Abstract
"MáQUINA PARA MOLDAR A INJEçãO MULTI-CAVIDADE E MéTODO DE MOLDAGEM POR INJEçãO CONTìNUA DE PRODUTOS EM TRêS CAMADAS", compreendendo uma máquina para moldar a injeção multi-cavidade, para moldagem em três camadas, tendo pinos alongados para jito de pino fixo ou jito de válvula. Cada pino alongado tem um furo longitudinal central, estendendo-se posteriormente desde sua extremidade frontal até um número de furos longitudinais que se estendem lateralmente. Um material de barreira de baixa viscosidade, tal como o EVOH ou náilon flui através desses furos até o jito que conduz até a cavidade. Isto permite co-injeção com pinos fixos e jitos fixos em uma configuração e mediante um jito de válvula em outra configuração.
