Hebei CangChen: Your Reliable One-Stop Manufacturer for Foundry Molten Metal Filtration Solutions

We manufactures fiberglass filters, TF COMBO BAG, alumina / silicon carbide / zirconia ceramic foam filters for aluminum, steel, iron & copper casting. In-house production, custom sizes & flexible MOQ for global foundries.

When molten metal flows into your mold, hidden oxide films, slag and tiny inclusions can ruin castings, raise scrap rates and hurt your profit margin. Choosing the right molten metal filter is one of the most cost-effective upgrades any foundry can make — and picking a trusted manufacturer matters just as much.

Under our registered trademark CANGENDAS®, Hebei CangChen Imp. & Exp. Trade Co., Ltd. is a professional manufacturer and exporter specializing in full-range foundry filtration products.

We own two production plants, one dedicated to fiberglass filtration products and another for ceramic foam filters, serving foundries and metal importers across Southeast Asia, Middle East, Brazil, Europe and North America.

Our Complete Foundry Filter Product Portfolio

We cover all mainstream molten metal filtration requirements, so you can source all your filter items directly from our factory:

1. Fiberglass Filters & TF COMBO BAG

Our high-temperature carbonized fiberglass mesh, cap filters and TF COMBO BAG are engineered for molten aluminium filtration. Widely adopted in aluminum slab, aluminum ingot and aluminum wheel production lines. The woven fiberglass media removes alumina inclusions, stabilizes melt flow and reduces turbulence during pouring. High-silica fiberglass grades are also available for iron and copper alloy applications.

2. Alumina Ceramic Foam Filters

Designed specifically for molten aluminum and aluminum alloys. The 3D open-cell structure delivers deep-bed filtration, capturing fine oxide particles while converting turbulent melt flow into laminar flow. Ideal for aluminum ingots, large aluminum plates and automotive aluminum castings.

3. Silicon Carbide (SiC) Ceramic Foam Filters

Excellent thermal shock resistance for cast iron and copper liquid filtration. Stable under high pouring temperatures, widely used in ductile iron and bronze casting workshops.

4. Zirconia Ceramic Foam Filters

The premium choice for steel casting. Outstanding high-temperature stability against molten steel, perfect for high-grade steel castings requiring strict internal quality standards.

With years of international export experience, we handle packaging, shipping and export paperwork efficiently. We ship to over 20 countries and regions, familiar with the needs of metal foundry markets including Brazil, India, Southeast Asia and the Middle East.

How to Select The Correct Filter For Your Casting?

● Molten aluminium (aluminum ingot, slab, wheel): Fiberglass TF COMBO BAG or Alumina ceramic foam filter

● Cast iron / copper alloy: Silicon carbide ceramic foam filter

● Molten steel: Zirconia ceramic foam filter

If you are unsure which filter fits your casting line, send us your casting parameters. Our technical team will offer a tailored recommendation and free product samples for your on-site test.

All in All

Poor melt filtration creates hidden losses: defective castings, wasted raw materials and extra machining costs. With Hebei CangChen and our brand CANGENDAS® as your filtration manufacturing partner, you get consistent filter performance, responsive technical advice and factory-direct pricing for your foundry.
