Control de calidad en la línea de producción de cuero de la empresa Curtiduría Promepell S.A.

Abstract

The present study is based on the analysis of the quality of the leather production line of the company Promepell S.A., located in the province of Tungurahua. For this purpose, a quantitative and descriptive methodology was used, which included data collection through check sheets, statistical analysis of the process, evaluation of the capacity through Cp indexes, as well as R&R studies to determine the reliability of the measurement system. During the diagnosis, the main defects affecting the quality of the finished leather were identified as: thickness irregularities, incorrect shades and grain looseness. These defects not only occur with high frequency, but are also repeated on a constant monthly basis, according to internal records and validation by the management team. Process capability indices revealed that several critical steps, such as trimming and finishing, have Cp levels of less than 1, reflecting excessive variability that compromises product conformity. As a result, an improvement programme is proposed based on actions such as parameter standardisation, incorporation of digital measurement technology, partial process automation and continuous staff training. In conclusion, the research shows that poor quality control has a direct impact on the company's competitiveness. The implementation of systematic improvements will not only reduce defects and increase efficiency, but also strengthen the positioning of Promepell S.A. in the regional leather industry, characterised by its demanding quality standards.
