Israel has established itself as a global powerhouse in specialized plastic processing, advanced agricultural technologies, micro-irrigation systems (such as drip emitters), and ultra-thin barrier packaging films. As Israeli manufacturers in industrial centers like Haifa, Ramat Hovav, Tefen, and Migdal HaEmek scale production of high-value polymers, the operational demand for flawless melt purity has reached an unprecedented peak.
Israeli drip irrigation pioneers require ultra-fine melt filtration (10μm to 30μm absolute) to prevent microscopic nozzle blockages in drip emitters. Polymer leaf disc filters guarantee continuous, gel-free melt distribution across high-speed extrusion lines.
Producing UV-stabilized, multi-layer greenhouse covers and silage films demands total removal of cross-linked gels and carbonized specks. High-surface-area leaf discs deliver long stream life under high differential pressures ($\Delta P$).
With Israel’s stringent green legislation driving the adoption of Post-Consumer Recycled (PCR) resins, robust sintered stainless steel leaf disc filters are vital for trapping foreign contaminants, paper fibers, and non-melting polymers.
As a premier China leaf disc filter manufacturer supplying Israeli plants, our engineering team optimizes every aspect of leaf disc geometry, metallurgical selection, and flow dynamics. Standard off-the-shelf filter mesh often fails in continuous polymer melt filtration due to mesh compaction, screen migration, and rapid pressure buildup. Below is an in-depth technical analysis comparing standard woven wire mesh against our advanced 316L sintered metal fiber felt media.
| Performance Characteristic | Standard Woven Wire Mesh Disc | 316L Sintered Metal Fiber Felt Disc | HG Custom Multi-Layer Sintered Composite Disc |
|---|---|---|---|
| Internal Void Volume (Porosity) | 30% - 40% | 75% - 85% Porosity | Up to 82% Porosity |
| Dirt Holding Capacity (DHC) | Baseline (1x) | 3.2x Higher DHC | 3.8x Maximum DHC |
| Pressure Drop Rate ($\Delta P$) | Rapid exponential increase | Linear, gradual pressure increase | Optimized low shear rate $\Delta P$ curve |
| Gel Deformation Retention | Poor (Gels deform & squeeze through) | Superior depth retention mechanism | 3D labyrinth network traps soft gels |
| Metallurgical Durability | AISI 304 / Standard SS | AISI 316L Stainless Steel | AISI 316L / 904L / Alloy 625 (Inconel) |
| Ultrasonic/TEG Thermal Reusability | 3 - 5 Cleaning Cycles | 12 - 15 Cleaning Cycles | 15 - 20 Full TEG Cleaning Cycles |
Hard Leaf Discs: Constructed with a solid, high-precision machined inner hub and heavy-duty outer drainage screens, welded via TIG or electron-beam processes. Designed for high differential pressure operations (up to 250 bar) in BOPP/BOPET lines and continuous hydraulic screen changers. Hard discs provide absolute mechanical stability, ensuring zero bypass under severe thermal expansion.
Soft Leaf Discs: Utilizing a flexible outer rim and lightweight core, ideal for low-pressure continuous filtration systems where rapid changeovers and lower operational costs are required.
The design of the central hub drainage channels is crucial to avoiding polymer stagnation and thermal degradation. Our leaf discs feature computer-simulated radial drainage grooves that maintain uniform shear rates across the entire surface.
By preventing local dead spots, polymer degradation (black spot formation) is eliminated, allowing Israeli processors of transparent PET, PP, and PE films to maintain optical clarity throughout 60-day continuous extrusion runs.
Procurement directors and plant managers in Israel face unique operational challenges: balancing international freight timelines, ensuring seamless compatibility with European/Asian extruder brands (e.g., Erema, Starlinger, Reifenhäuser, KraussMaffei), and minimizing total operational cost (TCO).
Direct supply from China factory eliminates intermediary markups. Coupled with an extended on-stream life and 15+ cleanability cycles using TEG (Triethylene Glycol) pyrolysis, Israeli plants achieve up to 40% annual savings on filter consumables.
We manufacture leaf discs in all international standard outer diameters (OD: 7", 12", 14", 15", 17.7") and custom inner hub dimensions. Whether your line uses standard sliding plate changers or continuous duplex vessel systems, we guarantee 100% mechanical interchangeability.
For processing corrosive halogenated flame retardants or high-temperature engineering plastics like PEEK, PTFE, and PA66, we offer high-grade Hastelloy C-276 and SS 904L sintered leaf discs resistant to chemical degradation up to 400°C.
Delivering industrial components to Israel requires strict compliance with international manufacturing standards, complete traceability, and reliable maritime/air freight channels.
Every batch of leaf disc filters shipped to Israel undergoes stringent Quality Assurance testing in our ISO 9001:2015 certified laboratory:

As Israeli extrusion operators target higher throughput speeds and 100% PCR resin integration, filtration media must evolve. Our R&D engineering roadmap focuses on three core innovations designed to redefine melt purity standards:
Integrating 3D laser-sintering techniques to manufacture multi-layer metal felts with AI-computed pore gradients. Coarser outer layers trap bulk contaminants, while inner micro-layers catch sub-micron gels—increasing overall dirt holding capacity by 50%.
Developing nano-scale metallic surface treatments that reduce melt friction, lower shear stress, and prevent thermal polymer sticking during extended high-temperature runs.
Designing reinforced, high-pressure resilient hard leaf discs engineered specifically for ultra-fast, backwashing screen changers, minimizing polymer purge loss during continuous cleaning cycles.
Sintered metal fiber felt offers a significantly higher void volume (porosity up to 82%) compared to woven wire mesh (30%-40%). This non-woven 3D matrix yields 3 to 4 times higher dirt holding capacity, resulting in lower pressure drops ($\Delta P$) and substantially longer on-stream operating cycles before cleaning or replacement is needed.
For micro-irrigation tape and drip emitter production in Israel, we generally recommend an absolute filtration rating between 15μm and 25μm using 316L sintered metal felt. This ensures all fine particles capable of clogging micro-emitters are captured while maintaining efficient resin flow rates.
Yes, our leaf discs are engineered to 100% exact dimensional specs for direct interchangeability with major European and international filtration equipment (including KraussMaffei, Erema, Nordson, Kreyenborg, and Maag systems). We can manufacture based on your original OEM part numbers or custom technical drawings.
We recommend a standardized 3-stage cleaning protocol: 1) Thermal pyrolysis or Triethylene Glycol (TEG) bath to dissolve residual polymer resin; 2) Ultrasonic solvent cleaning bath to agitate micro-particles out of the metal matrix; 3) High-pressure reverse fluid flushing followed by bubble-point testing to verify 100% flow restoration.
While AISI 316L is our standard material, we supply heavy-duty corrosion-resistant leaf discs in AISI 904L, Hastelloy C-276, and Inconel 625 for processing polymers containing bromine/chlorine flame retardants or acidic additives.
All export shipments include a comprehensive quality binder containing: EN 10204 3.1 Material Test Reports (MTR), ISO 9001 Factory Certificate of Conformity, Bubble Point Test Reports, Dimensional Inspection Certificates, and Commercial Invoices formatted for smooth customs clearance at Haifa/Ashdod ports.
