Stainless Steel Mesh Filter Baskets

Stainless Steel Mesh Filter Baskets

Anping CREMOTIVE Wire Mesh Products CO., LTD’s Stainless Steel Mesh Filter Baskets are designed for integration into coffee brewers, tea infusers, and industrial liquid processing systems. These baskets—cylindrical or truncated‑cone in shape—feature precision‑woven stainless steel mesh bodies supported by welded rims and perforated end caps to withstand mechanical stress and fluid pressures.

Manufacturing & Materials
Mesh bodies are woven from 316L stainless steel wire in a 100 × 100 wires‑per‑inch plain‑weave pattern, yielding openings of approximately 150 µm. The mesh sleeve is seam‑welded longitudinally, then affixed to a 1.0 mm thick stainless steel top and bottom ring, TIG‑welded to maintain food‑grade integrity. For heavy‑duty or high‑temperature applications, the basket may include an internal support core of perforated stainless tubing to prevent collapse under back‑pressure.

Design Variations

• Cone‑Style Baskets: Commonly 54 mm to 58 mm in base diameter for espresso machines, with 45° side‑wall angles.

• Straight‑Wall Cylinders: Used in drip brewers and industrial flow‑through filters.

• Dual‑Mesh Inserts: A coarse outer mesh (200 µm) paired with a finer inner mesh (80 µm) for depth filtration and extended run times.

Functional Benefits

• Enhanced Flow Uniformity: Even water distribution prevents channeling in coffee extraction or ensures consistent contact time in industrial sieving.

• Robust Construction: Welded joints and reinforced rims resist deformation from repeated insertion and removal, maintaining seal integrity.

• Corrosion Resistance: 316L alloy resists tea‑ and coffee‑acidic pH as well as harsh cleaning chemicals.

Applications

• Espresso Machines: Metal baskets eliminate the need for paper filter pads, reducing waste and improving brew clarity.

• Pour‑Over & French Press: Mesh baskets capture grounds while allowing flavorful oils to remain in the beverage.

• Laboratory & Industrial: Small‑scale process screening where reusable, chemically resistant baskets are preferred.

Quality Assurance & Service Life
Each basket undergoes leak testing at 2 bar and dimensional verification of inner diameter, wall thickness, and mesh aperture. Weld quality is confirmed by visual and dye‑penetrant inspection. With proper cleaning—daily rinsing and weekly ultrasonic cycles—mesh filter baskets remain functional for thousands of use cycles, offering a sustainable alternative to disposable elements.
