Manufactured in Pingxiang with batch-level automated slurry impregnating kilns. Certified for export to Finnish foundries in Tampere, Pori, and Vaasa.
Finland's manufacturing industry is globally celebrated for engineering excellence, marine engine fabrication, high-tolerance forestry machinery, and sustainable metallurgy. Sourcing ceramic foam filtration solutions requires strict adherence to international metallurgical purity, mechanical stress tolerances, and rigorous environmental standards.
Foundries operating throughout northern Europe face challenging logistics and demanding thermal cycles. Zhongtai filters utilize precise mullite-corundum and stabilized zirconia backbones that prevent spalling and washouts during high-temperature pourings up to 1760°C.
Marine propulsion assemblies and mining equipment produced in Finland cannot tolerate non-metallic inclusions. Our 3D open-cell reticulated foam traps sub-micron impurities via deep-bed filtration, reducing rework and ultrasonic scrap rates by up to 64%.
Full verification of all raw material compounds ensures compliance with EU chemical directives, including REACH, RoHS, and emissions audits supporting the EU Carbon Border Adjustment Mechanism (CBAM) required by Finnish port entries.
Compare material bases, pore densities (PPI), and thermal envelopes to match your foundry casting process line requirements.
| Filter Material Type | Pore Density (PPI) | Main Composition | Operating Limit | Primary Industrial Use in Finland |
|---|---|---|---|---|
| Alumina (Al₂O₃) | 10 – 40 PPI | Al₂O₃ ≥ 85%, SiO₂ ≤ 12% | 1200 °C | Continuous aluminum casting, billet extrusion, foil rolling |
| Silicon Carbide (SiC) | 10 – 30 PPI | SiC ≥ 50%, Al₂O₃-SiO₂ bonding | 1500 °C | Ductile & grey iron, heavy machinery, automotive hubs |
| Zirconia (ZrO₂) | 10 – 20 PPI | ZrO₂ (Y₂O₃ stabilized) ≥ 92% | 1760 °C | Stainless steel, marine components, heavy alloy turbines |
| Honeycomb Cordierite | 100 – 400 Cells/in² | 2MgO-2Al₂O₃-5SiO₂ | 1350 °C | RTO VOC thermal abatement systems & air purification |
