China Screen Mesh Filter Suppliers & Exporter for Uruguay

For post-consumer resin (PCR) pelletizing (such as washed agricultural film or post-consumer bottles in Uruguay), AISI 304 stainless steel is the industry standard due to its excellent balance of high tensile strength and cost efficiency. However, if processing municipal waste streams containing acidic residue or fire-retardant polymers, we strongly recommend AISI 316 or 316L, which contains Molybdenum for enhanced pitting corrosion resistance.

Extrusion pressure spikes occur when fine filtration layers (e.g., 200 mesh) are unsupported or subjected to uneven contamination loads. A optimized multi-layer pack structure uses a coarse outer cover mesh (e.g., 20 mesh), followed by an intermediate drainage layer (60 mesh), the fine filtration layer (200 mesh), and a heavy backing screen (20 mesh). This gradient structure traps large particles first while maintaining mechanical rigidity under high pressure drops.

Yes, we engineer Reverse Dutch Twill Weave (RDTW) continuous belt filter mesh compatible with major European screen changer brands (including Maag, Nordson/Kreyenborg, BritAS, and EREMA). We customize roll widths (e.g., 60mm to 300mm), roll lengths (standard 10m, 20m, 50m rolls), and high-tensile warp wire spacing to prevent edge fraying during automated indexing.

Sintered stainless steel leaf discs and candle filter elements can be cleaned and reused multiple times. Recommended protocols include: (1) Thermal pyrolysis / TEG (Triethylene Glycol) boiling to burn off residual polymer matrix, (2) Ultrasonic solvent bath cleaning to dislodge inorganic contaminants, and (3) Hydro-jet high-pressure backwashing. We provide detailed maintenance guidelines with every exported order to Uruguay.

Standard production turnaround for custom screen packs or wire mesh rolls is 10 to 15 days. Ocean freight from Ningbo or Shanghai port to Port of Montevideo typically takes 32 to 40 days. For urgent plant maintenance shutdowns in Uruguay, we offer express air freight via DHL, FedEx, or air cargo direct to Carrasco International Airport (MVD) with 5 to 7 days transit time.

All raw stainless steel wires are mill-certified with full heat chemical traceability. Our manufacturing processes utilize non-contaminating degreasing solvents and ultrasonic rinsing, producing clean wire mesh filter elements certified compliant with MERCOSUR GMC Resolution 56/92, FDA 21 CFR 177.1520, and EU 10/2011 regulations for direct contact with foodstuffs.

We supply rimmed screen packs framed in soft Aluminum, Copper, or Stainless Steel. Aluminum rims are widely used for general plastic extrusion because they deform slightly under clamping pressure, providing an air-tight seal against breaker plate housings. Copper rims are preferred for higher melt temperature applications.

Yes, Pujiang HG Plastic Machinery provides free evaluation samples for standardized wire mesh screens, spot-welded packs, and small filter discs. Clients in Uruguay only cover standard courier freight charges. Contact our sales engineering desk to specify your required dimensions and micron ratings.
