Explore our primary line of high-durability stainless steel mesh components, candle filter elements, and polymer leaf discs optimized for plastic extrusion and fiber spinning.
An in-depth metallurgical and mechanical evaluation of stainless steel wire cloth manufacturing, structural weave dynamics, and viscoelastic polymer melt filtration performance.
In modern high-viscosity polymer processing, continuous plastic recycling, and synthetic fiber extrusion, the selection of stainless steel mesh media is governed by severe thermomechanical stress, differential pressure ($\Delta P$), and reactive chemical media. As a primary China Stainless Steel Wire Mesh Supplier & Exporters, Pujiang HG Plastic Machinery Co., Ltd. utilizes strict quality control protocols across raw wire drawing, annealing, and precise shuttleless weaving.
The operational longevity of wire mesh filters depends heavily on alloy composition. Standard commercial grades such as AISI 304 provide adequate tensile strength and basic oxidation resistance up to 300°C. However, for severe environments involving organic acids, corrosive additive packages, or high-purity polymer melt spinning (e.g., PET, PA66, PBT), marine-grade AISI 316 and 316L (low-carbon variant) are mandatory. The presence of Molybdenum (2.0% - 3.0%) in SUS 316L dramatically enhances resistance to localized pitting and crevice corrosion, ensuring zero metallic contamination in the downstream polymer stream.
Technical Insight: Austenitic stainless steel wire (SUS 316L) subjected to vacuum hydrogen bright annealing exhibits superior grain structure ductility, enabling wire mesh elements to withstand extreme pressure differentials up to 250 bar during continuous polymer screen changer operations without micro-fissuring or wire displacement.
The retention efficiency ($\beta$-ratio) and dirt-holding capacity ($DHC$) of woven stainless steel wire mesh are fundamentally determined by the geometric structural arrangement of warp and shute (weft) wires. Our manufacturing facilities operate automated computer-controlled weaving looms capable of producing custom geometric patterns tailored to client fluid dynamics:
| Stainless Steel Grade | Weave Type | Mesh Count (per Inch) | Wire Diameter (mm) | Absolute Retention (μm) | Primary Application Area |
|---|---|---|---|---|---|
| SUS 304 | Plain Weave | 20 x 20 – 150 x 150 | 0.12 – 0.40 | 100 – 500 | Standard Plastic Extrusion & Recycled Pelletizing |
| SUS 316 / 316L | Twill Weave | 100 x 100 – 400 x 400 | 0.03 – 0.10 | 35 – 100 | BOPP / BOPET Film Lines & Fine Chemical Straining |
| SUS 316L | Dutch Twill Weave | 165 x 1400 – 325 x 2300 | 0.025 – 0.071 | 5 – 25 | High-Viscosity Polymer Candle Filters & Melt Spinning |
| SUS 316L / 904L | 5-Layer Sintered Mesh | Custom Composite | Multi-Layer Wire | 1 – 20 (Absolute) | Ultra-High Pressure Polymer Melt Leaf Discs |
Capitalizing on mature industrial clusters, vertical supply chain integration, and rigorous quality assurance protocols to deliver world-class filtration media.
By controlling every manufacturing stage—from initial wire drawing and annealing to loom weaving, ultrasonic cleaning, and laser cutting—we eliminate middleman markups and secure complete batch traceability.
Every export lot undergoes rigorous quality testing including PMI spectrographic chemical verification, bubble point pore size determination (ISO 4003), and high-pressure burst resistance testing before dispatch.
We partner directly with OEM equipment builders and plant maintenance leads to design bespoke filter geometries, non-standard outer diameters, specialized rim borders (aluminum, copper, stainless steel), and custom pleat counts.

Custom continuous extruder wire mesh screen packs designed for heavy contaminant loading (paper, aluminum foil, wood specks) in post-consumer ABS, PE, PP, and PET pelletizing lines.
High-precision pleated polymer candle filter cartridges engineered with SUS 316L fiber felt media, guaranteeing ultra-low pressure drop ($\Delta P$) and long continuous spinning runs.
Heavy-duty wire cloth strainers and high-pressure filter cylinders designed for chemical catalyst recovery, oil refining fluid purification, and high-temperature gas filtration.
A strategic framework for international buyers to streamline procurement, mitigate supply risks, and lower Total Cost of Ownership (TCO).
When sourcing industrial wire mesh from China, international procurement teams must align technical parameters beyond standard mesh count. Evaluating wire diameter tolerance, open area ratio (%), and weight per square meter ensures reliable flow dynamics and structural rigidity under pressure.
For high-viscosity applications like polymer melt filtration, choosing between woven wire mesh and sintered metal fiber felt is crucial:
Export Compliance & Packaging Protocol: All Pujiang HG filter products destined for European, American, and Southeast Asian markets are ultrasonically degreased, sealed in moisture-proof VCI anti-corrosion barrier bags, and packed in reinforced export-grade plywood crates to ensure pristine condition upon arrival.
Direct technical and procurement responses from our engineering specialists.
SUS 304 is a versatile 18/8 chromium-nickel stainless steel providing excellent strength and standard corrosion resistance. SUS 316L contains 2-3% Molybdenum and lower carbon content, offering significantly enhanced resistance to chloride pitting, acidic additives, and chemical degradation at high melt temperatures (above 280°C).
Mesh count refers to the number of openings per linear inch. Micron rating represents the actual distance between adjacent wires. The formula is: Aperture Size (microns) = (25,400 / Mesh Count) - Wire Diameter (microns). Our technical team provides precise conversion charts for all custom weave configurations.
Yes. High-quality stainless steel candle filters and leaf discs engineered by Pujiang HG can undergo multiple cleaning cycles using TEG (Triethylene Glycol) pyrolysis, calcination ovens, ultrasonic baths, and chemical solvent flushes, restoring up to 95% of original permeability.
Our facility operates strictly under ISO 9001:2015 Quality Management Standards. We supply complete material test reports (MTR), mill certificate compliance according to EN 10204 3.1, and bubble point test documentation with every commercial shipment.
