Engineered to handle extreme differential pressure ($\Delta P$) and high melt temperatures up to 350°C in demanding production lines.
Slovakia has established itself as the undisputed automotive manufacturing powerhouse of Europe, producing more vehicles per capita than any other country globally. With major OEM hubs operated by Volkswagen in Bratislava, Kia in Žilina, Stellantis in Trnava, Jaguar Land Rover in Nitra, and the newly developing Volvo EV facility near Košice, the surrounding tier-1 and tier-2 plastic compounding ecosystems require uncompromised filtration stability.
Furthermore, under the European Union’s stringent Circular Economy Action Plan and Green Deal directives, Slovak plastic processing facilities are aggressively adopting Post-Consumer Recycled (PCR) and Post-Industrial Recycled (PIR) polymer feeds. Processing recycled Polyethylene Terephthalate (rPET), Polypropylene (PP), and High-Density Polyethylene (HDPE) introduces high levels of particulate contaminants, gels, and aluminum specs into the melt stream, driving an unprecedented surge in demand for robust stainless steel screen mesh filters and high-dirt-capacity candle filter cartridges.
Automotive Plastics: >1.1 Million vehicles assembled annually requiring pristine injection-molded & extruded components.
Recycling Targets: EU Mandate requires 30% recycled content in PET bottles by 2030, necessitating micro-filtration down to 5-10μm.
Logistics Hubs: Seamless multimodal connection via the Danube River port in Bratislava and D1/D2 motorway networks.
How Pujiang HG Plastic Machinery Co., Ltd. solves high-viscosity degradation, shear stress, and filter medium fatigue.
By diffusion-bonding multiple layers of stainless steel (SUS 316L / 304) wire cloth under vacuum at high temperatures, our sintered mesh structure eliminates wire migration, retains fixed pore geometry, and withstands extreme differential pressure ($\Delta P > 210$ bar).
Computer-modeled channel geometries inside our candle filter cartridges reduce residence time distribution (RTD). This prevents polymer degradation, black spots, and carbonization during continuous extrusion of sensitive resins like PET, PA66, and PEEK.
Engineered for maximum economic longevity, our filter elements are designed to undergo repeated TEG (Triethylene Glycol) cleaning, vacuum pyrolysis, and ultrasonic bath treatments, restoring up to 98% of clean pressure differential performance.
Targeted technical configurations optimized for local manufacturing challenges.
Automotive interior trims, under-the-hood structural polyamides (PA6/PA66 with glass fiber filling), and bumper PP compounds require fine filtration without clogging from fiber fillers. Our custom Dutch weave wire mesh packs withstand high shear while removing undispersed agglomerates.
High-speed flexible packaging lines demand zero gel defects to prevent film breakage during biaxial stretching. Our leaf disc filter systems utilize 316L sintered metal fiber felt media, delivering exceptional dirt holding capacity at 3μm to 10μm absolute ratings.
Recycling operators handling post-consumer flakes encounter heavy paper, foil, and silicone contamination. Our continuous screen changer mesh belts (auto-rollback wire cloth) allow uninterrupted operation without shutting down extruders during screen changes.
Meltblown and spunbond polypropylene filtration elements prevent spinneret nozzle blockages. Our candle filter cartridges provide ultra-low pressure drops and extended on-stream lifetime, minimizing costly line shutdowns.
Operating from our modern facility in Zhejiang, China, Pujiang HG Plastic Machinery Co., Ltd. combines advanced German heavy weaving looms, fully automated laser welding robotics, and high-vacuum sintering furnaces to manufacture world-class industrial filter media.
By leveraging integrated raw material sourcing and scale economies, we deliver European-grade precision at 30% to 40% direct cost optimization for Slovak plant managers and purchasing heads.
We ensure smooth, hassle-free customs clearance and logistics direct to Slovak industrial parks via optimized transport routes:
Direct delivery via Vienna International Airport (VIE) or Bratislava Airport (BTS) within 5–7 business days.
FCL/LCL shipments routed through Koper/Hamburg ports connected directly to Dunajská Streda inland terminal.
Meeting all relevant EU directives and technical specifications for industrial production.
All stainless steel alloys (AISI 304, 316, 316L, 904L) undergo strict XRF spectral analysis. Our finished filter elements are fully compliant with EU Regulation EC 1907/2006 (REACH) and Directive 2011/65/EU (RoHS).
Every shipment delivered to Slovakia includes detailed Material Test Certificates (EN 10204 3.1), micron filtration rating verification reports, and bubble point test protocols for complete batch traceability.
Our bilingual engineering team works directly with Slovak plant engineers and procurement teams, offering CAD drawing verification, sample evaluation, and 24/7 online technical assistance.

Addressing procurement, delivery, compatibility, and quality assurance questions.
We provide comprehensive export documentation, including Commercial Invoices, Packing Lists, Certificates of Origin (Form A/EUR.1 if applicable), and EN 10204 3.1 Material Test Reports. Freight can be arranged via DDP (Delivered Duty Paid) or DAP (Delivered at Place) directly to your plant address in Slovakia via our trusted freight logistics partners.
Yes, absolutely. Over 70% of our production consists of OEM/ODM custom orders. You can send us your technical engineering drawings, CAD files, or physical reference samples. We manufacture custom filter disc diameters, pleated candle lengths, and flange connections to exact micrometer tolerances.
Lifespan depends heavily on the polymer cleanliness, filtration velocity, and contamination loading. However, our 316L pleated candle cartridges are designed to undergo between 10 to 20 cleaning cycles (via TEG, calcination furnace, or ultrasonic bath) before requiring replacement, significantly reducing operational consumables expense.
We accommodate both prototyping needs and large-scale industrial supply contracts. For standard wire mesh screens, MOQ starts at 100 pieces. For custom candle filter elements or leaf discs, sample orders of 2 to 5 pieces are welcomed. Standard sample lead time is 5 to 7 working days.
