Manufactura esbelta y su aplicación en el mejoramiento continuo del proceso productivo de templado de vidrio de la empresa SEGUVID

Abstract

The purpose of this research work is to analyze the lean manufacturing tools and their application in the continuous improvement of the glass tempering production process of the SEGUVID company. Talking about continuous improvement refers to the constant elimination or reduction of waste, which will not add value to the final product, so that the company is strategically positioned in an advantage over its competition, this through the efficient use of lean manufacturing tools. Due to the company's production lines, an ABC analysis of two (2) levels is carried out in order to select the line with the highest demand and the glass thickness with the highest requirement, resulting in clear structural glass of 10 millimeters with four perforations with a diameter of 19 millimeters. For the analysis of the tools, the collection of process information is required, therefore, a time study is developed that serves as the basis for the development of the value flow map, the identification of waste and, consequently, the approach of a proposal that allows continuous improvement. The identified wastes cover a total of four being these: (1) Waiting, (2) Transportation, (3) Inventory and (4) Reprocessing, for which an improvement proposal is established using lean manufacturing tools such as Process Optimization. Process to reduce the standard time by 40.00% in the cutting process, Visual Control to improve the flow of documents and production orders, Line Balancing to improve the theoretical daily production capacity from (189.16 to 284.02) m 2, Poka Yoke to avoid reprocessing in the drilling area, 5S to generate a harmonious work environment and Plant Distribution to reduce the cost of glass transportation, which goes from $0.60 to $0.48.
