Abstract
Patente de Invenção: "ARTIGOS DE CAMADAS MúLTIPLAS DE MOLDAGEM USANDO TéCNICAS DE CO-INJEçãO". Um molde de co-injeção e um método para simultaneamente produzir uma pluralidade de artigos de multicamadas compreendendo: uma estrutura de molde que define uma pluralidade de cavidades de molde; uma primeira fonte de suprimento para suprir quantidades medidas de um primeiro material de moldagem; uma segunda fonte de suprimento para suprir quantidades medidas de um segundo material de moldagem; um sistema de transportador quente em comunicação com as primeira e segunda fontes de suprimento para transportar as quantidades medidas do primeiro e segundo materiais separadamente para uma região próxima a cada uma das cavidades; a região compreendendo ter uma passagem de pino controlada que leva a uma cavidade próxima por meio de uma porta tendo a mesma seção transversal que a passagem, o pino expulsando material da passagem e provendo compactação de cavidade.Invention Patent: "MULTIPLE MOLDING LAYER ARTICLES USING CO-INJECTION TECHNIQUES". A co-injection mold and a method for simultaneously producing a plurality of multilayer articles comprising: a mold structure that defines a plurality of mold cavities; a first source of supply for supplying measured quantities of a first impression material; a second supply source for supplying measured quantities of a second impression material; a hot conveyor system in communication with the first and second sources of supply to transport the measured quantities of the first and second materials separately to a region close to each of the cavities; the region comprising having a controlled pin passage that leads to a nearby cavity by means of a door having the same cross section as the passage, the pin expelling material from the passage and providing cavity compaction.
