The manufacturing processes for stainless steel hardware accessories (e.g., zippers, buckles, handles) in luggage and bags include:
1. **Stamping**
– High-precision molds shape metal sheets into components.
2. **Casting**
– Molten stainless steel is poured into molds for complex designs (e.g., decorative clasps).
3. **CNC Machining**
– Computer-controlled cutting ensures accuracy for hinges and locks.
4. **Polishing**
– Mechanical or manual polishing creates smooth, scratch-resistant surfaces.
5. **Electroplating**
– Adds coatings (e.g., nickel, PVD gold) for corrosion resistance and aesthetics.
6. **Laser Engraving**
– Custom logos or patterns are etched onto surfaces.
7. **Assembly**
– Components are riveted, welded, or screwed into finished products.
**Key Technologies**:
– Precision tooling for consistency in mass production.
– Salt-spray testing to ensure rust resistance.
– Eco-friendly electroplating to meet international standards (e.g., REACH).
