PROBLEM TO BE SOLVED: To provide a method for supplying coating material and its device which stabilizes the film thickness of the coating material and has excellent product quality and also, can improve adhesion when a product is cast in the other product. SOLUTION: A nozzle 20 constituted of a coating material supplying machine 22 is advanced into the inner part of a metallic mold body 12 by rotating the metallic mold body 12 and the coating material is supplied into the nozzle 20 from a Mono pump 34 (trade name) through a regulator 36, a flow-meter 38, a comparator 40 and a two-way valve 42. Further, a feedback signal of the flow-meter 38 is transmitted to the comparator 40 to compare the flow rate signal transmitted from the flow-meter 38 with a set value, and a flow rate difference signal is supplied into the regulator 36 to control the coating material supplying quantity with the regulator 36 so as to eliminate the flow rate difference.
