Este projeto teve início em novembro de 2019 terminou em novembro de 2020. Todo o trabalho foi realizado nas instalações fabris da Hempel (Portugal) S.A, que se situam em Vale de Cantadores, Palmela. Devido à situação pandémica que atravessamos foi necessário efetuar uma interrupção no estágio, que durou cerca de 3 meses. Os objetivos deste trabalho foram a implementação de controlo metrológico nas linhas de enchimento da Hempel Portugal, com vista ao aumento de rendimento da produção e do enchimento de tintas, o acompanhamento do processo de controlo de qualidade das tintas Hempel e o levantamento das condições necessárias para ser concedida uma certificação de produto. Na primeira parte do trabalho, foram instaladas balanças de controlo de massa com o objetivo de rastrear a massa dos produtos embalados, e dada formação aos operadores das linhas de enchimento, para possibilitar o manuseamento das balanças implementadas. Na segunda parte do trabalho foi estabelecida uma estratégia para aumentar o rendimento da produção de tintas recorrendo ao controlo rigoroso das massas das matérias primas e à escolha correta dos dissolvers e tanques de acabamento consoante os produtos a fabricar. Na terceira parte do trabalho foram feitas várias análises a tintas, previamente produzidas, com o intuito de acompanhar todo o processo de controle de qualidade das mesmas. Finalmente, foi feita uma pesquisa referente à possível certificação de produtos com o intuito de incorporar uma marca de conformidade numa gama de produtos da Hempel cuja massa não excedesse os 10 kg.
This project started in November 2019 and ended in November 2020. All the work was carried out at the manufacturing facilities of Hempel (Portugal) S.A, which are located in Vale de Cantadores, Palmela. Due to the pandemic situation, we are currently going through, it was necessary to make an interruption on the internship that lasted for about 3 months. The objectives of this work were the implementation of metrological control in Hempel's filling lines, in order to increase the yield of paint production and filling, the monitoring of the quality control process of some Hempel paints and the identification of the conditions needed for granting a product certification. In the first part of the work, new weight control scales were implemented to monitor the mass of packaged products. For the first part to be carried out successfully, it was necessary to train the operators of the filling lines. In the second part, a strategy was followed to increase the yield of ink production using a strict control of the masses of raw materials, and to correctly choose the reactors according to the products to be manufactured. In the third part, several analyses were made to the various produced paints, in order to monitor the entire quality control process. Finally, a study was carried out on the possible certification of products in order to incorporate a compliance mark into a range of Hempel products whose weight does not exceed 10 kg.
