Abstract

"CANAL PARA MOLDAGEM POR INJEçãO". A presente invenção se refere à estrutura de um canal interno para moldagem por injeção, o qual diminui uniformemente a temperatura do composto injetado à medida em que este composto flui a partir da entrada para injeção para abertura de gotejamento únicas ou múltiplas nos ingressos para as cavidades de molde únicas ou múltiplas. O canal interno apresenta duas séries opostas de canais paralelos formados no interior do canal para fins de mistura do composto à medida em que este flui através do canal.
