Anping Xinye Metal Wire Mesh Products Co., Ltd, based in Hengshui, Hebei, China, is proud to present our SS316 Perforated Chemical Etching Screen designed specifically for precision filter applications. Manufactured using advanced chemical etching technology, this screen offers ultra-fine, burr-free holes with exceptional dimensional accuracy, ensuring consistent filtration performance in demanding environments. The use of premium SS316 stainless steel provides outstanding corrosion resistance, making it ideal for pharmaceutical, food & beverage, chemical, and water treatment industries.
Key Features and Technical Specifications
- Material: High-grade SS316 stainless steel – excellent resistance to acids, alkalis, and chlorides.
- Manufacturing Process: Photo-chemical etching (photolithography) – produces precise, uniform holes without mechanical deformation or burrs.
- Hole Geometry: Available in round, square, slot, and custom shapes; hole size from 0.05mm to 20mm.
- Thickness Range: 0.1mm to 3.0mm, with tight tolerances (±0.01mm for thin sheets).
- Open Area: Customizable from 20% to 80% depending on hole pattern and pitch.
- Surface Finish: Options include electropolishing, passivation, or as-rolled – reduces particle adhesion and improves cleanability.
- Size: Single piece up to 1500mm × 3000mm; can be cut to exact dimensions or supplied in rolls.
- Edge Quality: Smooth, burr-free edges – no secondary finishing required.
Technical Parameters (Typical Values)
| Parameter | Value |
| Material Grade | SS316 (UNS S31600) |
| Thickness Tolerance | ±0.01mm (≤0.5mm), ±0.02mm (>0.5mm) |
| Hole Position Tolerance | ±0.015mm |
| Maximum Sheet Size | 1500mm × 3000mm |
| Minimum Hole Size | 0.05mm (50 microns) |
| Aspect Ratio (Thickness:Hole) | Up to 2:1 (standard), customizable upon request |
| Open Area Tolerance | ±1% |
Advantages and Benefits
- Superior Filtration Precision: Chemical etching allows for extremely fine and consistent hole patterns, ensuring accurate particle size cut-off (down to 50 microns).
- No Burrs or Deformation: Unlike mechanical punching, etching produces clean, stress-free openings – prevents clogging and extends service life.
- Excellent Corrosion Resistance: SS316 material withstands aggressive chemicals, high temperatures, and repeated sterilization cycles (autoclave, CIP).
- Customizable Patterns: We can create any hole shape, arrangement, and taper angle to meet your specific filtration requirements.
- High Mechanical Strength: Despite thin sheets, the material retains structural integrity under pressure differentials up to 5 bar (depending on thickness and open area).
- Easy Cleaning and Maintenance: Smooth surface finish minimizes particle adhesion; can be cleaned by backflushing or ultrasonic methods.
- Cost-Effective for Large Volumes: Etching is a photolithographic process – once the tooling is made, unit cost decreases significantly for high quantities.

Frequently Asked Questions (FAQ)
1. What is the minimum hole size achievable with chemical etching on SS316?
We can produce holes as small as 0.05mm (50 microns) with high consistency. For smaller holes, etching may still be feasible but the thickness-to-hole aspect ratio must be considered.
2. Can you provide screens with custom hole shapes (e.g., hexagonal, slotted)?
Yes, chemical etching can create virtually any 2D shape. Common shapes include round, square, slot, hexagonal, and triangular. We can work from your CAD drawing or sample.
3. What is the maximum sheet size you can produce?
Our standard maximum sheet size is 1500mm × 3000mm. Larger sizes may be possible by joining multiple sheets, but this is not recommended for filtration applications requiring uniform openings.
4. Do you offer surface treatments to improve cleanability?
Yes, we offer electropolishing and passivation. Electropolishing reduces surface roughness and improves chemical resistance. Passivation enhances the natural oxide layer for corrosion protection.
5. How does the cost compare to laser-cut or punched screens?
Chemical etching has a higher initial tooling cost due to photomask creation, but for high volumes or complex patterns, it becomes more economical. For small quantities, laser cutting may be cheaper. We can advise based on your order quantity.
6. Can you supply screens for food-grade applications?
Yes, SS316 is food-grade compliant. We can deliver screens with a clean surface finish suitable for food contact, and we offer optional certificates of material compliance upon request.
7. What is the typical lead time for custom orders?
For standard thicknesses and patterns, lead time is 15–20 working days after tooling approval. Complex patterns or larger thicknesses may require 25–30 working days.
8. Do you provide samples before mass production?
Absolutely. We can produce small sample sheets (e.g., 200mm × 200mm) for your evaluation. Sample cost is usually waived for serious inquiries, with shipping charges borne by the customer.
