Dashang is one of the reliable extruder screens suppliers in China, providing extrusion screens, extruder filter screen products and customized extruder screen pack solutions for plastic, rubber, polymer, recycling and compounding extrusion lines.. Our full product range includes single-layer disc screens, spot-welded multi-layer filter packs, aluminum bound frame filters, and custom special-shaped screens, most of which adopt reliable welding forming technology.
As an integrated factory, we maintain abundant spot inventory of extruder screens in diverse sizes, mesh counts and materials for immediate delivery with competitive factory-direct pricing. Meanwhile, we support fully customized production strictly according to your technical drawings and dimensional requirements, guaranteeing precise fitting and stable long-term extrusion performance for both bulk wholesale distributors and plastic extrusion processing factories.
PRODUCT DESCRIPTION
An extruder screen is a woven wire mesh filtration system welded or folded into specific shapes (round, oval, rectangular, etc.). It is placed before the breaker plate in a plastic or rubber extruder to remove contaminants (dirt, carbonized particles, undispersed pigments) from molten polymers.
How it works:
Melt flow passes through the screen → impurities are trapped → clean melt enters the die → final product has fewer defects and consistent quality.
Key parameters you need to match:
Mesh size (20–150 mesh typical for plastics)
Number of layers (single-layer vs. multi-layer)
Material (stainless steel 304/316L, carbon steel)
Shape & outer diameter (1” to 16” or from 10mm to 500mm)
Wrong specification risk: Too fine a mesh can cause excessive pressure and damage your extruder. Too coarse a mesh lets impurities pass, ruining your final product. Dashang helps you select the optimal spec based on your material, throughput, and equipment model.
Core Advantages of Wire Mesh Extruder Screens vs Other Filter Media
High temperature & high pressure resistance: withstand harsh working conditions inside extrusion barrels steadily;
Reusable after professional cleaning: lower long-term consumable procurement cost;
Stable filtration consistency: effectively intercept gels, carbides, metal shavings and undispersed pigments;Improve finished plastic uniformity: reduce surface spots, bumps and dimensional deviation caused by impurities.
Product Range – Detailed Specifications
Type | Structure | Best For | Mesh Range | Edge Type | Typical OD |
Single-Layer Disc Screen | One woven mesh layer | Low impurity, non-abrasive melts (PVC pipe, profile) | 20–150 mesh | None (raw cut) Seamless aluminum frame | 1″ – 16″ |
Multi-Layer Spot-Welded Filter | 2–8 layers welded together | Medium to high impurity (recycled plastic, rubber) | 20/40/60/100/150 mesh combinations | Spot-welded | 1″ – 16″ |
Aluminum-Bound Frame Filter | Multi-layer mesh + soft aluminum frame | High-pressure, particle scouring (engineering plastics) | Custom up to 500 mesh or Dutch woven mesh | Seamless aluminum frame | Custom |
Oval / Rectangular Special Shape | Single or multi-layer | Larger filtration area, longer cycle | 20–150 mesh | Welded or framed | Custom |

Single-Layer – Low cost, easy replacement Application: Virgin PVC pipe, profile extrusion, low impurity. Pros: Cheap, readily available Cons: Clogs fast, small filtration area
| Multi-Layer (Spot-Welded) – Balanced performance Composed of a support mesh (coarse mesh) and a filter mesh (fine mesh) to intercept impurities in stages; Uniform spot welding on the edges prevents multiple layers of mesh from shifting or layering under the impact of the melt, ensuring stable filtration accuracy and avoiding contamination of the product by mesh shedding. | Aluminum-Bound – High-pressure & edge protection Application: Engineering plastics (PA, PC, POM), high melt pressure Advantage: The soft aluminum frame creates a perfect seal against the breaker plate – no melt bypass.

Customized shaped filter mesh Layer stainless steel wire mesh, which is connected to a specific shape (crescent/arc) through spot welding (spot welding), is combined to filter impurities in the molten plastic in the extruder, and ensure the purity and uniformity of the extruded film, fiber, pipe, plastic particles and other products. | Customized shaped filter mesh Compatible with some models of continuous screen changers or melt filters to filter out impurities in high-temperature and high-pressure plastic melt. The edge wrapping process ensures that the mesh does not deform or delaminate under high pressure, and the elliptical/waist shaped design is designed to match the specific flow channels or slots of the screen changer. | Customized shaped filter mesh Mainly used in plastic granulation, blown film, spinning, sheet extrusion, color masterbatch production and other processes; |

As experienced extruder screens suppliers, Dashang supports customized production according to drawings, samples or technical requirements. We can customize outer diameter, mesh count, wire diameter, number of layers, material grade, edge type, welding method and special shape.
Available options include:
Single-layer extruder filter screen
Multi-layer spot-welded extruder screen pack
Rim-bound screen pack
Aluminum-bound extrusion screen
Round, oval and rectangular screen packs
Special-shaped filter screens for screen changers
Stainless steel 304, 304L, 316 and 316L mesh options
Carbon steel screen options for cost-sensitive applications
For buyers who are not sure which specification to choose, Dashang can recommend a suitable extruder filter screen based on material type, extrusion pressure, production output, impurity level, screen changer model and replacement cycle.
Choosing the right extruder screen pack is important for balancing filtration accuracy, melt pressure and production efficiency.
If the mesh is too coarse, contaminants may pass through and cause black spots, surface defects or die blockage. If the mesh is too fine, the melt pressure may rise too quickly, increasing equipment load and shortening the screen replacement cycle.
For clean virgin plastic, a single-layer extruder filter screen may be enough. For recycled plastic, rubber or masterbatch production, multi-layer extrusion screens are usually recommended because they provide better support, longer service life and more stable filtration. For high-pressure materials or engineering plastics, rim-bound or aluminum-bound screen packs can improve sealing and reduce deformation under pressure.
Dashang extrusion screens are widely used in plastic extrusion and polymer processing industries.
Common applications include:
PVC pipe and profile extrusion
PE, PP and PET sheet extrusion
Plastic film blowing lines
Plastic recycling and granulation lines
Rubber strip and profile extrusion
Masterbatch and compounding production
Engineering plastic extrusion
Chemical and polymer melt filtration
By using a suitable extruder screen pack, manufacturers can improve melt cleanliness, reduce production defects, protect downstream equipment and extend die service life.
