Our Nodularity Products


NAP-01 Nodularity

  • In-line installation

    Because 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 operation

    All the processes from polishing to nodularity determination are done automatically, except the initial test piece casting.

  • In-line determination

    Nodularity can be determined within 6 minutes at the minimum, and hence, quality judgment is done while the product is still in the production line.
