Xinhaisen Launches High-Precision Etched Filter Mesh Series – Redefining Filtration with Chemical Etching Technology
2026/04/16
Shenzhen Xinhaisen Technology Limited, a leading precision metal etching manufacturer, today announced the release of its new Fine Mesh Series of high‑performance etched filter screens. Designed for demanding applications in medical devices, aerospace, automotive fuel systems, water treatment, and food processing, the new filter meshes leverage advanced chemical etching technology to deliver levels of accuracy and consistency that traditional stamping cannot match.

With over a decade of experience in etching thin and ultra‑thin metals, Xinhaisen produces filter meshes from stainless steel, copper, and other alloys in thicknesses ranging from 0.02 mm to 1.5 mm. The new series features micro‑holes as small as 0.03 mm, line widths down to 0.015 mm, and a uniformity tolerance of ±0.01 mm – specifications that make it possible to filter particles at micron levels while maintaining mechanical integrity and flow performance.
Why Chemical Etching for Filter Meshes?
Chemical etching (also known as photochemical machining or PCM) is a subtractive manufacturing process that uses photo‑resist and chemical solutions to precisely dissolve unwanted material. Unlike stamping, which shears or punches metal, etching leaves no burrs, no heat‑affected zone, and no mechanical stress on the workpiece. This is particularly critical for fine filter meshes: even microscopic burrs can block pores, trap contaminants, or reduce effective filtration area. Etched filters are flat, clean, and ready to use without secondary deburring operations.
Etching vs. Stamping
| Feature | Chemical Etching | Stamping |
| Minimum aperture size | 0.03 mm | Typically >0.2 mm (limited by punch/die strength) |
| Minimum line / bar width | 0.015 mm | 0.10 – 0.15 mm (risk of punch breakage) |
| Edge quality | Burr‑free, smooth, no rollover | Burrs and die roll often present; requires secondary deburring |
| Mechanical stress | Zero – no tool‑metal contact | High – causes residual stress, warping, and micro‑cracks |
| Tooling / mold cost | No fixed tooling – low cost | Expensive hardened dies, long lead time |
| Prototype & small batch cost | Very low, no die cost, fast setup | High –Die allocation makes small lots uneconomical |
| Design complexity | Unlimited – any shape, holes, slots, free‑form patterns | Limited – complex internal features require progressive dies |
| Material thickness range | 0.02 – 1.5 mm (ideal for thin foils) | 0.1 – 6 mm (thin foils prone to tearing/sticking) |
| Dimensional tolerance | ±0.01 mm (consistent across batch) | ±0.03 mm (consistent across batch) |
| Lead time for new design | 5–7 days (photo‑tool generation) | 4–8 weeks (die design & fabrication) |
| Volume flexibility | Prototype to millions – same process, no penalty | Only economical at very high volumes (>50k‑100k pcs) |
For filter manufacturers and OEMs, the choice is clear: etching delivers higher precision, faster turnaround, and lower entry cost – especially for complex, micro‑scale filtration patterns.
Xinhaisen’s Etching Capability – Built for Critical Filtration
Xinhaisen’s new Fine Mesh Series already serves customers in:
