Coated Sand
Gongyi City Hong The Refractory Material Co., Ltd. produces resin‑coated sand where natural quartz grains are enveloped by a solid phenolic resin layer, creating a material that resists high winds, exhibits low gas evolution and maintains dimensional stability during casting. The manufacturing process can involve a cold‑ethanol method or a thermal melt technique, both yielding a uniform shell that improves casting surface finish and reduces expansion. Originating from Henan Province, China, the coated sand is positioned for high‑precision cast iron and non‑ferrous metal components.
Typical formulations use quartz sand as the base, novolak phenolic resin as the binder, urotropine as a blowing agent and calcium stearate as a release enhancer. Grain sizes are generally between 0.2 mm and 0.5 mm, giving good flow and packing density, while the cured sand attains a bulk density of about 1.5 g/cm³. Various grades are offered, including ordinary, high‑strength low‑gas, high‑temperature and easy‑collapsibility types, each tailored to specific casting requirements.
Foundry customers producing automotive engine blocks, hydraulic components, tractor parts and complex thin‑wall castings often source this material. The supplier provides flexible minimum order quantities and ships the sand in bulk bags or 1‑ton flexible sacks under CIF or FOB terms. Payment can be arranged via L/C or T/T, allowing buyers to align financing with their procurement cycles.

Sourcing Coated Sand from Gongyi City Hong The Refractory Material Co., Ltd. - China Import Guide
Prior to ordering, confirm the resin type, additive package and grain‑size distribution to ensure the sand meets the mechanical and thermal requirements of your casting process. Request test reports for tensile strength, moisture content and gas evolution to validate performance against your specifications.
Discuss logistics early: agree on Incoterms such as CIF or FOB, clarify the expected lead time for coating and shipment, and verify the payment terms (L/C or T/T) that suit your financing. Make sure the supplier provides clear documentation of shipping marks, bulk‑bag sealing procedures and any required customs documentation for import into your country.
Implement a quality‑control plan that includes a pre‑shipment inspection or third‑party testing of key parameters such as grain size, bulk density and cured strength. Obtain certificates for resin composition, fire resistance and any relevant environmental standards, and retain these documents for traceability throughout the production run.
