Precision Melt Filtration from the Wire Mesh Capital of China
ANPING RUIBEI METAL MESH FACTORY, trading worldwide as BM Metal Mesh, has confirmed the latest production round of its stainless steel Dutch woven extruder filter screens. Operating from Anping County since 2015, the factory has built a dedicated filtration division that now covers more than 200 standard extruder screen references, supplied to plastic recyclers, compounders and masterbatch producers across Europe, the Middle East and the Americas.
More than 80 percent of the factory's output is exported today, and extruder screens have become one of the fastest-growing lines in the portfolio. The reason is simple: every kilogram of recycled polymer passes through a screen pack, and the quality of that screen decides both output rate and final pellet purity.
What the Extruder Filter Screen Range Covers
The range is built around Dutch woven and twilled Dutch woven structures, where warp and weft wires of different diameters create a dense, high-precision filter surface with a smooth upstream face and an open downstream face. This architecture traps contaminants on the surface instead of burying them inside the weave, which extends service life and keeps pressure build-up predictable.
| Parameter | Standard Offering |

| Material | AISI 304, AISI 316L stainless steel; galvanised and mild steel options |
| Weave type | Plain Dutch weave, twilled Dutch weave, reverse Dutch weave |
| Mesh count | 24 x 110, 14 x 88, 12 x 64 and other standard combinations |
| Filtration rating | 5, 10, 20, 25 micron and custom ratings |
| Disc diameter | Φ175 mm, Φ200 mm, Φ220 mm, up to 500 mm on request |
| Wire diameter | 0.25 mm / 0.35 mm and custom warp-weft pairings |
Key Performance Features
- High flow through open area — square aperture geometry keeps melt pressure low and stabilises throughput on high-speed recycling lines.
- Contaminant holding capacity — the Dutch weave depth stores grit, paper fibre and unmelted particles without sudden screen blinding.
- Accurate micron rating — each batch is verified so that a 20 micron screen behaves like a 20 micron screen, shift after shift.
- Clean edge finishing — discs are punched and deburred to protect breaker plates and avoid leakage at the seal line.
- Repeatable supply — identical specifications can be re-ordered months later, which matters for plants running fixed process recipes.
Typical Applications
These screens are used in single and twin screw extruders, blown film lines, sheet extrusion, pipe extrusion, granulation downstream of washing lines, and in rubber compounding where steel mesh discs protect gear pumps and dies. They are equally suited to laboratory extruders where small diameter filter cloth is required.
Why Buyers Work With BM Metal Mesh
With 50 to 100 employees and annual sales between USD 800,000 and 1.3 million, the factory is large enough to run continuous weaving and punching lines, yet small enough to accept custom diameters, non-standard mesh counts and mixed-material screen packs without long tooling delays. Orders ship from Tianjin and Qingdao ports, and the export team supports documentation, palletisation and consignment planning for distributors who resell under their own brand.
Buyers evaluating a new filtration supplier are invited to request samples of the 24 x 110 and 5 micron screen constructions for line trials. Technical drawings, mesh certificates and packing lists are provided with every quotation.
