Half Etched SUS304 Speaker Cover PVD Black Recessed Logo 0.5mm for Premium Car Audio Systems

Half Etched Stainless Steel Speaker Cover with Recessed Branding

A premium door speaker cover is judged from two distances. From one metre away the customer reads a crisp badge and a stepped edge; from ten centimetres away the holes must be identical and the finish flawless. Half etching lets both requirements be met on one piece of 0.5mm SUS304 without a second component, because the recessed pocket and the through holes are produced in the same chemical cycle.

How Two-Depth Etching Works

The sheet is coated, exposed and developed twice. The first exposure defines the through-hole field; the second defines the decorative zones that are only etched part of the way through. Depth is controlled by dwell time and chemistry, so a 0.15mm recess for a logo background or a 0.25mm step along the border can be produced on the same panel with a repeatable floor. No stamping die is required, which means a low volume trim programme can be run at a sensible cost.

PVD Black Finish for Interior Trim

Automotive interior specification usually asks for a dark, low reflectance surface that does not show fingerprints. Our matte PVD black coating is applied after etching, so the hole walls are coated as well and the part does not flash bright when the light angle changes. PVD adds wear resistance for touch surfaces and holds colour on the etched step, which is where paint tends to thin out. Alternative finishes: gunmetal PVD, brushed clear passivation, gloss lacquer.

Design Options on the Same Part

• Recessed logo plate 0.15mm deep behind a raised border
• Micro-perforated acoustic field combined with a solid decorative band
• Half etched groove that reads as a seam between two speaker zones
• Etched rib pattern for stiffness on large door panels
• Countersunk etched marks for LED backlighting

Quality Control for Trim Parts

Each lot is checked on hole diameter, step depth, pattern position and finish adhesion. Parts are supplied with a first article report, and dimensional data can be provided per drawing characteristic for customers running PPAP style approval. Prototype panels are produced from the same film tool used in serial production, so the sample you approve is the geometry you receive.
