Powder Coating: Durable Color Meets Functional Protection
Powder coating is a high-performance surface finishing technique that applies dry powder to metal or plastic components using electrostatic attraction. Once cured under heat or UV light, it forms a tough, uniform layer that resists corrosion, scratches, and fading—while offering vibrant color and texture options.

Detail Information
⚙️ Anodizing: Durable Beauty Through Electrochemical Precision
🧩 What Is Anodizing?
Anodizing is an electrochemical process that enhances metal surfaces by forming a controlled oxide layer. It improves corrosion resistance, wear durability, and visual appeal—especially for aluminum components.
🔁 Process Workflow
- Surface Preparation – cleaning and degreasing
- Etching & Brightening – optional polishing or texturing
- Anodizing Bath – acid electrolyte immersion
- Electrochemical Reaction – oxide layer formation
- Coloring – dyeing the porous layer (optional)
- Sealing – hot water or nickel acetate treatment
🧪 Common Types of Anodizing
| Type | Description | Oxide Thickness |
|---|---|---|
| Type I (Chromic Acid) | Thin, soft layer for aerospace | ~0.5–2.5 μm |
| Type II (Sulfuric Acid) | Standard decorative finish | ~5–25 μm |
| Type III (Hard Anodizing) | Thick, wear-resistant layer | ~25–150 μm |
