DEMECH is a pioneer in the manufacture of Cast Basalt tiles and cylinders in India since 1987.
After selective quarrying, the volcanic rock is melted at a temperature of around 1500ºC and cast into molds or spun into cylinders. The castings so produced are then subjected to heat treatment cycles in special kilns to produce re-crystallized basalt. The product thus produced inherits inertness of parent material. Its micro crystalline, non-porous texture being denser and more homogenous than raw basalt, acquires exceptionally high abrasion resistance.
