Abstract

PURPOSE: To decrease the number of metal molds, and to eliminate the unevenness, etc. of the length of segments while obtaining the commutator of high performance, by molding segment bars or segment fittings by heating and pressurizing conductive, metallic material powder.
CONSTITUTION: When forming dovetail type segment bars, etc., a lower metal mold 5 for sintering and molding is heated by means of a heater 6, conductive, metallic material powder, such as, arborescent, electrolytic copper powder 7, etc. is filled into a inserting hole by force, whose sectional shape is as shown in a, a force piston 4 is inserted into the inserting hole, and the whole is pressurized and molded in an atmosphere of hydrogen gas, etc. Thus, metal molds can be diminished, the shortening of a process of manufacture and the unevenness, etc. of the length of segments are eliminated, and the commutator with excellent performance can be obtained.
