Rediseño de los elementos y sistemas mecánicos en el proceso de aplicación y secado de pintura automotriz en la empresa Ciudad del Auto CIAUTO Cía. Ltda

Abstract

This technical project was developed at the Ciudad del Auto CIAUTO Cia. Ltda. company, specifically in the paint shop, where opportunities for improvement were identified in the automotive paint application and drying process due to operational wear of mechanical systems, energy losses, accumulation of contaminants, and the need for technological modernization. The importance of this topic lies in the fact that the current automotive industry demands more efficient, safe, and controlled processes capable of maintaining the surface quality of vehicle bodies, reducing downtime, and optimizing energy consumption. To address this, the redesign of thermal furnace No. 2, the flash-off zone, and the technical evaluation of electrostatic spray guns were proposed. The methodology applied combined field research, a literature review, analytical calculations, structural analysis, heat transfer, CFD simulations in ANSYS Fluent, modal verification, WBGT evaluation, and functional validation under real operating conditions. The research focuses on mechanical design, energy efficiency, applied fluid mechanics, industrial safety, and the improvement of production processes. As a technical proposal, industrial structures were redesigned and built to improve thermal insulation, contaminant extraction, and the system's operational stability. The innovative aspect of the work lay in integrating simulation tools, experimental calculations, and industrial assembly criteria to modify existing systems without compromising production continuity. Ultimately, the results demonstrated technical feasibility, operational improvement, a reduction in thermal risks, and a direct contribution to the reliability of the automotive paint painting and drying process within the industrial production matrix.
