Abstract

Patente de Invenção: <B>"PROCESSO DE CONTROLE DE VáLVULA DE ESTRANGULAMENTO PARA A COEXTRUSãO DE MATERIAIS PLáSTICOS PARA MOLDAGEM E SEMELHANTE, E APARELHO DESTINADO à MESMA"<D>. Processo e coextrusor de curso de múltiplos plásticos, no que se refere à cavidades de moldagem por injeção, nos quais o extrusor é internamente provido entre as mesmas e ao longo das mesmas com um pino, tirante ou elemento restritor ou de estrangulamento que força os cursos combinados de material plástico, formados com um curso de núcleo interno encerrado nas camadas de curso externa e interna, nas camadas de curso de fluxo anular concêntrico correspondentes que são finalmente divididas transversalmente em direções opostas em uma cavidade aberta para o extrusor, e com o curso de núcleo em uma região de gradiente zero no perfil de velocidade de fluxo transversal dentro do extrusor e da cavidade.
