Our Nodularity Products

NAP-01 Nodularity

  • In-line installationBecause of its dry system, NAP-01 can be installed in a production line. Because of its automatic system, personal bias is avoided both in the polishing step and the structural analysis step. Further, analysis result is obtained within a few minutes and hence, can be immediately fed back to the melting operation.
  • Full automatic operationAll the processes from polishing to nodularity determination are done automatically, except the initial test piece casting.
  • In-line determinationNodularity can be determined within 6 minutes at the minimum, and hence, quality judgment is done while the product is still in the production line.

TEC – 21

Conventional CE-meters only determine chemical compositions and are unable to respond to advanced level of such technical requirements as thin-walled castings, complicated shapes, necessity of avoiding hard layers, or materials for high functions. This equipment was developed as a quality control tool on the melting floor that will greatly help production of castings for high technical requirements

SG Analyzer


  1. Graphite number and shape are automatically identified.
  2. Inclusions or flaws other than graphite are automatically omitted from analysis.
    (Judgment of omit or not is done automatically according to the size of inclusion or flaw.)
  3. Ferrite ratio and pearlite ratio are measured.
