PROBLEM TO BE SOLVED: To reuse a mold release agent by recovering the agent the total of which has conventionally been discarded. SOLUTION: A recovering means 5 exclusive for the mold release agent is arranged just below metallic molds 1, 1 and the release agent coated with a spraying device 3 and dripped down, is held. After removing metallic burr, the release agent is collected into a recovering pit 10 and further, sent to a recovering mixed tank 16 through a recovering settle-down tank 14. In the recovering mixed tank 16, a concentration measurement is performed with an automatic concentration measuring instrument 17 using an ultrasonic densitometer, and the necessary amounts of components are supplemented from an original solution tank 21 and a water tank 22, and the release agent is again sent to the spraying device 3 from a supplying duct 86 as the regenerated solution having a prescribed component ratio.
