Low Price Metal Zipper Plating Coloring Machine
This equipment applies metallic plating and subsequent color dyeing to zipper teeth made from brass, zinc alloy, or stainless steel. The process combines electro‑deposition of a protective metal layer with a controlled dye bath to achieve uniform hue and corrosion resistance. It is designed for continuous operation in garment accessory factories where consistent finish and high throughput are required.
Technical Overview
The machine consists of a pre‑cleaning station, a plating tank with rectifier, a rinsing module, a coloring tank, and a drying/conveying section. Current density is adjustable from 2 to 6 A/dm², allowing plating thickness control between 0.5 µm and 3 µm. Temperature in the coloring tank is maintained between 40 °C and 80 °C depending on the dye chemistry, and conveyor speed ranges from 5 m/min to 30 m/min to match line capacity.
Typical Specifications
| Parameter | Value / Range |
|---|---|
| Plating Metal Options | Nickel, Tin, Copper (custom alloys on request) |
| Plating Thickness | 0.5 µm – 3 µm (adjustable) |
| Coloring Temperature | 40 °C – 80 °C |
| Conveyor Width | 200 mm – 600 mm (customizable) |
| Power Consumption | ≈ 12 kW (depends on load) |
Key Features
- Independent control of plating current and dye temperature for precise thickness and hue.
- Closed‑loop filtration reduces chemical consumption and extends bath life.
- Quick‑change fixtures allow switching between zipper widths in under 15 minutes.
- Low‑voltage rectifier minimizes energy use while maintaining deposition rate.
- Integrated monitoring logs current, temperature, and conveyor speed for traceability.
Applications
Metal zippers used in denim, outerwear, luggage, and sports gear require a finish that resists wear, sweat, and UV exposure while providing a consistent aesthetic. The plating layer adds corrosion protection, and the coloring step delivers brand‑specific shades without secondary painting. By integrating both steps, the machine reduces handling, minimizes batch‑to‑batch variation, and supports just‑in‑time production lines.
Application Examples
| Industry | Typical Zipper Type | Required Plating Thickness |
|---|---|---|
| Denim Apparel | Brass teeth, 3 mm width | 1.0 µm Nickel |
| Outdoor Gear | Zinc‑alloy teeth, 5 mm width | 2.0 µm Tin + UV‑stable dye |
| Luggage | Stainless‑steel teeth, 4 mm width | 0.8 µm Copper |
Customization Options
The machine can be adapted to specific production needs. Conveyor width, tank volume, and rectifier rating are sized according to line speed and part dimensions. Plating chemistry (e.g., nickel‑free, tin‑copper alloys) and dye formulations are selectable based on regulatory requirements and desired colorfastness. Optional add‑ons include inline thickness gauges, spectrophotometric color sensors, and automated load‑unload robots.
Quality Control & Testing
Process verification includes periodic measurement of plating thickness via X‑ray fluorescence, adhesion testing using tape‑pull methods, and colorimetry to confirm ΔE < 2 against standard swatches. Bath analysis monitors metal ion concentration and pH to maintain deposition efficiency. All data are logged for traceability and can be exported for audit purposes.
Shipping & Packaging
Units are secured on a steel skid with vibration‑isolating foam corners, wrapped in polyethylene film, and placed inside a wooden crate treated for moisture resistance. Export shipments include desiccant packs and shock‑indicating labels. Documentation such as electrical schematics, installation manuals, and CE conformity declarations are supplied in both printed and electronic formats.
