Zircon Flour For Foundry

Ideal Choice for Foundry Face Coat - Zircon Flour for Foundry

• Zircon Flour for Foundry is a core coating raw material specially developed for investment casting, sand casting and precision casting industries. With 24 years of experience in the foundry industry, we deeply understand what a good zircon flour means to casting quality - it directly determines the surface finish, dimensional accuracy and yield of castings. That is why we set nearly stringent quality control standards for Zircon Flour for Foundry: every batch of products undergoes strict particle size testing to ensure the D50 value is stable within the specified range, with a 325-mesh passing rate of over 98%, so that your coating formula does not need frequent adjustment and always maintains optimal coating performance.
• The core value of Zircon Flour for Foundry lies in its excellent thermal stability and chemical inertness. During the pouring process of high-temperature molten steel above 1500℃, the zircon flour coating can effectively block the chemical reaction between molten metal and the mold shell, preventing defects such as sand burning and burrs. Our zircon flour is made from Australian imported high-purity zircon sand through multiple processes such as ultra-fine grinding, precise classification and high-efficiency iron removal, with ZrO₂ content steadily above 65% and Fe₂O₃ content controlled below 0.1%. Compared with ordinary foundry zircon powder on the market, our Zircon Flour for Foundry has higher whiteness, more concentrated particle size distribution and better suspension property. The prepared coating has uniform brushing and good leveling property, and the coating is dense and smooth after drying. Well-known domestic sanitary ware brands such as JOMOO and ARROW have been using our products in their foundry workshops all year round, which is the best proof of our quality.

We fully understand that different foundry processes have vastly different requirements for zircon flour. Therefore, we provide comprehensive OEM/ODM customization services. We can adjust parameters such as particle size distribution, chemical composition and surface treatment methods according to your technical drawings or sample requirements to tailor the most suitable product for you. Whether you need a narrower particle size distribution range, a specific D50/D90 ratio, or special surface modification treatment, our R&D team can deliver it for you. The development cycle of customized samples is only 15-20 days, enabling you to verify and put into production quickly.

Our quality control runs through the entire production process. Starting from raw material incoming, every batch of zircon sand undergoes full-element analysis by spectrometer to ensure raw material quality meets the standard. During production, samples are taken every 2 hours to test key indicators such as particle size, whiteness and moisture. Before delivery, final full-item inspection is conducted to ensure every bag of products meets the standard. We support third-party inspection and can provide batch test reports according to your requirements. Our 24-year record of zero major quality accidents is the best testimony to our quality commitment.

We provide not only products, but a complete set of technical solutions. Before sales, our technical team will communicate with you in depth to understand your process requirements and recommend the most suitable product specifications. During sales, we will update the order production progress in real time, and provide one-stop services such as product testing data, loading and customs declaration. After sales, our technical experts will answer any questions you encounter during use online, providing continuous technical guidance and follow-up services. If you encounter any problems during use, we promise to respond within 24 hours and provide solutions within 48 hours.
