Abstract

"PROCESSO PARA A FABRICAçãO DE UMA UNIDADE DE VáLVULA DE ESTRANGULAMENTO NO PROCESSO DE FUNDIçãO POR INJEçãO DE DOIS COMPONENTES". A invenção refere-se a um processo para a fabricação de uma unidade de válvula de estrangulamento, compreendendo uma parte da carcaça (10, 13, 53) e uma parte da válvula (17, 18, 23) móvel em relação a essa parte. Transcorrem as seguintes etapas do processo: Em primeiro lugar ocorre a fundição por injeção da parte da carcaça (10, 13, 53) em uma primeira cavidade de um primeiro material sintético. A peça bruta pré-injetada (41) da parte da carcaça (10, 13, 53) obtida é transportada para uma segunda cavidade separada espacialmente da primeira cavidade. Na segunda cavidade ocorre a fundição por injeção da parte da válvula (17, 18, 23) móvel de um segundo material sintético (57), dentro da peça bruta pré-injetada (41) da parte da carcaça (10, 13, 53). Antes do transporte da peça bruta pré-injetada (41) para a segunda cavidade (42) ocorre um tratamento intermediário da peça bruta pré-injetada (41), para a influência do comportamento de vibração e, por conseguinte, para o ajuste visado das geometrias de fendas entre as partes (41; 17, 18, 23).
