Metal Etching Service for Custom SUS304 SUS316 Automotive Speaker Grilles

We provide custom metal etching services for automotive speaker grilles made from SUS304 and SUS316 stainless steel. Our chemical etching process is suitable for car door speaker grilles, dashboard speaker meshes, center console audio covers, headrest speakers, and aftermarket car audio applications. Custom designs based on drawings or samples are welcome, from prototype to mass production.

We use photo-chemical etching to produce precise holes and patterns on stainless steel sheets. The process includes film exposure, development, and chemical etching. It creates no mechanical stress, no burrs, and no deformation, making it ideal for thin stainless steel speaker grilles with fine holes and complex patterns.

We offer both full etching and half etching:

• Full Etching – holes are etched through the material for sound transmission

• Half Etching – partial depth etching for recessed logos, steps, and decorative details

SUS304 is suitable for general automotive interior speaker grilles with good corrosion resistance and cost efficiency. SUS316 offers better resistance to moisture, salt, and chemicals, making it ideal for premium vehicles and harsh environments.

• Material: SUS304, SUS316, and other stainless steel grades

• Thickness: 0.05mm–2.0mm

• Tolerance: up to ±0.02mm

• Minimum hole size: about 0.1mm depending on thickness

• Size: customized according to your drawings

• Additional processes: bending, laser cutting, stamping, welding, assembly

• Surface protection: PE film, paper interleaving, custom packaging

• Production: prototype, small batch, and mass production

Chemical etching does not require hard tooling, so hole shapes are flexible and tooling cost is saved. We can produce round holes, square holes, hexagonal holes, oval holes, slot holes, diamond holes, triangle holes, irregular shapes, logo-shaped holes, gradient patterns, and mixed hole patterns. Hole size, pitch, open area, and layout can be customized based on acoustic and appearance requirements.

• Gloss – smooth and reflective, for premium decorative effects

• Matt – low reflection and fingerprint resistant, for modern interiors

• Brushed – metallic texture with scratch resistance

• Anodizing – color options and improved corrosion protection

• Powder Coating – durable colored finish for specific designs

• PVD / Electroplating – premium metallic colors with wear resistance

• Passivation – improves corrosion resistance after etching
