Pleated Extruder Screen Packs
Pleated Extruder Screen Packs | High-Efficiency Polymer Filtration Solutions
Pleated Extruder Screen Packs are an advanced filtration solution for polymer extrusion processes. Designed with a pleated structure, these screens increase the filtration surface area while maintaining a compact size, allowing for higher throughput and longer service life compared to traditional flat or welded screens. Pleated screens effectively remove contaminants, gels, and other impurities from polymer melts, ensuring a high-quality, consistent output. They are compatible with various thermoplastics, including polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and engineering plastics.
Pleated Extruder Screen Packs are widely used in industries such as plastics, packaging, automotive, and medical device manufacturing. Their modular design allows easy installation, maintenance, and replacement, reducing downtime and operational costs.
Advantages of Pleated Extruder Screen Packs
- Enhanced Filtration Efficiency
The pleated design significantly increases the effective surface area of the screen, allowing more melt to pass through while capturing fine contaminants. This ensures fewer impurities in the final product, reducing defects such as gels, black specks, and uneven surface finishes. - Longer Service Life
The combination of durable filtration mesh and pleated construction extends the operational life of the screen pack. Fewer replacements are required, minimizing operational interruptions and reducing production costs. - Consistent Melt Pressure
Pleated screens distribute melt flow evenly across the filtration surface, maintaining stable pressure during extrusion. This reduces stress on extruder components and ensures uniform polymer output. - Compact and Space-Saving Design
Pleated screen packs offer large filtration areas within a compact form factor. They can fit into limited extruder spaces without compromising filtration performance, making them ideal for modern extrusion equipment with smaller screen housings. - Ease of Maintenance
Screen packs are designed for easy installation and replacement. Modular designs and compatibility with automatic screen-changing systems allow for quick maintenance, reducing downtime and improving operational efficiency. - Material Versatility
Pleated screens are available in stainless steel (304, 316), nickel alloys, and other corrosion-resistant metals. They can be customized for high-temperature or chemically aggressive polymer melts, ensuring durability and consistent performance.

Applications of Pleated Extruder Screen Packs
Pleated Extruder Screen Packs are widely used across multiple industries to enhance melt purity and improve product quality. Key applications include:
- Plastic Film & Sheet Extrusion
In film and sheet production, contaminants such as gels or carbonized particles can create defects. Pleated screens ensure consistent film thickness, clarity, and smooth surface finish. - Pipe & Profile Extrusion
Clean polymer melt ensures uniform pipe and profile dimensions, reduces surface imperfections, and minimizes scrap rates. - Blow Molding & Injection Molding Lines
High-quality melt improves part strength, reduces voids, and enhances surface finish. Pleated screens are particularly effective for technical polymers used in automotive and consumer products. - Engineering Plastics Production
For high-performance polymers such as PEEK, PC, and PA, pleated screens remove fine contaminants, ensuring consistent mechanical and thermal properties. - Medical & Packaging Applications
In applications with strict quality standards, pleated screens provide superior melt filtration, ensuring compliance with regulatory requirements and minimizing defects in critical components.
