Abstract

Sistemas y enfoques para controlar una máquina de moldeo por inyección que tiene un molde que forma una cavidad de molde y que se controla de acuerdo con un ciclo de inyección incluyen inyectar un polímero fundido en la cavidad del molde de acuerdo con el ciclo de inyección usando un tornillo que se mueve de una primera posición a una segunda. posición. Una vez completado el ciclo de inyección, comienza un perfil de recuperación en el que el tornillo se mueve a la primera posición. Usando un sensor, se mide al menos una variable durante el perfil de recuperación. Al menos un parámetro operativo de la máquina de moldeo por inyección se ajusta con base en la por lo menos una variable medida durante el perfil de recuperación.
