Special Shapes Extruder Screens
Special Shapes Extruder Screens | Custom Mesh Filters for Polymer & Rubber Extrusion
Special Shapes Extruder Screens are custom-engineered filtration elements designed to meet the specific needs of polymer, rubber, food, chemical, adhesive, and masterbatch extrusion lines. Unlike conventional round or rectangular screens, special-shape screens are manufactured according to customer-provided drawings, CAD files, or application requirements.
These screens are made from high-quality stainless steel, nickel alloys, brass, phosphor bronze, or other specialty metals depending on the processing temperature, chemical resistance, and mechanical strength required.
Advantages of Special Shapes Extruder Screens
1. Tailored to Your Extrusion Equipment
Precisely manufactured according to your dies, breaker plates, or screen changing system, ensuring perfect fitting and reliable operation.
2. Improved Filtration Efficiency
Custom geometry optimizes melt distribution, reduces dead zones, and enhances particle capture for stable product quality.
3. Enhanced Durability
Made from corrosion-resistant and heat-resistant alloys up to 600–1200°C, depending on material selection.
4. Wide Range of Mesh & Layer Options
Single-layer, multi-layer, spot-welded, rim-bound, or framed structures available to ensure long lifespan and stable pressure performance.
5. Compatible with Automatic and Manual Screen Changers
Kidney-shaped and special-cut screens are widely used in continuous rotary screen changer systems for non-stop production.
