Industry Grade 10 Mesh Water Washed Foundry Fine Silica Sand with 99.8% SiO2 Content for Casting

Product Specifications

Industry Grade 10 Mesh Water Washed Foundry Fine Silica Sand with 99.8% SiO₂ Content (HS Code: 2505100000)

Foundry operations across Asia-Pacific often face critical challenges with silica sand—impurities causing casting defects, inconsistent particle sizing leading to mold instability, and delayed deliveries disrupting production schedules. In our 10+ years serving foundries in Southeast Asia and multinational procurement centers, we’ve witnessed how substandard silica sand can increase scrap rates by up to 15% and extend production cycles by weeks.

Stable Supply of High-Purity Foundry Silica Sand

Our foundry silica sand addresses these pain points through rigorous water washing and classification processes, ensuring 99.8% SiO₂ purity and consistent 10 mesh particle distribution. As a leading chemical trade hub, we leverage Hong Kong’s free trade policies and bonded warehousing capabilities to maintain 5000kg/day production capacity, supporting just-in-time delivery for manufacturing enterprises in Southeast Asia.

Key Applications in Foundry Industry

This water washed foundry sand is specifically engineered for precision casting processes, including green sand molding, core making, and investment casting. Its granulated shape and natural color provide optimal flowability and thermal stability, making it suitable for casting iron, steel, and non-ferrous alloys in automotive, machinery, and aerospace component manufacturing.

Critical Specifications for Foundry Performance

The 99.8% SiO₂ content minimizes chemical reactions with molten metals, reducing gas porosity and surface defects in castings. The 10 mesh particle size (16*30 specification) ensures proper permeability and mold strength, balancing sand compaction with gas escape during pouring. Our water washing process removes clay and fines, preventing mold cracking and ensuring dimensional accuracy in complex cast geometries. Consistent particle shape and size distribution also enable repeatable mold performance, critical for large-scale production runs.

Quality Assurance and Production Benefits

Using our high purity foundry fine silica sand translates to tangible production benefits: reduced scrap rates, shorter casting cycles, and lower post-processing costs. Compliant with ISO 9001 quality standards, our sand meets strict industrial requirements for heavy metal content and particle uniformity, ensuring compatibility with international foundry specifications. Unlike low-grade alternatives that risk casting defects and production delays, our stable supply chain and batch-to-batch consistency eliminate unexpected production disruptions.

Our Commitment to Quality and Reliability

Certificate of Analysis & Documentation

Each delivery includes a batch-specific COA and MSDS, providing detailed safety and handling information. For critical applications, additional testing reports (such as particle shape analysis or chemical composition breakdown) can be requested prior to order confirmation. All documentation is available in English to facilitate international trade and customs clearance processes.

Storage & Handling

• Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
• Keep away from incompatible materials, food and feed sources.
• Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
• Follow good industrial hygiene practices. Avoid inhalation and skin contact.
• Refer to MSDS for detailed storage and safety instructions.
