La présente invention concerne un système d'alimentation et de circulation d'un agent démoulant recyclable pour la coulée sous pression et, plus spécifiquement, un système d'alimentation et de circulation d'un agent démoulant recyclable pour la coulée sous pression qui : permet de recycler pour la coulée sous pression, un agent démoulant qui a été raffiné par élimination d'impuretés apparues au cours d'un processus, l'agent démoulant étant utilisé pour améliorer la capacité de démoulage d'un produit de coulée à partir d'un moule lors de l'injection pendant la coulée sous pression ; détecte le niveau d'eau d'un réservoir de stockage dans lequel l'agent démoulant est stocké, et ajoute automatiquement un nouvel agent démoulant dans le cas où le niveau d'eau détecté est faible ; et coupe l'alimentation et permet la circulation dans le cas où le niveau d'eau du réservoir de stockage est détecté comme étant au maximum. Le système d'alimentation et de circulation d'un agent démoulant recyclable pour la coulée sous pression est destiné à recycler un agent démoulant par élimination d'impuretés contenues dans l'agent démoulant employé dans la coulée sous pression, et comprend : une unité d'écrémeur (100) ; une unité de tube d'alimentation en agent démoulant recyclable (200) ; une paire de réservoirs de stockage (300) ; une unité de soupape à trois voies (400) ; une unité de tube de recirculation (500) ; un réservoir d'injection (700) ; une unité de pompe d'injection (800) ; une unité de pompe de dosage (900) ; une unité de pompe d'alimentation en agent démoulant recyclable (1000) ; une unité de pompe de dérivation (600) ; et un contrôleur (1100).
