Precision Casting Sand For Casting High Temperature Resistant Non-Stick Sand
Introduction
Our company supplies jewel sand (jewelry sand, fused ceramsite, and ceramsite sand). Our products are of reliable quality and are widely used in various casting methods (investment casting, solid mold casting, and lost foam casting). They are a new type of raw sand for precision casting, coated sand, and self-hardening sand. They are also used for shot blasting (for aluminum, copper, and steel castings). Made from high-quality aluminum ore through high-temperature calcination, electric melting, and high-pressure aerosol spraying, this product offers a significantly better price-performance ratio than zircon sand and chromite sand. In particular, it exhibits low expansion, resists sintering, pulverization, cracking, and sand adhesion (eliminating negative impacts on casting quality), exhibits excellent regeneration properties, and improves casting yield.
Product Features of Casting Sand
Its low thermal expansion coefficient rivals that of zircon sand. Using it to create molding sand eliminates expansion defects in castings. Its spherical shape provides excellent fluidity and breathability, while its smooth surface and dense structure ensure uniform adhesive coverage. Baozhu Sand is a neutral material, compatible with both acidic and alkaline adhesives, offering excellent recyclability and cost-effectiveness. Compared to chromite sand and zircon sand, its price is only 30-50% of theirs. Furthermore, due to its spherical shape and reduced surface area, the amount of resin required can be reduced by 30-50%, and the water glass addition limit is ≤4%. This reduces casting defects associated with adhesives and improves the yield rate of castings.
