Advanced Ceramic Media
& Casting Precision

Redefining the standards of non-metallic mineral products for modern industrial foundries.

Our Ceramic Foundry Sand occupies a leading position in the non-metallic mineral industry, providing a sustainable and high-performance alternative to traditional silica sand. By integrating precise mineralogical compositions of Mullite and Corundum, we enable foundries to execute complex applications of sand casting with unprecedented accuracy and reduced thermal expansion.

The technical advantage lies in our spherical grain geometry, which significantly enhances collapsibility and separation from cast parts. This innovation leads to a substantial reduction in scrap rates and resin consumption (up to 30-50%), while offering a safer, silicosis-free environment for operators compared to traditional quartz-based sands.

The Three
Core Pillars of Excellence

Engineered for durability, precision, and environmental sustainability in every grain.

01

Thermal Stability

Optimized for extreme temperature resistance to prevent mold deformation.

  • High Refractoriness: Up to 1800°C for heavy-duty casting.
  • Low Expansion: 4.5-6.5x10-6/k ensures tight tolerances.
  • Conductivity: Lower thermal conductivity for better mold performance.
02

Morphological Precision

Spherical grains engineered for superior flow and separation.

  • Spherical Shape: Easier shake-out and reduced casting defects.
  • Grain Coefficient: Consistently ≤1.1 for uniform packing.
  • Surface Area: Lower specific surface area reducing binder needs.
03

Environmental Safety

Eco-friendly alternative to hazardous silica minerals.

  • Non-Toxic: Zero risk of silicosis for plant workers.
  • Resin Efficiency: 30-50% reduction in chemical binder usage.
  • Sustainable: Longer work life and recyclable properties.

Frequently Asked
Questions

Expert answers to technical inquiries regarding ceramic sand casting.

01

How does ceramic sand improve the applications of sand casting?

Ceramic sand offers lower thermal expansion and higher refractoriness than silica, reducing casting distortions and allowing for higher temperature alloys to be cast with superior precision.

02

Can it be used with both acid and alkali resins?

Yes, as a neutral material, our ceramic foundry sand is compatible with both acid and alkali resin systems, making it versatile for various binding processes.

03

What are the benefits of spherical grains over angular grains?

Spherical grains provide better flowability, denser packing, and significantly easier separation (collapsibility) from the cast part, reducing post-processing labor.

04

Is it truly a safe alternative to silica sand?

Absolutely. Unlike silica sand, ceramic sand does not contain free crystalline silica, eliminating the risk of silicosis and ensuring a healthier work environment.

05

Can particle size be customized?

Yes, we provide a wide range of particle distributions from 45μm to 2000μm, and can customize the mesh size to match your specific molding requirements.

06

What is the typical resin saving achieved?

Depending on the application, most foundries report a reduction in resin usage of 30% to 50% due to the optimized specific surface area of our spherical grains.
