factory in the world are in constantly change, companies need to beincreasingly flexibleand mustadapt moreeasily and quicklyto these changes, companies are not able toachievethis, they areendangeredbecause with the passageofthe yearshas become a priorityto develop new technologies, new management techniques, new ways and work strategiesthat yieldsustainable competitive advantagethat allows them tostand aboveyour competitors. CONTINETAL TIRE S.A. isa company oflong historyin the industrial sectorofthe city of Cuenca, which has had toevaluate variousstrategies for stayingcurrentwithin thenational and international marketdue tothe current situationthat existsglobally intheeconomically,like manyother enterprisesof various kinds, which haveseen the needto changetheir market,because of thisis that the companyisobligedto seeknew waysofworkingthat will improveproduction processes, reduce costs, in order to get the bestprofit margin inthe scenario thatis being lived. The enterprise seeks to applythetoolsof Lean ManufacturingorLean ManufacturingcalledSMED(SingleMinutesExchangedofdies), particularly in the extractionofcommonground. The goal is toreducetool changetime, (Channel) oftheextruderat a timeto increase production, reduce operating times, performthework moreeasily andorderly, that is, to achievethe benefitsobtained by applyingthe toolsof the new philosophyimplemented bythe Japanese. Time studywasconducted, currentanalysistools, operators andstudymovementsof the job. Improvementsareproposedbased onSMEDtool, andstaffwas trainedon the newprocess of change inextruder machine, lifting time informationexchange, which evidenceda decrease in timeby about 50%, so achievedthe stated objective.Ingeniero IndustrialCuenca
