LABORATORY TEST EQUIPMENTS

There are many of factors effecting the quality of sand in foundries. Besides content of the melt, foundry sand quality is an critical input to reach desired quality in te product. Sand preperation must be done properly and surely must be controlled well. That’s why foundry sand testing equipments take an important role in that.

Here are some of the critical characteristics of molding sand which must be checked:

  1. AFS granular size of molding sand
  2. Moisture amount of the sand
  3. Permeability of the sand
  4. Total clay amount (dust content) of the sand
  5. Active clay amount
  6. Compressive strenght
  7. Breaking strenght
  8. Hardness of molding sand
  9. Compactability of the sand
  10. Combustion loss
  11. Shear strenght
