Abstract

"DISPOSITIVO DE ENFORMAçãO DE OBJETOS EM MATéRIA PLáSTICA SOB ATMOSFERA INERTE". A invenção se refere a um dispositivo de produção de objetos em plástico por enformação sob atmosfera inerte, compreendendo uma moega, um parafuso sem fim e meios de enformação do polímero fundido. O dispositivo de injeção do gás inerte compreende um conduto de alimentação com gás (3), uma superfície de injeção do gás ao nível da parede da moega (1) e uma câmara de homogeneização que coopera entre a parede da moega (1) e o conduto de alimentação com gás. A extremidade do conduto de alimentação com gás voltado para a superfície de injeção é fechada e apresenta pelo menos uma abertura (33) o radial que permite uma ejeção do gás perpendicularmente a seu sentido de circulação no conduto.
