Explore our primary direct-from-factory catalog of metal filter discs, polymer leaf filters, and heavy-duty pelletizing mesh solutions designed for low pressure drop and ultra-long operational lifespans.
Understanding the fluid dynamics, metallurgical integrity, and structural resistance required for continuous high-temperature, high-pressure polymer extrusion processes.
Multi-layer sintered woven mesh and non-woven metallic fiber felts provide high porosity (up to 85%), exceptionally low initial pressure drop, and superior gel retention efficiency. Manufactured using vacuum diffusion bonding under extreme thermal cycles.
Engineered for high-volume BOPP/BOPET film extrusion lines. Leaf discs feature radial or hub-directed drainage channels to guarantee uniform melt flow distribution, eliminating stagnant zones and preventing thermal polymer degradation.
Pleated and cylindrical stainless steel candle elements optimized for continuous hydraulic screen changers. Built to withstand differential pressure ($\Delta P$) up to 250 bar (25 MPa) without structural buckling or micro-channel collapse.
The shift towards integrated Chinese manufacturing hubs offers wholesale buyers unmatched technical scalability, competitive Total Cost of Ownership (TCO), and advanced material integrity.
By leveraging localized supply chains in Zhejiang and specialized metallurgical facilities, enterprise buyers reduce consumable costs by 35% to 50% compared to European or North American suppliers, without sacrificing ISO-grade performance or stainless steel purity (AISI 304, 316L, 904L, Alloy 600).
Modern automated laser welding, high-precision automated rim wrapping, and ultrasonic cleaning lines allow us to engineer custom disc dimensions, hub connections, and mesh pack layer stacks in as little as 5 to 7 working days, ensuring zero downtime for client plant upgrades.

How continuous screen changers, sub-micron filtration media, and green circular economy mandates are shaping the wholesale filtration industry.
Post-consumer resin (PCR) and post-industrial resin (PIR) processing demand higher dirt-holding capacity. Advanced multi-layer gradient mesh packs capture high contaminant volumes without causing frequent hydraulic pressure spikes.
Modern metal filter discs and candle elements are engineered for multiple pyrolytic and ultrasonic cleaning cycles. Reusable metal media reduce solid hazardous waste disposal fees while maintaining 98%+ original airflow porosity.
Leading wholesale suppliers are integrating computerized bubble point test benches and automated optical inspection (AOI) to eliminate structural wire migration, poor rim crimping, and micro-pinhole flaws prior to global dispatch.
Tailored filtration configurations engineered to meet the unique challenges of specific industrial manufacturing environments.
In twin-screw compounding extruders, our continuous screen mesh packs filter residual inorganic filler agglomerates, metal specks, and degraded gels. This guarantees uniform pellet sizing, pristine color consistency, and prevents downstream die-lip build-up.
High-speed orientation film production requires absolute purity to avoid film breaks. Sintered leaf disc filters eliminate sub-micron gels and gel-like degradation products, ensuring flawless optical transparency and uniform mechanical stretch ratio.
Melt-spun hygiene and medical nonwovens require candle filter elements that deliver low shear stress on the polymer melt while preventing spinneret hole blockage, guaranteeing constant fiber denier and continuous operational runtime.
In polyester (PET) and polyamide (PA6/PA66) yarn production, high-area pleated candle cartridges effectively remove micro-gel fractions, extending spin-pack operational life and lowering thread break frequencies.
Explore our specialized nonwoven, fine wire mesh, and custom-engineered filter elements crafted to meet stringent international quality certifications.
Providing complete material traceability, international compliance certification, and dedicated technical service hubs for seamless cross-border procurement.
All stainless steel wire mesh alloys, sintered felts, and aluminum/copper rim seals comply strictly with EU RoHS, REACH directives, and FDA food-contact standards for pharmaceutical and food-grade plastic packaging extrusion.
To eliminate shipping deformation or corrosion during ocean transit, filter discs and candle elements are double-wrapped in anti-static VCI vapor barrier bags and packed inside custom reinforced wooden export crates.
Our dedicated technical engineers offer 24/7 remote video consulting, pore size analysis, chemical cleaning protocol guidance, and sample testing services to support plant engineers in optimizing filtration parameters.
Expert answers to common engineering, procurement, and customization queries regarding polymer melt filter discs and elements.
Woven wire mesh features a regular geometric grid pattern ideal for surface filtration and larger particle retention. Sintered metal fiber felt consists of 3D non-woven metallic micro-fibers diffusion-bonded under high temperature, offering higher dirt-holding capacity, lower differential pressure, and superior micro-gel separation.
SS304 is cost-effective and suitable for standard non-corrosive polymers like PP and PE. SS316L contains molybdenum, providing superior resistance to intergranular corrosion, high organic acid environments, and aggressive additives commonly found in PET, PA66, or recycled PCR polymer processing.
Please provide outer diameter (OD), inner diameter (ID) if applicable, required filtration rating in microns (μm), polymer type, operating temperature, maximum working pressure ($\Delta P$), rim wrapping material (aluminum, copper, stainless steel), and estimated order quantity.
Yes. Metal filter elements can undergo multiple cleaning cycles using TEG (Triethylene Glycol) solvation, vacuum pyrolysis, calcination, or ultrasonic bath cleaning, restoring up to 95-98% of their initial flow permeability and significantly reducing operational expense.
Every production batch undergoes strict Quality Assurance including Bubble Point Testing according to ISO 4003, air permeability testing according to ISO 4022, visual microscope dimensional verification, and spectral alloy material grade verification (XRF).
Standard OEM samples are produced within 5–7 business days. Full wholesale production orders typically ship within 15–20 days depending on mesh layer complexity, rim wrapping specifications, and order volume.
