More Details
Background & Customer Needs
This project involved an illuminated decorative logo component designed to display a brand mark through backlighting (example shown: “PSI”).
The customer required small-batch prototypes to validate:
- Visual appearance under ambient and dark conditions
- Light uniformity of the backlit logo
- Surface quality of the electroplated finish
- Assembly feasibility of the LED module and wiring
The component needed to deliver a premium metallic look while maintaining precise light transmission through the logo area.
Structural Design & Materials
Electroplated ABS Housing
The main body was produced from ABS plastic, followed by chrome or nickel electroplating.
This structure provides:
- A mirror-like metallic appearance
- Lightweight and easy manufacturability
- Compatibility with complex logo geometries
ABS allows stable injection molding while electroplating achieves a high-end metal surface effect.
Illuminated Logo Area
The logo section was designed using translucent or semi-transparent plastic, allowing light to pass through from the back.
Key elements include:
- Integrated LED backlight module
- Red and black power wires for low-voltage supply
- Controlled light output for clear logo visibility
This design ensures the logo is visible without light leakage into non-illuminated areas.
Light Diffusion Texture Area
The textured region on the right side functions as a decorative light-guiding surface.
Its purpose is to:
- Improve light diffusion
- Reduce hotspots
- Enhance the overall visual depth of illumination
Key Challenges
Illuminated electroplated components present several technical challenges:
- Balancing metal appearance and light transmission
- Preventing plating defects near translucent areas
- Achieving uniform backlighting without light bleed
- Ensuring stable LED module installation and wiring
The customer needed a rapid prototyping solution that closely replicated mass-production quality.
Rapid Prototyping Solution
Injection Molding + Electroplating
The housing was first injection molded with dedicated translucent logo areas.
After molding, selective electroplating was applied to achieve the metallic surface while preserving light-transmitting regions.
LED Backlight Module Assembly
LED components were installed behind the logo area and connected via insulated wiring.
This assembly allowed:
- Functional illumination testing
- Evaluation of brightness and color temperature
- Verification of electrical and structural stability
Key Features & Advantages

Why This Case Matters
This case shows how surface processing is critical for illuminated components.
By validating vacuum film coating and painting at the prototype stage, customers can: Avoid costly color and light issues later | Speed up design approval | Reduce risk before tooling investment
Production Process & Quality Assurance
- DFM Review: Logo geometry, plating boundaries, and lighting layout are reviewed before tooling.
- Rapid Prototyping: Small-batch prototypes are produced for visual and functional validation.
- Light & Appearance Inspection: Components are tested under backlight to ensure uniform illumination and clean surface finish.
- Quality Commitment: If illumination or surface issues are caused by processing defects, rework support is provided.
