PROBLEM TO BE SOLVED: To provide a long life weighing machine for molding material capable of further keeping the weighing accuracy in a weighing recessed part over a long period of time even after the projected part formed to the material inflow port of a casing is abraded when weighing work is repeatedly performed. SOLUTION: A first projected part 12, which is extended from the side wall of the material inflow port 4 of the casing 7 along the arcuate surface of a weighing rotor 11 having the weighing recessed part 10 formed thereto, is formed to a forward side wall at a time when the weighing recessed part 10 is revolved from the material inflow port 4 toward the material outflow port 5 and a second projected part 13, which is extended from the side wall of the material outflow port 5 of the casing 7 to an inside direction along the arcuate surface of the weighing rotor 11 having the weighing recessed part 10 formed thereto, is formed to the forward side wall at a time when the weighing recessed part 10 is revolved from the material outflow port 5 toward the material inflow port 4.
