Abstract:
Waste batteries are raw materials for the process of obtaining secondary lead and when refined and applied in a process called hydrometallurgical, ingots are obtaneid , which is applied to an energy accumulator. The ingots might present some defects during their formation, which will impact the customer's process. In this way, and with an emphasis on customer satisfaction, strategic processes focused on quality were centralized and standardized in an area with the aim of optimizing costs, increase quality and production based on the QMS (ISO 9001:2015). Therefore, the entire performance analysis of the applied strategies was observed through internal and external performance indicators. The internal actions focused at improving the process were built based on the communication and collaboration interface between the areas of quality control, maintenance and production. The comparison of the first five months of the years 2023 and 2024, it is possible observe a minimization of the defects presented by the current product, in relation to the internal indicator. In relation to the external indicator, a positive variation of 15.44% is observed in relation to the customer satisfaction score, when analyzed in recent years.
