OEM/ODM Chemical Etched Micro-Perforated Metal Speaker Grilles for Automotive Acoustics
Product Overview
Xinhaisen’s precision-etched car speaker grilles are high-performance acoustic mesh parts designed to protect vehicle speakers while delivering superior sound clarity. Manufactured using advanced photochemical etching technology, these grilles offer intricate patterns, burr-free edges, and consistent open areas. Ideal for automotive audio systems, they combine durability with sleek aesthetics, ensuring long-lasting performance in demanding vehicle environments.
Manufacturing Process
-
Photochemical Etching (PCE) – A mask is applied to the metal sheet, and chemical etchant removes unwanted areas to create precise patterns.
-
No mechanical stress, no burrs, no heat-affected zones.
-
Suitable for prototype to high-volume production with low tooling costs.
Product Features
-
High Acoustic Transparency – Custom open-area ratio for optimal sound transmission.
-
Burr-Free & Flat – No secondary finishing required; safe to handle and install.
-
Intricate Patterns – Any hole shape (round, slot, hexagon) down to 0.03mm diameter.
-
Material Flexibility – Stainless steel, aluminum, copper, and other alloys.
-
Corrosion Resistant – Compatible with automotive environmental standards.
-
Cost-Effective – Low tooling cost, fast design changes.

FAQ
- Q1: Can you make custom hole patterns for car speaker grilles?
Yes. Any 2D pattern (circles, hexagons, slots, logos) can be etched without new tooling costs. - Q2: What is the thinnest grille you can produce?
We can etch down to 0.02mm thickness, ideal for lightweight acoustic applications. - Q3: Will etching affect the metal’s strength or flatness?
No. Photochemical etching is a stress-free process. Parts remain flat and strong. - Q4: Do you provide finishing services?
Yes. We offer deburring, cleaning, passivation, and surface coating as needed. - Q5: What is your typical lead time for car speaker grilles?
Sample tooling: 5–7 days. Mass production: 7–15 days depending on quantity. - Q6: Can you produce large quantities for OEM automotive suppliers?
Absolutely. We handle both small batches and million-piece orders with consistent quality.
