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.
