Precision-fabricated filter cartridges engineered for extreme differential pressures, thermal stability, and maximum contamination retention in polymer extrusion.
The Greater Istanbul economic corridor—spanning key Organized Industrial Zones (OSB) such as Gebze OSB, Tuzla Chemical & Leather Industrial Zone, Hadımköy, and nearby Çerkezköy—represents one of Europe’s most dynamic manufacturing landscapes for plastics processing, technical textiles, and packaging films. As Turkish plastic converters and chemical fiber producers aggressively upgrade their production capabilities to meet stringent European Union Green Deal standards, demand for zero-defect polymer melt filtration has scaled exponentially.
Sourcing high-reliability Screen Mesh Filters and Candle Filter Cartridges is no longer merely an operational line-item; it is a fundamental strategic requirement. High-viscosity polymers (PET, PA6, PA66, PP, PE) operating under continuous hydraulic pressures reaching up to 250 bar and temperatures exceeding 300°C demand filtration media engineered with zero tolerance for structural degradation or pore bypass.
Understanding how multi-layer screen meshes and pleated candle cartridges manage fluid shear stress, gel deformation, and contaminant capture during high-temperature extrusion.
Polymer melt pleated candle cartridges utilize longitudinal pleating of sintered stainless steel fiber web to increase effective filtration surface area by 300% to 500% compared to standard cylindrical elements. This massive surface enlargement directly reduces face velocity across the filter medium, minimizing polymer shear stress ($\dot{\gamma}$), decreasing pressure drop accumulation ($\Delta P/dt$), and preventing gel shearing/breakthrough.
Extruder screen mesh filters deployed in Istanbul’s film and recycling lines incorporate engineered multi-layer layups: a coarse drainage mesh on the upstream side, a micro-fine Dutch Twill weave (e.g., 24/110, 50/250, 165/1400) in the middle for absolute particle retention, and a robust supportive backing mesh. This structure eliminates screen deformation under extreme melt pressures while ensuring smooth polymer flow profiles.
Unlike standard woven wire mesh which acts strictly as a surface filter, sintered metal fiber web (non-woven 3D stainless steel matrix) provides deep depth filtration. With porosity rates exceeding 75-80%, it offers significantly higher dirt-holding capacity ($g/m^2$) for organic gels, carbonized degradation particles, and inorganic contaminants, ensuring uninterrupted extrusion cycles.
From medical nonwoven production in Tekirdağ/Çorlu to high-speed BOPP packaging lines in Gebze, our filtration systems deliver tailored performance for regional industrial applications.
Producers of polypropylene (PP) spunbond and meltblown fabrics for medical hygiene and filtration media require ultra-clean polymer melts to prevent spinneret hole blockage (filament breaks). Polymer candle filter elements rated at 15μm to 25μm absolute with zero fiber migration ensure continuous 24/7 spinning without line stoppage.
Biaxially oriented polypropylene (BOPP) and polyester (BOPET) film extrusion lines operating at speeds over 500 m/min require massive continuous polymer filtration units (CPF). Custom pleated candle filter assemblies remove micro-gels that cause film pinholes or optical hazing, guaranteeing high tensile strength and barrier clarity.
With Turkey’s aggressive push toward circular plastics and export compliance for recycled content, recyclers processing post-consumer bottle flakes face high contamination levels. Continuous auto-backwash screen mesh filters and robust multi-layer rimmed screen packs filter out aluminum traces, paper fibers, and cross-linked polymers efficiently.
Polyamide (Nylon) and Polyester continuous yarn spinning mills require high-temperature vacuum-sintered stainless steel filter candle elements. These elements withstand high melt temperatures up to 340°C while maintaining low pressure drops to avoid thermal degradation of sensitive polymers.

The decision depends on your contamination profile, polymer viscosity, and filtration mode. Sintered metal fiber web (a 3D non-woven matrix of stainless steel micro-fibers) offers deep depth filtration, exceptionally high porosity (up to 80%), and superior dirt-holding capacity. It is ideal for high-purity applications like Spunbond nonwovens, BOPP films, and fine fiber spinning where soft gels must be captured without rapid pressure spikes. Conversely, woven wire mesh provides precise surface filtration, predictable pore openings, and rigid structural stability, making it preferred for high-viscosity recycled polymers or continuous backwash screen changers where surface cake removal is critical.
We provide streamlined export logistics to all major Turkish ports, including Ambarlı (Istanbul European Side), Haydarpaşa, and Yılport / Dilovası (Kocaeli industrial belt). Standard sea freight transit times from Ningbo/Shanghai port to Ambarlı range between 22 to 28 days. For urgent production shutdown situations, we offer expedited air freight to Istanbul Airport (IST) or Sabiha Gökçen Airport (SAW) with typical customs clearance transit of 3 to 5 business days. All shipments include full ATR / EUR.1 origin documentation, ISO 9001 mill test certificates (EN 10204 3.1), and customized HS Code classification (e.g., 8421.99) for smooth Turkish customs entry.
Our standard stainless steel 316L pleated candle filter cartridges are engineered for an operational differential pressure ($\Delta P$) of up to 120 to 150 bar, with reinforced inner core designs capable of surviving collapse pressures up to 210 bar (3,045 PSI). This structural robustness prevents element deformation during sudden viscosity shifts, cold-start extruder procedures, or high-pressure surge conditions common in heavy-duty polymer recycling.
Yes. We specialize in precision reverse engineering and custom OEM fabrication. By providing physical samples or technical dimensional drawings, our engineering department produces exact drop-in replacement candle filter cartridges, leaf discs, and screen packs matching your original vessel's mechanical tolerances, sealing surface geometry (e.g., NPT, metric threaded, chevron gasket, or flat metal seal), and thermal expansion coefficients.
When cleaned according to professional protocols (combining TEG hydrolysis, vacuum pyrolysis, and ultrasonic bath treatments), a high-quality Pujiang HG stainless steel sintered candle filter cartridge typically achieves between 15 to 20 full cleaning cycles before performance degradation occurs. Bubble point testing (ISO 4003) and clean pressure drop measurement ($\Delta P_0$) should be conducted after each cycle to ensure pore structure integrity.
