Photography of the metal structure, Storage, Spheroidal Graphite measuring equipment by the image analysisr



  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.

A concrete example

After automatic start

1. Window for the software of two button system

Initial calibration

2. Macroscopic check on the setting of nodularity etc.

3.During automatic analyzing

4.After analysis and evaluation

5.Process of work is Put a test specimen on the examine mount.Push the red button twice, while observing an image (1st push is confirming of the image and 2nd push is set)

6.Take in the images needed (Max.10)
Screen image shifts to the window (during automatic analyzing), when the black button is pushed.

Setting change window


  • Maximum diameter for omitting
  • Binarization, manual auto change

Master maintenance

9. Master for customer

10. Master for material

11. Master for products and item No.

*If master maintenance is registered in advance, the work for lot registration may become easy and simple.
