Abstract

Un método de control para un sistema de moldeo por inyección que tiene un extrusor, alimentar el material de forma continua a un acumulador, fraccionar el material de forma intermitente a un dispositivo de inyección, en donde el método de control está configurado para accionar el extrusor a una alta velocidad o una baja velocidad, respectivamente, la alta velocidad y la baja velocidad que define un intervalo de velocidad de extrusor, el método que comprende adquirir un valor para un cambio de posición real para el acumulador (?POSACT), comparar el valor para el cambio de posición real (?POSACT) con un valor previsto para el cambio de posición (?POSPRED) ajustar una velocidad de extrusor con base en un resultado de la comparación.
