Diseño de un Plan de Mantenimiento Preventivo para Hornos y Chillers de la Planta de Producción de la empresa Baena Mora & CIA

Abstract

Baena Mora & Cia is a Colombian company dedicated to the manufacturing of men's footwear and leather goods. For this purpose it has a wide range of machinery, one of which is the thermal conditioning line, machines which are distributed across all lines of production becoming indispensable equipment for the manufacturing process of the articles. Currently, the company is implementing corrective maintenance, causing unexpected shutdowns of the machinery. This partial stoppage of the production line where the equipment is located means that the company does not comply with the established production costs, and must incur additional costs due to working overtime to comply with production commitments, generating economic losses and non-compliance with their customers. Therefore, the present work has the purpose of proposing the implementation of a preventive maintenance plan in order to reduce and control the faults presented in the equipment and to reduce those lost due to inactivity.

In this project, the analysis of the functioning and current state of the machinery in the studio is carried out, which are 13 pieces of equipment between ovens, chillers, and vaporizers. Developing a Pareto analysis, the critical machinery of this group of machines were recognized, for which they applied the AMEF analysis and the methodology of cause and effect the 5 Whys. This being the basis for the approach of preventive maintenance routines which will be carried out according to the design of the schedule of activities established for one year.

Finally, the cost and benefit analysis of the implementation of the designed maintenance plan was developed, it being relevant that the value of this implementation represents approximately 0.16% of the total cost of maintenance interventions in the previous period, the period which covers the month of October 2021 to the month of October 2022. This system will gradually reduce the possible faults existing in the equipment, increase the operating times of the machines and reduce operating costs.
