Frame Extruder Screen Packs
Frame Extruder Screen Packs Manufacturer | Multi-Layer Framed Extruder Screens
Frame Extruder Screen Packs are rigid, pre-framed filtration units designed for high-precision polymer melt filtration in plastic extrusion, blown film, sheet production, compounding, rubber extrusion, and various melt-processing applications. Each framed screen combines multiple layers of woven wire mesh, securely welded or spot-welded inside a metal frame to ensure dimensional stability, uniform filtration, and easy installation.
Unlike loose wire mesh screens, framed extruder screens maintain their shape under high pressure and temperature, preventing mesh deformation and improving overall extrusion consistency. They are widely used in extruders equipped with manual, hydraulic, and continuous screen changers, offering reliable contaminant removal for polymers including PE, PP, PET, PS, PVC, PA, EVA, rubber compounds, adhesives, and more.
With optimized rigidity, precise micron control, and excellent mechanical strength, Frame Extruder Screen Packs help improve melt purity, protect extrusion equipment, extend service life, and ensure stable product quality.
Advantages of Frame Extruder Screen Packs
1. Enhanced Structural Stability
The metal frame eliminates screen distortion, ensuring precise mesh alignment and consistent micron rating even under high extrusion pressure.
2. Easy Handling and Quick Replacement
Pre-framed screens fit directly into screen changers without additional preparation, reducing downtime and streamlining maintenance.
3. Superior Filtration Efficiency
Available in multiple-layer combinations (2–7 layers), including fine mesh, support mesh, and reverse Dutch weave for precise melt filtration and improved contaminant capture.
4. High Temperature and Corrosion Resistance
Manufactured from stainless steel, nickel alloys, galvanized steel, or custom metals, providing long service life in demanding processing environments.
5. Customizable for All Extrusion Equipment
Round, rectangular, oval, and special shapes available for all major extruder brands, with custom frames, mesh counts, and thickness options.
6. Improved Productivity
Stable screen structure minimizes pressure fluctuations, reduces extruder wear, and supports higher output and more stable melt flow.
