3. Full Case Study
3.1 Project Background & Challenge
The client, a European professional audio equipment brand, required a high-precision connector plate for speaker back panels. The plate integrates multiple mounting holes and connector interfaces, demanding strict dimensional accuracy and durability.
Three key challenges were identified:
1. High-density hole precision
Multiple holes with strict spacing (70mm symmetrical layout) required exact alignment.
2. Premium surface & branding
Matte black metal finish with high-contrast, wear-resistant markings.
3. Industrial durability
Scratch-resistant, corrosion-resistant, and long-lasting under heavy usage.
3.2 Engineering Solution
Phase 1: Material Optimization
We selected 5052/6061 aluminum alloy for its lightweight, machinability, and anodizing compatibility.
Phase 2: CNC Precision Machining
Using CNC drilling and laser cutting, all holes and contours were processed with ±0.15mm tolerance.
Phase 3: Surface Finishing
Sandblasting + anodizing created a matte black, anti-scratch, anti-fingerprint finish.
Phase 4: Enamel Printing
High-adhesion enamel ink was applied and thermally cured for durability.
3.3 Results & Performance
· Sample completed in 3 days
· Mass production finished in 20 days
· Precision tolerance: ±0.15mm
3.4 Client Feedback
“The connector plates exceeded our expectations in precision and finish. All connectors fit perfectly, and the printed details remain sharp after repeated use.”
4. FAQ
