History
EVAD Anodizing, established in 2024, focuses on Type II anodizing services for small to medium-sized, highly complex 6061 aluminum parts. Our company's specialization addresses a gap in the industry for high-quality anodizing of small-medium sized components, ensuring precision, durability, and aesthetic appeal.
At EVAD Anodizing, we serve a diverse range of industries that require high-quality anodizing of intricate aluminum parts. Some of the key industries we cater to include: Scientific Instrument, Optomechanics, Cryogenics, and Outdoor Equipment.
Process
Key Aspects of Detailed, Delicate Anodizing Services:
1. Surface Preparation:
Pre-Anodizing Cleaning: A thorough cleaning process is essential to remove contaminants (such as oils, greases, and fingerprints) from the aluminum surface. This step ensures a smooth, defect-free finish.
Etching and Polishing: Depending on the desired surface finish, parts may undergo etching or mechanical polishing to smooth out imperfections or create a matte or reflective finish per customer request.
2. Precise Process Control:
Controlled Sulfuric Acid Bath Composition: The quality and consistency of the anodizing bath are closely monitored to ensure that the anodizing layer is applied evenly across complex geometries.
Voltage and Current Adjustments: Adjustments to voltage and current during the anodizing process ensure that the oxide layer is of uniform thickness, critical for parts with delicate or intricate designs.
Time Control: Anodizing time is carefully managed to control the oxide layer thickness, especially when precision thicknesses are required (e.g., micrometer-level accuracy).
3. Custom Finishes and Colors:
Color Consistency: For decorative anodizing, custom dyes can be used after anodization to create vibrant and consistent colors. Careful handling is required to ensure uniform coloration on complex or delicate parts.
Matte, Glossy, or Satin Finishes: Specific finishes are achieved through varying anodizing techniques, and careful attention ensures uniformity in texture and appearance, especially for high-end aesthetic applications.
Clear Anodizing: A delicate, clear anodizing process that preserves the natural metallic appearance of aluminum while still providing the protective oxide layer.
4. Handling Intricate and Small Parts:
Delicate Fixtures and Masking: Specialized fixtures are used to suspend parts in the anodizing bath without causing surface defects. Masking techniques are employed for areas that should not be anodized, especially for components with tight tolerances or sensitive surfaces.
Attention to Detail for Small or Complex Parts: Parts with fine features or complex geometries require extreme care to avoid uneven anodizing, buildup of oxide, or damage during the process.
5. Post-Anodizing Services:
Sealing: After anodizing, parts are sealed, typically in hot water or a chemical solution, to close the pores of the oxide layer. This step is critical for ensuring long-term corrosion resistance and locking in dyes.
Final Inspection: A rigorous inspection process (including visual checks and surface thickness measurements) is undertaken to ensure that the finish meets precise standards.
6. Customization & Collaboration:
Bespoke Solutions: Collaborating closely with clients to meet specific requirements, whether it’s achieving a certain color, finish, or anodizing thickness. This level of customization is key for industries like aerospace, luxury goods, or high-end electronics.
