Abstract: A method of manufacturing a metal product comprise forming a base region on a surface of a metal member by repeatedly scanning along a predetermined first direction while irradiating the surface of the metal member with a base laser beam over a first set of rows. The method further comprises forming a marking by repeatedly scanning along a predetermined second direction while irradiating the surface of the metal member with a marking laser beam over a second set of rows. The second direction is different from the first direction. An identification code having a predetermined pattern comprises a combination of the base region and the marking.

Abstract: A method of manufacturing a metal product includes forming a first identification code onto a surface of a metal member with a laser beam, the first identification code being readable under a first reading condition, and heating the metal member on which the identification code is formed. The method further includes reading the first identification code with a reading device, and forming a second identification code onto the surface of the metal member subsequent to the heating with a laser beam based on the first identification code which is read with the reading device. The second identification code is readable under a second reading condition different from the first reading condition.

Abstract: This disclosure relates to a method of manufacturing a laminated core including a plurality of poles arranged side by side in a circumferential direction, each pole having three or more magnet housing holes and magnets housed in the magnet housing holes. The manufacturing method includes: a step of preparing a lamination having the magnet housing holes; a step of injecting sealing resin into a pair of magnet housing holes arranged at symmetric positions with respect to a line extending in a radial direction of the lamination, with the magnets being disposed in the pair of respective magnet housing holes; and a step of injecting sealing resin into another magnet housing hole, with the magnet being disposed in the magnet housing hole.
