ESPEARL is ball-shaped artificial sand made of Alumina, and can be repeatedly reused since it has better hardiness and durability compared to silica sand. For this reason, ESPEARL benefits not only the foundry industry, but also contributes to the preservation of natural sand resources in rapidly growing countries. Since ESPEARL has higher thermal conductivity and excellent chilling characteristics than other products, it can be used as a substitute for Zircon and Chromite.

   
ESPEARL’s round grain shape coupled with smooth surface ensures great collapsibility even with minimal resin usage. Hence the time required to burn out resin after/before shakeout is greatly reduced.

   
ESPEARL requires a minimal level of resin, greatly reducing gas defects. Its minimal thermal expansion rate results in reduced veining defects, leading to precision and quality casting results.

   
ESPEARL’s excellent chilling characteristics dramatically reduce the cooling time after pouring, leading to maximum production efficiency.

As the inventor of ESPEARL artificial foundry sand, we believe that all ESPEARL we sell should be completely recycled. Due to its superior hardness, more than 98% of ESPEARL is fully recycled, compared with only 85% or less of silica sand in shell mold process.
