Chemical Etched Smoke Detector Mesh Micro-Hole Stainless Steel Insect Screen for Fire Alarm Sensor Protection

Product Overview

Xinhaisen’s precision-etched smoke detector mesh is designed to allow optimal smoke entry while blocking insects, dust, and electromagnetic interference. Manufactured using high-accuracy photochemical etching, our meshes ensure consistent hole size, burr-free edges, and excellent flatness for reliable smoke detector performance.

Etching Process Used

• Material cleaning – Remove oil and contaminants from metal sheets.

• Lamination & exposure – Apply photoresist and transfer the mesh pattern via high-precision film.

• Development – Remove unexposed photoresist to reveal the etching area.

• Spray etching – Use acid etchant to dissolve unprotected metal, forming micro-holes.

• Stripping – Remove remaining photoresist.

• Inspection & packaging – 100% optical inspection before shipment.

Product Features

• Ultra-fine holes – Minimum aperture down to 0.03mm.

• Fine line width – As narrow as 0.015mm.

• High uniformity – Tolerance within ±0.01mm.

• Burr-free & smooth – No mechanical stress or edge deformation.

• Material options – SUS304, SUS316, brass, nickel, etc.

• Thickness range – 0.02mm – 1.5mm.

• Custom shapes – Round, square, hexagonal, or slotted holes.

FAQ

• Q1: What is the smallest hole size you can etch for smoke detector mesh?
  A: We can etch holes as small as 0.03mm in materials 0.02mm–1.5mm thick.
• Q2: Can you produce non-circular hole patterns?
  A: Yes. Square, slot, and custom-shaped holes are available.
• Q3: Is the mesh flat after etching?
  A: Yes. Chemical etching produces no burrs or warping, maintaining excellent flatness.
• Q4: Do you offer sample prototyping?
  A: Absolutely. We provide low-volume prototypes for testing before mass production.
• Q5: What is your typical lead time?
  A: 5–7 working days for prototypes, 7–15 days for mass production.
• Q6: Which certifications do you have?
  A: We comply with ISO9001:2015 quality management standards.
