Ceramic foundry sand has the advantages of high temperature resistance, no crushing, no dust, spherical shape, high air permeability, good filling, and no harm of silica dust.


Characteristics


1. Low thermal expansion rate to ensure the accuracy of castings;


2. High refractoriness, high thermal conductivity, easy to collapse and not crack;


3. Good fluidity and air permeability, easy to fall out of sand after pouring;


4. Smooth surface, dense structure, saving adhesive


5. Good recycling performance and lower crushing ratio.
