    The current research work aims to carry out a study of times and movements in order to suggest proposals to improve the production processes of the most demanded product in the metal-mechanic area of “Ecuatran S.A.” company, placed in Ambato City, which is dedicated to the manufacture and repair of electrical transformers. This research work used a qualitative-quantitative methodological approach. The qualitative approach involved direct observation, which helped to get general information about the company and the production processes. The quantitative approach was used to identify the most demanded product through an ABC analysis. In addition, the study of times and movements helped to determine the standard times and the production capacity for each process and sub-process of manufacturing the 25 kVA substation single-phase transformer. Due to the calculation of the production capacity, the bottlenecks were identified for each main process such as, lids, closing bands, and tanks through the analysis of the workload of each station and the current line balancing efficiency of each process. Subsequently, unnecessary activities were identified and eliminated to balance the workload per station only with essential activities that add value to the production processes. Because of the proposed line balancing, it was possible to obtain an improvement in balance efficiency. Regarding the forming of lids, there was an improvement of 79.06% and in terms of the forming of tanks, there was a 14.75% increase in efficiency and in productivity of 40.6% y 20.94%, respectively. With the proposed balancing of the lines and the calculation of the time required for the painting of lids, closing bands, and tanks, the established production demand could be perfectly covered. Finally, the proposal for implementing the 5'S philosophy is proposed since several problems have been observed regarding order and cleanliness. Therefore, several improvement alternatives have been developed for each phase in order to optimize the work environment and the performance of the productive flow of the company.
