Engineered to withstand extreme differential pressures and thermal stresses in modern polymer processing lines across Hamburg and Northern Germany.
The Metropolitan Region of Hamburg stands as one of Northern Europe’s most critical industrial hubs, combining world-class maritime logistics through the Port of Hamburg with advanced chemical processing clusters located across Harburg, Veddel, and nearby industrial zones such as Stade and Brunsbüttel. As Europe transitions toward strict circular economy mandates under the EU Green Deal and the German Kreislaufwirtschaftsgesetz (KrWG), polymer processing facilities in Hamburg face dual pressures: maintaining uncompromising melt purity for technical films and aviation-grade polymers while integrating higher ratios of Post-Consumer Recycled (PCR) and Post-Industrial Recycled (PIR) resins.
Within continuous melt filtration systems, the Leaf Disc Filter has emerged as the definitive benchmark for high-viscosity, high-pressure polymer extrusion. Processing thermoplastic resins such as Polyethylene Terephthalate (PET), Polypropylene (PP), Polyamide (PA), and Polycarbonate (PC) demands filtration media that can operate seamlessly at temperatures up to 350°C and differential pressures reaching 320 bar. In film extrusion lines—specifically BOPP, BOPET, and BOPA packaging applications prevalent in Northern Germany—even a single gel particle or micron-scale contaminant can trigger web breaks, leading to catastrophic downtime and substantial material financial loss.
Hamburg’s film extruders operate at ultra-high line speeds (up to 500 m/min). Our leaf disc geometries maintain uniform polymer residence time distribution (RTD), preventing stagnation pockets and thermal degradation of delicate additives.
With Hamburg’s aggressive plastic recycling targets, extruders processing PCR flakes encounter fluctuating particulate loads. Sintered metal fiber felt media captures soft gels and hard specks without rapid pore blinding.
All filter elements exported to German enterprises adhere strictly to DIN EN ISO 9001 quality frameworks, EN 10204 3.1 material traceability, and REACH/RoHS environmental directives.
To support Hamburg’s diverse industrial landscape—from aviation structural plastic component suppliers near Finkenwerder to maritime flexible packaging manufacturers—our factory provides direct OEM engineering solutions that combine high-yield Chinese precision metallurgy with local European operational standards.
A technical evaluation of Leaf Disc Filter performance requires an understanding of media structure, hub construction, hydraulic flow distribution, and differential pressure threshold mechanics.
The core filtration layer determines both dirt-holding capacity (DHC) and pressure drop ($\Delta P$). We manufacture leaf discs using two primary media types:
Leakage between individual leaf discs mounted on a central collector shaft is a primary failure mode in melt filtration. We engineer three distinct hub configurations:
Procuring replacement filter media from European original equipment manufacturers (OEMs) often entails inflated pricing premiums, long lead times (12–16 weeks), and rigid standard dimensions. As a direct China manufacturer with over 20 years of dedicated R&D in metal melt filtration, we deliver a compelling value proposition to industrial buyers across Northern Germany.
By eliminating intermediary trading channels and optimizing vertical production—from wire drawing and sintering to CNC hub machining—we significantly reduce total procurement expenditure without sacrificing metallurgical integrity.
We supply exact dimensional replacements for all major melt filter housing systems, including Kreyenborg, Gneuss, Maag, Nordson BKG, Patt, and Kobelco, ensuring seamless retrofit installation.
Leveraging direct sea shipping lanes from Ningbo/Shanghai directly into the Port of Hamburg (25–28 days) or express air freight to Hamburg Airport (HAM) for critical plant emergencies (3–5 days).
Every batch of Leaf Disc Filters undergo mandatory ISO 4003 Bubble Point Testing to verify absolute pore size ratings, ISO 3968 Flow Resistance evaluations, and 100% helium leak tests on welded hub seams prior to international dispatch.
Location Focus: Hamburg Harbor Industrial Zone & Harburg Logistics Parks.
Technical Challenge: High-speed film stretchers experience frequent line snapping caused by metallic inclusions or un-melted gel particles larger than 5 microns.
Macro Solution: Implementation of 12-inch and 14-inch Leaf Disc Filters configured with 316L sintered stainless steel fiber felt rated at 5 µm absolute. The large active surface area (up to 0.25 m² per disc) minimizes flow velocities, maintaining continuous operation up to 60 days before filter changeout.
Location Focus: Chemical & Circular Economy Parks in Stade and Brunsbüttel.
Technical Challenge: Processing washed post-consumer bottle flakes introduces abrasive paper fibers, aluminum speck remnants, and cross-contaminated polymers, causing rapid pressure spikes.
Macro Solution: Deployment of multi-layer sintered wire mesh leaf discs with heavy-duty outer protective screens (20 mesh / 40 mesh) backing a 40 µm primary filtration mesh. Reinforced hard hubs withstand repeated hydraulic backwashing cycles, reducing single-use consumable cost.
