Abstract

Un procedimiento para la fabricación de una cerda de polímeros termoplásticos por el método de moldeo por inyección, al inyectar bajo presión la masa fundida polimérica en un canal formador de cerdas de una longitud determinada y de un curso de sección transversal determinada a lo largo de este tramo, y en el que durante el procedimiento de moldeo por inyección, el aire es expulsado de este canal. Para fabricar cerdas por el procedimiento de moldeo por inyección que presentan un excelente comportamiento de flexión se propone regular el valor de la presión de inyección respecto del curso de la sección transversal del canal formador de las cerdas de modo tal que se produzca una corriente tangencial con una elevada velocidad del núcleo en el centro de la masa fundida polimérica y una gran acción tangencial debido a la fricción en las paredes de la masa fundida polimérica, con una pronunciada orientación longitudinal de las moléculas poliméricas, al menos en el área cercana a la pared de la masa fundida polimérica y esa corriente es mantenida a lo largo del canal, siendo que simultáneamente se expele el aire del canal en toda su longitud de modo tal que se ayuda a mantener la corriente tangencial. Además, se describe un dispositivo para llevar a cabo el procedimiento.
