    The preventive maintenance plan is fundamental for a company, because it is used to predict minor problems in machines and components before they present failures. That is why to carry out this technical project, the needs of the company "Halley Corporación CL" were taken into account, to have a preventive maintenance plan for the molds knowing how important it is to have one, this will help us to early detection of failures or damage that may occur in the molds and their components, in order to prolong their useful life and thus reduce costs. For the development of the maintenance plan, an inventory was started, where the current state of the molds is detailed, a list of components was also generated and technical sheets were made to then proceed with an analysis of failures and failure modes of the components by means of the AMFE matrix based on NTP 679, finally the Weibull mathematical and graphic model was applied according to NTP 331 to determine the reliability of the molds. Consequently, the numerical values and parameters necessary to configure detailed time intervals per month were obtained, with the help of logs and maintenance ranges where the corresponding preventive actions are carried out, to prioritize maintenance work.

    Desarrollo de un plan de mantenimiento preventivo en el área de fibra de la empresa Carrocerías Varma S.A. de la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-09) Vargas Tubón, Steven José; Castro Miniguano, Christian Byron
    The importance of maintenance in the machines of a company helps us to predict damage to components, reduce costs and extend the life of its components. For this reason, the objective of the following project is to do a preventive maintenance in the machines of the fiberglass area of Carrocerías Varma, starting from an inventory of the machinery where statistical data were collected, operation times, external valuation, creating technical data sheets where the information of each machine is detailed, external valuation creating technical data sheets detailing the information of each machine proceeding first to apply the calculation of availability, failure analysis with the AMFE matrix in accordance with NTP 679, Criticality Analysis and finally proceeded to apply the mathematical model and graphical Weibull under the NTP 331 in order to determine the availability of each of the machines. As a result, numerical values and parameters of each machine were obtained, necessary to structure maintenance schedules carrying out preventive activities with their respective frequencies of time in the daily work, ensuring to improve the functionality of the machines and equipment, thus extending the useful life and giving a greater rentability to the company.

    Desarrollo de un plan de mantenimiento preventivo y predictivo para el área de enderezada y pintura en la empresa Kia Motors S.A.
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-09) Lozada López, Carlos Rubén; Castro Miniguano, Christian Byron
    The constant search for methods to extend the useful life and reduce the unexpected stoppages of the components of the machines, has allowed the creation of maintenance plans that are of great help to the industries. For this reason, to carry out this project, we started from the technical specifications and the analysis of the current situation of each of the machines, then the components of each one were determined, later the analyzes were carried out to determine which are the ones that reach the fail more frequently, in this case the AMFE matrix was used, then the mathematical methods and Weibull graphs were developed for each machine, in these methods the data obtained from the failure statistic and also from the statistical equations intervened, This was done in order to determine the reliability that each of them will have. In this way, it was possible to carry out the maintenance ranges in which the dates on which both preventive and predictive maintenance must be carried out, all this research was carried out based on the NTP 331 and the NTP 679 prevention technical notes.
