Resumen
El objeto de este trabajo fue plantear una solución al problema existente en el área de perfilería estándar, basado en el enfoque de las técnicas de ingeniería industrial, se llego a encontrar el problema que causa mayores pérdidas económicas, siendo este el paro de máquina por montaje de rollo, teniendo como resultado un equipo con capacidad inferior a la demanda requerida. Como efecto tenemos una para momentánea de la máquina perfiladora cada vez que se termina un rollo de fleje hasta colocar uno nuevo en el desenrollador de la máquina, para posteriormente soldar la punta del mismo con la cola del anterior y pulir la unión soldada.
De acuerdo al resultado de la investigación se obtuvo que la línea tiene una eficiencia del 28.49%, llegando a la conclusión que la empresa tiene un costo de producción muy alto a causa de los tiempos improductivos que se ocasionan actualmente, causando una pérdida de $6,333.78 mensuales, generando una pérdida de $76,005.36 anualmente.
Como solución se propone la implantación de un acumulador de fleje con el fin de aumentar la producción de perfiles disminuyendo la paralización de la máquina, a un costo de $10,257.47. El tiempo de recuperación de la inversión es de dos meses, con un VAN de $59,764.54 y un TIR de 60.56%, mayor al interés de la banca privada.
The purpose of this study was to propose a solution to the existing problem in the area of standard profiles, based on the approach of industrial engineering techniques are ever find the problem causing major economic losses, this being the standstill Mount roll, resulting in a team with less than the required demand capacity. As to have a momentary effect of the profiling machine each time a roll of strip ends up with a new one in the unwinding of the machine, to subsequently weld the tip of the tail with anterior and polishing the welded joint. According to the result of the investigation it was found that the line has an efficiency of 28.49%, concluding that the company has a very high cost of production due to downtime that is currently causing, causing a loss of $ 6333.78 per month , generating a loss of $ 76,005.36 annually. As a solution implementing a strip accumulator in order to increase the production of profiles reducing the stoppage of the machine, at a cost of $ 10,257.47 is proposed. The time for payback is two months, with an NPV of $ 59,764.54 and an IRR of 60.56%, higher than the interest of the private banks.
