A normalização das melhores práticas possíveis de modo a reduzir as variações e erros existentes num sistema, processo ou produto é essencial para a criação de processos eficientes, com elevada produtividade e com o menor custo possível associado, de modo a tornar as organizações aptas a responder ao constante aumento de exigência do mercado atual. Para isso, a disponibilização de informação a todas as partes interessadas de um processo e a formação de operadores são essenciais, de modo a aumentar de qualidade dos produtos. O presente trabalho foi desenvolvido durante um período de estágio, em contexto industrial numa empresa do setor têxtil, ERT Têxtil Portugal no departamento de engenharia do processo, e surge da necessidade de melhorar e uniformizar o processo de laminação chama. O projeto em estudo tem como objetivo a análise do processo de laminação chama de forma a identificar se existe alguma relação entre valores de adesão a frio e a quente, determinar parâmetros base para a produção de novos produtos e identificar e solucionar os problemas existentes ao longo das diversas produções. Para isso, foram necessárias a recolha de um número elevado de amostras, e a realização dos testes de adesão e espessura a quente aos mesmos, anotar os resultados obtidos e os parâmetros usadas na produção, e posteriormente, compará-los com os obtidos em laboratório e em outras produções do mesmo artigo. Após a análise dos resultados, foram propostas ações de melhoria que permitiram estabelecer quais os parâmetros ideais para a laminação de diferentes artigos de modo a estes apresentarem os melhores valores possíveis de acordo com as especificações do cliente. Os parâmetros estabelecidos foram atualizados em software, de modo a estarem disponíveis a todos os operadores, permitindo a uniformização dos resultados em diferentes produções do mesmo artigo, pois os parâmetros utilizados pelos diferentes operadores passaram a ser semelhantes.
The standardizations of the best possible practices to reduce the variations and errors in a system, process or product is essential to create efficient processes, with high productivity and low cost, in order to make the organization able to answer the constant increase in demand of the current market. So, make the information available to all interested parts and the formation of the operators are essential to increase the product quality. The present work was developed during an internship period, in an industrial context in a company in the textile sector, ERT Têxtil Portugal in the process engineering department, and it arises from the need of improve and standardize the process of flamebond lamination. The project under study aims to analyze the process of flamebond lamination to identify if there is any relationship between cold and hot adhesion values, to determine base parameters to produce new products and to identify and solve the existing problems along several productions. For this, it was necessary to collect many samples, and test them in terms of adhesion and thickness, note the results and the parameters used during the production, and subsequently, compare it with the obtained results in laboratory and in other productions of the same product. After analyzing the results, improvement actions were proposed that allowed the establishment of the ideal parameters for the lamination of different products, to present the best possible values according to the costumer’s specifications. The established parameters have been updated in software, to make it available to all operators, allowing the standardization of results in different productions of the same product, since the parameters used by the different operators have become the same.
