摘要： A manufacturing facility of a sintered product according to one aspect of the present disclosure includes: a molding apparatus configured to press-mold raw material powder containing metal powder to fabricate powder compacts; a marking apparatus configured to mark a product ID including a serial number on each of the powder compacts; a batch processing apparatus configured to perform a predetermined batch process on intermediate materials which are the powder compacts or sintered articles of the powder compacts; a reader apparatus configured to read the product ID of each of the intermediate materials loaded in a batch case of the batch processing apparatus; and a server apparatus configured to communicate with the apparatuses. The server apparatus includes: a communication unit configured to receive a read value of the product ID from the reader apparatus; and a control unit configured to specify a load position of each of the intermediate materials in the batch case based on the received read value.

摘要： A method for laser-marking an iron-based sintered body includes a first step of forming with a first laser beam a plurality of dotted recesses with a predetermined depth in an identification mark area of a surface of an iron-based sintered body, and a second step of flattening with a second laser beam the surface within the identification mark area other than the dotted recesses. The first laser beam has an irradiation energy per unit area greater than an irradiation energy per unit area of the second laser beam.
