    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.
