Products Description
Extruder screens, also known as melt filters or polymer filters, are critical components in plastic, rubber, and fiber extrusion processes. Designed to remove contaminants such as dirt, metal shavings, and undispersed additives from molten materials, they ensure consistent product quality, protect extrusion equipment, and reduce downtime. Our screens combine advanced materials, precise engineering, and customizable designs to meet the rigorous demands of modern manufacturing.
Key Features for Superior Filtration
1. Premium Materials for Durability & Corrosion Resistance
- Stainless Steel Screens: Available in SS 304, SS 304L, SS 316, and SS 316L grades, offering excellent resistance to chemicals, high temperatures (up to 800°C), and abrasion. Ideal for general plastics (PP, PE, PVC), rubber, and non-woven fabric extrusion.
- Nickel Alloy Screens: Including Inconel, Monel, and Hastelloy, designed for extreme environments with exposure to sulfuric acid (H₂SO₄), hydrofluoric acid (HF), saltwater, or high-temperature applications (up to 1200°C). Perfect for chemical fiber, masterbatch, and recycled material processing.
2. Precision Mesh Sizes for Targeted Filtration
- Mesh Range: 4 mesh (4750μm) to 500 mesh (25μm), with custom microns down to 5μm for ultra-fine filtration.
- Weave Types: Plain weave for balanced flow & particle retention, twill weave for higher strength, and Dutch weave for precise control of sub-micron particles.
- Application Matching: Coarse meshes (4-40 mesh) for pre-filtration in recycling; medium meshes (60-200 mesh) for standard plastic extrusion; fine meshes (200-500 mesh) for medical-grade polymers, optical fibers, and high-clarity films.
3. Flexible Configurations for Every Extrusion Setup
- Single-Layer Screens: Lightweight, cost-effective, and easy to install, suitable for low-contamination applications like hot melt adhesives or reagent filtration.
- Multi-Layer Screen Packs: Engineered with graded meshes (e.g., 200-100-200 mesh) to optimize flow rates and particle capture. The symmetrical design prevents misinstallation and ensures uniform pressure distribution, ideal for precision extrusion lines.
- Custom Shapes & Sizes: Circular, rectangular, oval, kidney-shaped, or fully custom forms to fit any extruder model (compatible with brands like Brabender, Coperion, JSW). Edge treatments include spot-welded, aluminum framing, or stainless steel reinforcement to prevent bypass leakage.
4. High Temperature & Pressure Resistance
- Withstands operating pressures up to 300 bar and temperatures up to 1200°C (depending on material), ensuring reliability in high-viscosity applications like PVC compounding or rubber calendering.
