Masterful craftsmanship and quality control that build trust
Building global trust through “precision” and “sincerity.” Matsumoto Kosan’s craftsmanship and commitment to quality.
Pursuing invisible precision
Matsumoto Kosan’s craftsmanship is supported by the delicate processing techniques of our skilled technicians and our own special cutting tools.
Our flexible system allows us to handle everything from prototypes to mass production, and the ability to “cut out” anything precisely from a single item to large lots, make invisible precision of commitment become shapes.
Processing techniques by veteran technicians
In-house development of special cutting tools
Development capabilities that support everything from the prototype stage
Ability to “carve out” anything from small lots to mass production
Measurement technology that achieves an error of 0.1μm
Matsumoto Kosan’s quality assurance system makes full use of cutting-edge inspection technology, including high-precision measuring equipment that enables measurements with an error level of 0.1μm, and 100% appearance inspection that combines visual inspection with AI image recognition. We strive for zero defects even amid high-mix mass production, and by making the inspection process in-house compliant with ISO and IATF visible, we always achieve consistent quality.
