Aluminum Electroplating and Surface Finish: Precision Solutions
Tailored to Your Specifications
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 are designed to transform your
raw components into finished products that excel in both
performance and aesthetics. Whether you provide detailed
engineering drawings or specific performance criteria, our team of
experts works closely with you to develop customized electroplating
solutions that align with your exact needs.
The Synergy of Aluminum Electroplating and Surface Finish
Aluminum electroplating is more than just a coating process—it is a
precision engineering technique that enhances the inherent
properties of base materials while achieving superior surface
finishes. For manufacturers across aerospace, automotive,
electronics, and marine sectors, the combination of robust
electroplated aluminum layers and refined surface textures directly
impacts product longevity, functionality, and visual appeal.
Our factory operates on a customer-centric model: you provide the product drawings, specify the desired plating
thickness, surface roughness, corrosion resistance standards, and
any industry-specific requirements, and we engineer a production
process flow to deliver results that exceed your expectations.
Our Aluminum Electroplating Process for Optimal Surface Finish
The journey from raw component to a flawlessly electroplated
product involves several critical stages, each meticulously
controlled to ensure surface finish excellence:
- Component Inspection & Drawing Analysis
Upon receiving your product drawings, our engineering team conducts
a thorough review to understand dimensional tolerances, critical
surfaces, and potential challenges. We cross-reference your
specifications with our technical capabilities to confirm
feasibility.
- Pre-Treatment
Surface preparation is the foundation of a superior finish. We
employ industry-leading cleaning techniques—including ultrasonic
degreasing, acid etching, and deoxidation—to remove contaminants,
oxides, and impurities. This step ensures maximum adhesion between
the base material and the electroplated aluminum layer, preventing
delamination and ensuring uniform surface texture.
- Electroplating Execution
Using state-of-the-art electrolytic baths and computer-controlled
power supplies, we deposit aluminum onto the prepared surface. The
process parameters—current density, plating time, and bath
temperature—are adjusted in real time to meet your specified
thickness (typically 5–50μm) and surface uniformity requirements.
- Post-Plating Surface Finishing
Depending on your application, we offer a range of post-treatment
options to enhance surface properties, such as:
- 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.
- Quality Control & Testing
Every batch undergoes rigorous testing, including thickness
measurement (using X-ray fluorescence), adhesion testing (ASTM
B571), corrosion resistance (salt spray per ASTM B117), and surface
roughness analysis (using profilometers).
Surface Finish Options: Tailored to Your Application
We offer a variety of surface finishes to match your functional and
aesthetic needs. The table below outlines key options, their
characteristics, and typical applications:
Surface Finish Type | Roughness (Ra) | Key Properties | Common Applications |
Matte | 1.6–3.2μm | Low reflectivity, uniform appearance | Industrial machinery, structural parts |
Satin | 0.8–1.6μm | Smooth with subtle luster | Automotive trim, consumer electronics |
Semi-Bright | 0.2–0.8μm | Moderate reflectivity, high corrosion resistance | Aerospace components, marine hardware |
Mirror | <0.05μm | High reflectivity, decorative appeal | Lighting fixtures, optical parts, jewelry |
Hard-Anodized | 0.4–1.6μm | Exceptional wear resistance, hardness (60+ HRC) | Heavy equipment, tooling |
