A concorrência e a competitividade no setor cerâmico, impõe que a qualidade de peças sanitárias produzidas seja um fator determinante no sucesso da empresa. O trabalho realizado, na empresa ARCH S.A., teve como objetivo um levantamento exaustivo dos principais defeitos apresentados pelas peças sanitárias inerentes ao processo de produção, e consequentemente a avaliação dos custos da não qualidade das peças em catálogo. Essa avaliação decorreu entre Outubro de 2017 até Março de 2018. Foram avaliadas várias peças destacando-se neste trabalho duas delas: bacia One Suspensa e a base de chuveiro luca 80x140 cm, correspondendo a primeira a uma das peças com maior número de vendas e a segunda à peça cujo encomendas foram mais baixas. Os principais defeitos encontrados foram: poro, racha, impureza e grão de refratário. Com a ajuda de diagramas de Ishikawa apontaram-se as possíveis causas do aparecimento dos referidos defeitos. A principal conclusão é que uma grande parte deles se deve à etapa de secagem. A necessidade de uma secagem eficaz e controlada é crucial para o sucesso da produção de peças conformes. Numa segunda fase, foram analisados os custos da não qualidade tendo em conta as peças que foram enviadas para armazém, as que sofreram retoques ou foram enviadas para quebras. Os principais resultados para a bacia One Suspensa situaram-se em custos totais de não qualidade em 23 433 € e para a base de chuveiro Luca 80x140cm em 2 351€, representando este custo em percentagem de 17.8% e 16.8% relativamente ao valor das vendas das referidas peças. Por fim foram também determinados os custos totais da não qualidade para todas as peças, sendo a média obtida de 52 713€ nos meses em que decorreu o trabalho.
Competitiveness and the ceramic sectorial competitiveness require that the quality of the sanitary ware is a key factor in the success of the company. The work carried out at the ARCH S.A. company had the objective of collection the data from the principal defects in the sanitary industries inherent to the production process, and consequently an evaluation of the costs of the non-quality of the pieces in catalog. This evaluation ran from October 2017 to March 2018. Several pieces were evaluated, highlighting in this work two of them: “One Suspensa” basin and shower base “Luca” 80x140 cm, the first corresponding to a piece with one of the highest number of sales and the second whose part orders were lower. The main defects were: pore, crack, impurity and refractory grain. With help from Ishikawa diagrams they pointed out the possible causes of the appearance of defects. The main conclusion is that a large part should be made in a drying step. The chance for effective and controlled drying is crucial to the success of building your stocks. In the second phase, were analyzed the costs of the poor quality considering the pieces that have been sent to the warehouse, suffered a retouch or were sent to losses. The main results obtained for the “One Suspensa” basin was in total costs of non-quality at 23 433€ and for the shower base “Luca” at 2 351€, representing this cost as a percentage of 17,8% and 16,8% of the value of sales. Finally, the total costs of non-quality for all parts were also determined, with the average obtained of 52 713 € in the months in which the work was carried out.
