Mejoramiento de los procesos de producción de cuero mediante la metodología SIX SIGMA en la Empresa Curtiembre Quisapincha

Abstract

The objective of this research was to improve leather production processes through Six Sigma methodology in Quisapincha tannery to ensure the quality of the products. The quantitative and qualitative research approach is presented as a method based on the application of DMAIC method (Define, Measure, Analyze, Improve and Control) during the diagnosis. Data about documents was collected from company and then identified what affects the production process, covering the production of leather, quality faults and customer requirements. Measurements were also taken of a sample of a leather band to verify the causes of the problems identified, based on the application of Six Sigma system. An evaluation of the measurement and capacity system was carried out; where a fault was found on a section of the operators where the percentage of repeatability and reproducibility analysis is high, with a 57.11% being the measurement system rejected, with a sigma level of 2.73; a CPK (Capacity Index) of 0.97. It was achieved with the application of improvements and a simulation to obtain a capable process with a CPK of 1.48; a Six Sigma level of 4.03 that satisfies; for every million opportunities it will have 272 100 defects or measurements that are out of specifications. Finally, fishbone diagrams are applied to identify problems and suggest careful diagnostics during raw material sorting to reduce production delays and improve productivity, faults and product quality for each task discovered.
