Abstract
SE DESCRIBEN UN METODO Y SISTEMA PARA INTRODUCIR FLUIDOS LOCALMENTE, TAL COMO UN GAS, EN UNA POSICION DETERMINADA, EN RESINA FUNDIDA CORRIENTE ABAJO DE UNA ABERTURA DE INYECCION DE RESINA PARA FORMAR UNA PARTE HUECA. EL GAS SE UTILIZA EN EL AREA LOCALIZADA PARA DISTRIBUIR LA RESINA FUNDIDA, PARA ELIMINAR EL MOLDEADO EN TENSION Y EVITAR LA FORMACION DE HUELLAS DE SUMIDERO EN LA PARTE DURANTE LA SOLIDIFICACION DE LA RESINA. UN DEPOSITO SUMIDERO FUERA DE LA CAVIDAD DEL MOLDE SE LLENA CON LA RESINA DURANTE LA INYECCION DE LA RESINA Y LUEGO EL GAS SE INTRODUCE EN EL DEPOSITO A TRAVES DE UNA ABERTURA PARA FLUIDO Y EN LA PARTE. EL DEPOSITO CREA UNA ENVOLTURA DE MATERIAL SOLIDIFICADO QUE ACTUA COMO UN CIERRE QUE IMPIDE LA FUGA DE GAS. UN CUERPO HUECO FORMADO SEGUN EL METODO Y EL SISTEMA INCLUYE UNA PARTE DE CUERPO HUECO SUSTANCIALMENTE CONTINUO, CON UNA ABERTURA PARA FLUIDO PARA COMUNICAR LA PARTE INTERIOR DE CUERPO HUECO CON EL FLUIDO INTRODUCIDO LOCALMENTE. EL CUERPO HUECO PROPORCIONA UN MULTIPLE DE GAS INTERNO Y MEDIOS PARA MAYOR INTEGRIDAD ESTRUCTURAL.
