Abstract

"MéTODO E DISPOSITIVO PARA PRODUZIR CERDAS". Trata-se de um método para a produção de uma cerda a partir de polímeros termoplásticos através de moldagem por injeção, em que a massa de polímero fundido é injetada sob pressão em um canal de moldagem de cerdas com comprimento predeterminado tendo uma seção transversal predeterminada ao longo deste comprimento e o canal é dotado de sangria de ar para dar vazão ao ar durante a moldagem por injeção. Para produzir cerdas moldadas por injeção com excelente comportamento em flexão, a magnitude da pressão de injeção é ajustada na dependência da extensão da seção transversal do canal de moldagem de cerdas, tal que um fluxo cisalhante é gerado com alta velocidade de núcleo no centro do fluxo de massa de polímero fundido e grande efeito de cisalhamento devido ao atrito com a parede da massa de polímero fundido sob orientação longitudinal distinta das moléculas do polímero pelo menos na região da massa de polímero fundido perto da parede, que se mantém ao longo do canal, em que o canal tem o ar simultaneamente liberado através da sangria de ar ao longo de seu comprimento para suportar a manutenção do fluxo cisalhante. Um dispositivo para realizar o método também é descrito.
