Abstract

Se divulga un aparato de moldeo por inyección de canal caliente y el método de uso en el que se proporcionan galgas extensiométricas en las zonas de temperatura del aparato de moldeo por inyección de canal caliente y un controlador de canal caliente crea un perfil de tensión objetivo, detecta desviaciones del perfil de tensión objetivo en cualquier zona de temperatura en función de las lecturas de tensión proporcionadas por las galgas extensiométricas en cada zona de temperatura, y ordena la corrección de las desviaciones del perfil de tensión objetivo en cualquier zona de temperatura de desviación al ajustar el calor producido por un calentador o unos calentadores en la zona de temperatura de desviación. El perfil de tensión objetivo puede basarse en una mediana o un promedio de lecturas de tensión proporcionadas a lo largo del tiempo mediante las galgas extensiométricas en cada zona de temperatura. También se divulga un tubo hueco de instalación para colocar las galgas extensiométricas en el aparato de moldeo por inyección de canal caliente.
