Orange Polyurethane Screen with 0.3mm Aperture 1040x700mm High Wear Resistance for Fine Screening

Compatible Orange PU Screen 0.3mm Aperture ISO Certified. High-wear PU mesh screens are engineered for the toughest wet screening tasks, from coal washing to aggregate dewatering. Their 0.1-5.0mm mesh range adapts to diverse materials, while the 15mm±0.5mm thickness ensures durability under heavy loads. The industrial orange color (UV-resistant) stands out in busy mines, reducing the risk of misplacement.

The 0.075mm aperture High-Efficiency Polyurethane Urethane Screens working 6-12 months are designed to withstand the rigorous demands of mining operations. Made from high-quality polyurethane, these screens offer exceptional durability and wear resistance. They are ideal for separating and sizing minerals, aggregates, and other materials in mining and quarry applications.

• Combines flexibility with strength: tensile strength of ≥45MPa allows vibration absorption without tearing
• Extended service life of 6-12 months (double that of rubber alternatives)
• Square-round hybrid apertures minimize particle trapping
• Maintains 90%+ screening efficiency even with high-moisture materials
• Equipped with metal hooks for seamless integration into standard vibrating screens
• Custom sizes (like 700mm x 1040mm) available for OEM needs

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Surface Treatment (Optional): Anti-static coatings or custom-colored finishes are applied for specific industrial requirements, such as explosive environments or visual inspection needs.
7. Packaging & Logistics: Screens are packed in moisture-proof, shock-absorbent materials and labeled for traceability. Custom sizes and OEM branding are accommodated seamlessly.
