Abstract

BOCAL DE CO-INJEçãO ESCOADOR A QUENTE COM CANAIS DE MATERIAL FUNDIDO SEPARADOS TERMICAMENTE Aparelho e método de bocal de moldagem por co-injeção (16) inclui a estrutura e/ou etapas onde um primeiro canal de material fundido de bocal (202) é mantido termicamente separado de um segundo canal de material fundido de bocal (203). Preferivelmente, os sulcos no corpo de bocal (213,214) ou um tubo de bocal separado (103) mantêm os primeiro (202) e segundo (203) canais de material fundido de bocal termicamente separados. Preferivelmente, uma ponta de bocal altamente termicamente condutora (206) é acoplada de forma removível ao corpo do bocal (200) e incluí primeiro (202) e segundo (203) canais de material fundido de ponta de bocal que se unem antes da porta do molde.
