Chemical Etched Micro Perforated Car Speaker Covers From Prototype to High-Volume Orders

Product Overview

Xinhaisen specializes in high-precision etched metal car speaker grilles. Using advanced photochemical etching, we produce burr-free, uniform mesh patterns for automotive audio systems. Our grilles are used in door speakers, dashboard tweeters, and subwoofer covers. Materials range from stainless steel to copper alloys, with thicknesses from 0.02mm to 1.5mm.

Etching Process Overview

• Material Preparation – Select coils/sheets (SUS304, 430, etc.).

• Cleaning & Lamination – Apply dry film photoresist on both sides.

• Exposure – UV transfer of speaker grille pattern (hex, round, slot).

• Development – Remove unexposed resist to open pattern areas.

• Etching – Spray etchant simultaneously from both sides for precision.

• Strip & Inspect – Remove remaining resist; 100% optical inspection.

Key advantages: No tooling cost, no burrs, no stressed edges.

Product Features

• Burr-free & Flat – No secondary deburring needed.

• High Open Area – Up to 85% for superior acoustic transparency.

• Fine Details – Line width down to 0.015mm; hole diameter from 0.03mm.

• Uniform Tolerance – ±0.01mm even for complex patterns.

• Material Versatility – Stainless steel (304, 316L), copper, brass, nickel, titanium.

• Corrosion Resistant – Suitable for automotive interior/exterior applications.

• Custom Shapes – Round, oval, square, or hex holes.

FAQ

• Q: What hole shape is best for car speaker grilles?
  A: Round or hexagonal holes provide excellent acoustic transparency and mechanical strength. We also customize based on your audio requirements.
• Q: Do you charge a tooling fee?
  A: No. Photo etching uses digital artwork, so there are no hard tooling costs, even for complex patterns.
• Q: Can you etch stainless steel speaker grilles that resist rust?
  A: Yes. We commonly use SUS304 for interiors and SUS316L for humid or outdoor vehicle areas.
• Q: What is the thinnest car speaker grille you can make?
  A: 0.02mm, but for most automotive applications, 0.15mm–0.5mm is recommended for durability.
• Q: How do I send my speaker grille design?
  A: Send DXF, AI, or CAD files. We can also scan and replicate an existing grille.
• Q: Is the etching process environmentally friendly?
  A: Yes. Our process is RoHS-compliant and uses closed-loop etchant regeneration systems.
