Introduction
In high-end fashion, premium bags, outdoor gear, and even home furnishings, a zipper is more than a utility—it’s a statement of quality. Brass separating zippers have become the go-to for designers and manufacturers seeking strength, vintage appeal, and a touch of luxury.
So what makes a truly reliable brass zipper? Here’s an in-depth look at why our brass separating zippers stand out—from raw material selection to precision craftsmanship and quality control.
1. Premium Raw Materials: High-Purity, Eco-Friendly Brass
We use H65 premium brass (65% copper, 35% zinc) to achieve optimal strength, elasticity, and corrosion resistance, along with a naturally rich metallic shine.
- 🌱 Eco-Compliant: Lead-free, RoHS & REACH certified.
- 🔬 Material Screening: Spectral analysis ensures purity and avoids defects from recycled or impure alloys.
Why it matters: Impure brass easily tarnishes or breaks under tension—damaging your brand image.
2. Precision Engineering: Perfect Teeth, Seamless Separation
Our zippers are formed using CNC high-precision stamping machines with a margin of error within ±0.02mm. This ensures smooth and secure engagement every time.
- 🔩 Tooth Uniformity: Each brass tooth is evenly spaced and angle-calibrated.
- 🧷 Separation Unit Quality: Bottom stops, inserts, and boxes are forged and polished for easy snap-in and no jamming.
Surface Finishing:
- Burr removal via vibration polishing
- Dual-step micro-polishing for silky smoothness
- High-pressure air cleansing removes residue and metal dust
3. Multi-Layer Electroplating: Durable + Designer Finish
Each zipper undergoes a triple electroplating process for enhanced aesthetics and durability:
| Layer | Function |
|---|---|
| Nickel Base | Boosts adhesion and oxidation resistance |
| Copper Middle | Adds thickness and wear resistance |
| Final Finish | Custom colors: shiny gold, antique brass, gunmetal, etc. |
🧪 Salt Spray Resistance: 72+ hours with no visible rust or peeling.
4. Total Quality Control: Tested, Trusted, Certified
We follow a 3-stage inspection protocol—pre-production, in-line, and final QC.
- 🔁 Pull Cycle Test: 10,000+ open-close cycles with zero jamming
- 📏 Tooth Alignment: Maintained within ±0.02mm
