Abstract

L'invention concerne un procédé de surveillance et/ou de commande et/ou de régulation de fonctions sur des machines de moulage par injection, au moyen de capteurs (7), notamment de capteurs de température et/ou de pression, qui surveillent une matière fondue dans au moins un canal de chauffe, une filière, une cavité ou analogue. Selon l'invention, lorsque la température et/ou la pression commence à augmenter, le capteur (7) déclenche un signal destiné à un processus de surveillance et/ou de régulation dans la machine de moulage par injection.
