Extruder Screens & Packs

Dashang Wire Mesh is a professional Chinese manufacturer specializing in custom extruder screens with woven wire mesh as filter medium. 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.     

Extruder ScreensHow 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.

Extruder Screens


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.

Extruder Screens 

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;

Technical Specifications & Quality Standards

Wire material standard: ASTM A580 (stainless steel 304, 304L, 316, 316L)                                       

Weave & inspection: ISO9044, ASTM E2016

Surface condition: Flat, clean, no creases, no rust spots, no mechanical damage

Welding: spot welding – consistent fusion without sharp burrs

Frame (if any): Dead-soft aluminum or 304 stainless steel edge wrapping
