Abstract

"PROCESSO PARA MOLDAR COMPONENTES DE GRANDEPORTE". Pelotas de plástico reforçado compreendem materialtermoplástico e partículas de reforço que são menores do que 15%de um volume total das pelotas, e pelo menos 40% tem umaespessura de menos do que 50 nanómetro. Um distribuidor 56 tempelo menos 2 registros de válvula espaçados 64 que são abertos efechados de maneira independente quando comandados por umcontrolador 68 para comunicar de maneira seletiva o distribuidorcom uma cavidade. Uma pressão de injeção primária é aplicada aomaterial pelota plastificado no distribuidor 56, para encher acavidade através de abertura e fechamento seq³encial dosregistros 64. Uma pressão de injeção secundária mais baixa éaplicada ao material no distribuidor, para encher continuamente acavidade. As registros são fechados para vedar o distribuidor dacavidade quando a cavidade está cheia. O material é mantido emcompressão dentro do distribuidor por meio das válvulas enquantoa cavidade está aberta, para impedir expansão do material.
