Sand Lab

Sand Analysis

Our Kohler Sand Lab checks the sand for proper formulation and quality limits during the process, which is why Kohler can make and use only A-1 molds for production.

To ensure consistent quality, our Sand Lab analyzes: 

  • Moisture 

  • Green strength

  • Deformation 

  • Screen distribution

  • Wet tensile 

  • pH

  • Compatibility 

  • Permeability

  • Methylene blue  

  • Mold hardness

  • Incoming material
