Materials

Shell Body
High-impact ABS or PC/ABS engineering plastic — lightweight, durable, and dimensionally stable

Surface Finish
Advanced PVD (Physical Vapor Deposition) coating:

  • Rose gold metallic finish
    Options: rose gold, champagne gold, silver, gunmetal, black, or custom PVD colors
    Excellent adhesion, hardness, and corrosion resistance

Key Advantages

  • Premium PVD Metallic Finish — Vacuum deposition process creates a thin, highly uniform rose gold coating with excellent color depth, reflectivity, and long-term stability.

  • Superior Durability — PVD coating provides high hardness, strong adhesion, and excellent resistance to scratches, fingerprints, and daily wear.

  • Clean Modern Aesthetic — Smooth rose gold surface delivers a luxurious, high-end look ideal for wireless earbuds and wearable electronics.

  • Full OEM Customization — PVD color, gloss level, and surface effect can be fully tailored for brand differentiation.

  • Consistent High-Quality Finish — Controlled vacuum process ensures uniform coating thickness and defect-free surfaces across complex curved geometries.

Key Features

  • Rose gold PVD-coated earbud shell

  • Smooth, reflective metallic surface

  • Compact rounded form with precise ear tip interface

  • Lightweight yet rigid ABS construction

  • Fully customizable PVD color options

  • Suitable for wireless earbuds and consumer electronics

  • Low-MOQ sampling supported through flexible production lines

Manufacturing Process (Focus: PVD Coating)

Injection Molding — Precision tooling produces the earbud shell with consistent wall thickness, accurate contours, and smooth surfaces ready for coating.

Surface Preparation — Parts are thoroughly cleaned, deburred, and pre-treated to ensure optimal adhesion for the PVD layer.

PVD Coating — Applied in a vacuum deposition chamber. Multi-stage process includes:

  • Surface activation and cleaning under vacuum

  • Deposition of thin metallic layers (typically titanium or zirconium based) to create the rose gold color

  • Precise control of coating thickness for uniform color, hardness, and adhesion

  • Optional protective top layer for enhanced durability and fingerprint resistance

Quality Inspection — Visual and instrumental checks for color consistency, coating thickness, adhesion strength, hardness, and surface defects.

Final Assembly & Packaging — Shells prepared for internal component assembly, final visual inspection performed, and parts packed according to customer specifications (bulk or private-label ready).

All PVD color options and coating formulations are available for OEM customization. Lead times and MOQs can be adjusted for sampling through mass production.
