Custom Etching Processing for Protective Nets and Baffles with Various Aperture Sizes.

We can manufacture ventilation meshes with the following capabilities: Square hole (etched or perforated): minimum size: 0.10 mm Round hole: depending on material and thickness, we can achieve sub-0.10 mm features (<0.10 mm in certain thin materials and optimized processes) Typical open area ratio: 20%-70% Higher or lower open area ratios are available depending on airflow, strength, and structural requirements.

We offer a wide range of materials depending on application requirements, including: Stainless steel (SUS304, SUS316) Aluminum alloys Brass and copper alloys Galvanized steel (for cost-sensitive applications) Material selection can be optimized based on strength, corrosion resistance, and cost targets.

Our standard thickness range is 0.05 mm to 2.0 mm, depending on material and application. For most appliance ventilation covers, the typical range is 0.1 mm to 1.0 mm.

We provide multiple surface treatment options, including: Deburring (standard for all parts) Polishing (matte or mirror finish) Black electrocoating (Black e-coating for corrosion resistance) Black spray coating / painting Passivation for stainless steel Anti-fingerprint coatings (for visible panels)

Yes. Chemical etching naturally produces burr-free edges, so ventilation meshes made by etching are inherently smooth and clean. For parts produced by other processes (such as laser cutting or stamping), we apply additional deburring and surface finishing to ensure: No sharp edges Safe handling Clean appearance No interference with airflow or assembly.
