Artificial sand for casting - Lunamos®

Lunamos is an artificial sand with a high sphericity and a smooth surface created by Kao's unique production technology.

Features of EG Runner®


  • With its high sphericity and surface smoothness, the amount of resin added can be reduced, resulting in excellent sand fluidity and mold loading.
  • Composed of mullite, Lunamos demonstrates high fire resistance, reducing burn-on defects.
  • A low expansion coefficient results in enhanced dimensional accuracy.
  • Excellent abrasion and crush resistance results in less dust.
  • Is compatible with cast iron, cast steel and light alloy mold materials and can also be used for special precision casting molds.
