TOPMelt Quality Control > Quick Polisher

Automatic Cutiting, Automatic polishing and graphic analysis of nodularity for spheroidal graphite cast iron
Quick Polisher

  • Quick Polisher automatically tells you the nodularity of your cast iron melt within about 6 minutes after receiving a test piece cast by pouring your melt in a proprietary shell mold cup.

Features

In-line installation

Because of its dry system, NAP-02 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.
