Título: MELHORIAS NO MOLDE DE INJEÇÃO PLÁSTICA PARA VEDAÇÕES DE PORTAS DE AUTOMÓVEIS Autor(es): Camargo, Luis Davy Silva de Primeiro Orientador: Oliveira, Fabiano Faria de Abstract: This work's main objective is to develop an improvement in a plastic injection mold for automotive seal parts. This improvement was necessary due to a fault blocked by the parts assembler. The failure addressed was a leak of plastic injection material in a visible area of the part, or that was improved in an unpleasant aspect of the vehicle and that deviated from the standards defined by the manufacturer. The fact occurred within the assembly line of the assembly plant, which caused the vehicle assembly line to stop for 4 minutes and consequently the assembly of the assembly plant required a parts manufacturer to bear the expenses of the line stoppage and in addition to carrying out an assembly of the pieces 34 pieces that seemed to be the fault. Therefore, it was necessary to act quickly and objectively to correct the failure evidenced by the assembly. For this to be possible, some quality tools will be used in the studies to assist in understanding the failure and its causes and to assist in the management of solutions proposed by the multifunctional team.

Título: MELHORIA CONTÍNUA: ANÁLISES E MELHORIAS DE PROCESSO DE PRODUÇÃO NA CÉLULA 258 VISANDO O AUMENTO DE OUTPUT DA PEÇA GUARNIÇÃO PARA VEDAÇÃO Autor(es): Martins, Lucas Carvalho Primeiro Orientador: Oliveira, Fabiano Faria de Abstract: This work aims to increase productivity and improve the use of labor in the polymer injection process, specifically in the production of sealing parts for the automotive sector. The research was conducted in an automotive company, where high productivity is essential to meet the demands of car manufacturers. The study focuses on the technical analysis of the parameters of the EPDM injection process in the injection molding machines, as well as mapping the layout flow and the execution of manual tasks by the operators. By identifying opportunities for improvement in the settings of process parameters and in the operations carried out by the workers, the work aims to increase production capacity, reduce cycle times and, consequently, improve the company's profits. The implementation of these technical and operational improvements aims to optimize the use of human resources and guarantee the best return on the investments made in the project. The study also highlights the importance of testing and analysis for productive growth and efficiency in the production process.

Título: MELHORIA NO CONTROLE DA EFICIÊNCIA DO SISTEMA DE REFRIGERAÇÃO EM MOLDES METÁLICOS: Desenvolvimento de um teste na refrigeração durante setup. Autor(es): Gonçalves, Luiz Felipe Antônio de Medeiros Primeiro Orientador: Guedes, Luiz Carlos Vieira Abstract: This work deals with the implementation and testing of a device designed to improve the control of the efficiency of the cooling system of molds used in casting, in an aluminum wheel manufacturing company, during setup. The main objectives were to reduce delays in setup related to problems in the cooling circuits and improve the effectiveness of these circuits in production, factors that negatively impacted productivity. In order to achieve the main objectives, pertinent bibliographic reviews, analyses of the processes related to the company's casting sector, development and testing of the device were carried out. The device was tested in June 2024, and through this test it was possible to collect data to prove the feasibility of the improvement. The data indicated a total elimination of delays in setup related to the cooling system, previously responsible for production loss. In addition, the introduction of the device allowed for more precise control of the mold temperature, resulting in improved thermal efficiency and greater uniformity in casting. There was also a significant reduction in part defects and an increase in the useful life of the molds, thanks to targeted preventive maintenance based on monitoring of the circuits. The positive results point to the viability of expanding the use of the device to other areas of the production process, promoting additional gains in efficiency and quality in the production of aluminum wheels.

Título: GESTÃO DA QUALIDADE: um estudo de caso em uma linha de produção de uma indústria de montagem eletromecânica Autor(es): Mendes, Gabriel Azarias Primeiro Orientador: Pereira, Matheus Henrique Abstract: This work addresses the implementation of a quality management system in the production line of an electromechanical assembly company. With the use of quality tools, we seek to reduce rework, waste of materials and assembly time, in addition to improving stock control. The standardization of layouts made it possible to reduce assembly time by 30% and material consumption by 14%. The organization of the stock of previously cut channels and rails, now controlled by Excel spreadsheets, and the future implementation of specific software will facilitate material control. Reducing rework and improving process consistency reduced product production time and consequently increased customer satisfaction and productivity. This study demonstrates that the application of quality methodologies promotes more efficient, sustainable and integral processes, favoring the company's growth and excellence.
