Sand Lab

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
