Extruder Screens & Polymer Filters
Extruder Screens & Polymer Filters for Melt Filtration in Plastic & Rubber Processing
Extruder screens—also known as extrusion filter screens or melt filter screens—are precision woven wire mesh discs, packs, or screens installed inside an extruder to filter contaminants from molten plastic, rubber, and other polymer-based materials.
They play a critical role in ensuring melt purity, stabilizing extrusion pressure, and protecting key components such as the screw, breaker plate, and die.
In modern extrusion lines, extruder screens are considered indispensable filtration components, enabling manufacturers to achieve high-quality film, sheet, pipe, profile, and pellet products.
PFM SCREEN has over 20 years experience in manufacturing extruder screens and screen packs for the polymer and fiber industries. We offer standard and custom products, designed to meet the demanding requirements of the industry.
Extruder Screens & Polymer Filter Product Options
Beyond maintaining an extensive inventory of extruder screens in various sizes, shapes, mesh configurations, and materials for fast delivery, we also manufacture fully customized screens in-house. Our precision production capabilities ensure every screen meets your exact specifications for reliable fit, stability, and long-term performance.
Our extruder screens are engineered to suit a wide variety of screen changers and belt-type filtration systems.
PFM SCREEN’s product range includes:
Continuous Filter Belts
Continuous filter belts provide uninterrupted melt filtration for high-output extrusion lines, delivering stable pressure, extended running time, and exceptional processing efficiency.
Welded Extruder Screen Packs
Welded screen packs combine multiple mesh layers spot-welded in sequence to ensure progressive filtration, high dirt-holding capacity, and consistent melt quality in demanding processes.
Frame Extruder Screen Packs
Frame extruder screen packs feature mesh securely fitted into a rigid aluminum frame, ensuring easy installation, perfect alignment, and superior stability under extrusion pressure.
Pleated Extruder Screen Packs
Pleated extruder screens increase the effective filtration area while minimizing pressure drop, offering longer service life and improved efficiency for fine-filtration extrusion applications.
Cylindrical Extruder Screens
PFM SCREEN specializes in manufacturing a full range of cylindrical filtration elements for extrusion applications. With numerous mesh configurations available, we provide solutions that deliver more uniform flow and reduced pressure drop.
Special Shapes Extruder Screen
