Ceramic foundry sand, also named as ceramsite, cerabeads, is good artificial ball sand foundries. Compare with Silica sand, it has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, high resistance to wear, high reclamation rate, it could reduce the resin addition and coating amount, increasing your castings yield.
Kaist Ceramic foundry sand has highly cost-effective on sand molding foundry.
