Why Choose Hebei CangChen Foundry Filtration Products?

1. Full Product Portfolio

Hebei CangChen supplies a full range of molten metal filtration consumables for foundries, covering fiberglass mesh filters, fiberglass cap filters, silicon carbide ceramic foam filters, alumina ceramic foam filters and related auxiliary products.

Our filters are engineered for aluminum alloy, gray iron, ductile iron, cast steel and copper alloy casting.

Whether you run gravity casting, low-pressure die casting, sand casting or investment casting, we can offer the matched filtration solution. 

We avoid forcing customers to use one single product; we recommend the most suitable filter according to your metal type, pouring temperature, casting weight and quality requirement.

Fiberglass filters (fiberglass mesh & cap filters):

Made of alkali-free E-glass or high-silica fiberglass yarn with special high-temperature coating.

● Low gas emission, no contamination to molten metal; will not change alloy composition

● Excellent thermal shock resistance; no preheating required before pouring

● Flexible, easy to cut on-site; low flow resistance for smooth filling

● Effectively block slag, oxide films and large non-metallic inclusions, reduce turbulence during pouring

● Working temperature range: up to 850℃ for aluminum; high-silica grade can withstand up to 1620℃ for iron & steel casting

Ceramic foam filters (SiC / Alumina / Zirconia):

3D interconnected porous ceramic structure for deep depth filtration.

● Silicon carbide filters: ideal for gray iron, ductile iron, copper alloy, continuous working temp up to 1500℃

● Alumina filters: designed for aluminum alloy, stable under repeated thermal cycles

● High slag holding capacity, capture fine micron-level inclusions

● Improve mechanical properties, surface finish and tightness of high-end castings

● Reduce scrap rate caused by slag and inclusion defects significantly

2. Strict Quality Control & Certification

● All production runs follow ISO 9001 quality management system.

● Every batch undergoes sampling inspection: dimensional check, high-temperature resistance test, gas emission test, strength and slag retention test. We keep full batch test records for traceability.

● Our products are stable batch-to-batch; dramatic performance fluctuation is avoided.

● We can provide certificates, test reports, packing list, commercial invoice and full export documents for customs clearance. Third-party inspection is acceptable for big orders.

3. Strong Customization Capability

We support both standard sizes and fully custom fabrication.

● Fiberglass mesh: custom roll width, sheet size, mesh opening, shapes (round, square, irregular)

● Fiberglass cap filters: custom diameter, height, edge reinforcement for your pouring cup

● Ceramic foam filters: custom dimensions, thickness, hole counts (10ppi,20ppi,30ppi etc.)

● We only need your drawings or samples to develop customized products.

● Small trial orders for custom items are welcome, to help you test before mass production.

4. Production Capacity, Lead Time & Global Shipping

We maintain large daily production capacity for fast delivery.

● Standard items: short lead time, ready stock available for urgent orders

● Custom products: predictable production schedule, we will inform you of progress regularly.

● We are experienced in international export.

● We are familiar with sea freight, air freight, DAP / DDP terms.

● Products are packed in export cartons and reinforced pallets to prevent damage during long ocean transit.

● We can arrange shipment to ports worldwide.

5. Total cost advantage & lower scrap rate

✅Our filters help foundries cut overall production cost rather than just filter procurement cost.

✅Less slag & inclusion defects reduce scrap, rework and rejection losses.

✅The savings on defective castings far exceed the filter cost.

✅ As direct manufacturer, we eliminate middleman markup and offer volume-based tier pricing for long-term partners.

✅We provide equivalent quality at a more competitive price.

6. Professional Technical Support & After-sales

● Our foundry technical team has rich experience in molten metal filtration.

● We do not merely sell filters. We help you select the correct filter type, mesh size / PPI, installation position in gating system.

● We can share installation guidance, casting case studies and troubleshooting advice.

● If you encounter casting defects during trial use, our engineers will analyze the root cause together with you.

● We provide fast response for inquiries. We support long-term after-sales communication for overseas partners.
