Abstract

EL INVENTO CONSISTE EN UN PROCEDIMIENTO PARA LA FABRICACION DE UN ARMAZON DE POLIMEROS. EL ARMAZON ES FORMADO POR EXTRUSION Y CONSTA DE UN PEQUEÑO MOLDE CON AL MENOS UNA PARED ESPONJOSA. EL PEQUEÑO MOLDE, TODAVIA EN ESTADO TERMOPLASTICO, ENTRA EN LA MAQUINA DE FORMACION DONDE VA DIRECTAMENTE A SU DISPOSITIVO DE SEPACRACION,LA PARED ESPONJOSA ES SOMETIDA A UN DISPOSITIVO DE GRANULACION, EL MOLDE TOMA SU FORMA DEFINITIVA Y DESPUES DE SER ENFRIADO ES EXTRAIDO DE LA MAQUINA PARA SER UTILIZADO COMO MOLDE. EJERCIENDO PRESION QUE TENDRIA EFECTO SOBRE LA ZONA SUPERFICIAL DEL ARMAZON, EL PEQUEÑO MOLDE PODRIA LLEGAR A ALCANZAR LOS LIMITES DE LA MAQUINA DE FORMACION
