At Shanfeng, we specialize in delivering high-quality aluminum electroplating services that meet the unique requirements of diverse industries. With a focus on precision, durability, and surface excellence, our processes transform raw components into finished products that excel in both performance and aesthetics.
The Synergy of Aluminum Electroplating and Surface Finish
Aluminum electroplating is a precision engineering technique that enhances base material properties while achieving superior surface finishes. For manufacturers across aerospace, automotive, electronics, and marine sectors, this combination directly impacts product longevity, functionality, and visual appeal.
Our customer-centric model begins with your product drawings and specifications for plating thickness, surface roughness, corrosion resistance standards, and any industry-specific requirements. We then engineer a production process to deliver results that exceed expectations.
Our Aluminum Electroplating Process for Optimal Surface Finish
1. Component Inspection & Drawing Analysis
Our engineering team conducts a thorough review of your product drawings to understand dimensional tolerances, critical surfaces, and potential challenges, confirming feasibility against our technical capabilities.
2. Pre-Treatment
We employ industry-leading cleaning techniques including ultrasonic degreasing, acid etching, and deoxidation to remove contaminants and ensure maximum adhesion between the base material and electroplated aluminum layer.
3. Electroplating Execution
Using state-of-the-art electrolytic baths and computer-controlled power supplies, we deposit aluminum onto prepared surfaces with real-time parameter adjustments to meet specified thickness (5-50μm) and uniformity requirements.
4. Post-Plating Surface Finishing
We offer multiple post-treatment options:
- Polishing: Achieves mirror-like finishes (Ra < 0.05μm) for decorative or optical applications
- Anodizing: Creates a hard, corrosion-resistant oxide layer (20-100μm) with customizable colors
- Passivation: Improves chemical resistance for marine or industrial environments
- Sealing: Reduces porosity and enhances surface smoothness
5. Quality Control & Testing
Every batch undergoes rigorous testing including thickness measurement (X-ray fluorescence), adhesion testing (ASTM B571), corrosion resistance (salt spray per ASTM B117), and surface roughness analysis.
