Polyurethane Fine Mesh Screen 0.045mm for High-Purity Silica, Orange, High Wear Resistance

PU Fine Mesh Screens, crafted from high-quality polyurethane, excel in precision separation for industries like silica sand processing and gold ore concentration. With mesh sizes as fine as 0.045mm (tolerance ±0.005mm), they deliver accurate classification of ultra-fine particles—critical for producing high-purity materials. Their red or orange color options (customizable on request) aid in visual inspection, while the 1040mm × 700mm standard size fits most vibrating screens, with custom dimensions available.

• Superior abrasion resistance, outlasting woven metal meshes by 4-10 times
• Excellent performance in wet sieving applications
• Anti-blinding design prevents clogging, even with sticky materials
• Reduced downtime for cleaning and maintenance
• Tool-free installation with polyurethane or metal hooks (under 15 minutes per panel)
• Certified to ISO 9001 and CE standards
• Suitable for both wet and dry screening applications
• Ideal for mineral processing and industrial wastewater treatment

• Material Preparation: High-grade polyurethane raw materials, including pre-polymers and curing agents, are meticulously selected based on abrasion resistance and elasticity requirements. Additives such as UV stabilizers and anti-aging agents are blended to enhance longevity in harsh environments.
• Mold Design & Fabrication: Precision CNC-machined molds are crafted from stainless steel or aluminum, incorporating the exact aperture geometry (e.g., 0.045mm wedge-shaped slots). Mold surfaces are polished to a mirror finish to ensure smooth demolding and dimensional accuracy.
• Casting & Curing: The liquid polyurethane mixture is vacuum-degassed to eliminate air bubbles. It is then poured into preheated molds and subjected to controlled-temperature curing (80-120°C) in hydraulic presses. This step ensures uniform density and structural integrity. Post-curing thermal treatment further enhances tensile strength and chemical resistance.
• Demolding & Trimming: Cured screens are carefully demolded, and excess flash is removed using laser trimming or precision cutting tools. Edge sealing is applied to prevent delamination during high-frequency vibrations.
• Quality Control: Aperture Verification: Laser scanners measure aperture sizes (e.g., 0.045mm ±0.005mm) and open area ratios (35%-40%). Durability Testing: Simulated high-frequency vibration cycles (up to 3,600 RPM) assess fatigue resistance. Material Certification: Shore hardness (85-95A), tear strength, and chemical compatibility are validated per ISO 9001 standards.
• Surface Treatment (Optional): Anti-static coatings or custom-colored finishes are applied for specific industrial requirements, such as explosive environments or visual inspection needs.
• Packaging & Logistics: Screens are packed in moisture-proof, shock-absorbent materials and labeled for traceability. Custom sizes and OEM branding are accommodated seamlessly.
