Custom Metal Zipper Tooth Making Machine
This machine forms individual zipper teeth from continuous metal strip through precision stamping and bending operations. It enables manufacturers to produce teeth with tight dimensional tolerances required for smooth slider movement.
Technical Specifications
Typical operating parameters are shown below; actual values can be adjusted according to tooth profile and material thickness.
| Parameter | Typical Value | Adjustable Range |
|---|---|---|
| Maximum tooth width | 5.0 mm | 3.0 – 6.0 mm |
| Tooth pitch (center‑to‑center) | 4.2 mm | 3.5 – 5.0 mm |
| Strip thickness capacity | 0.20 – 0.40 mm | 0.15 – 0.50 mm |
| Production speed | 120 strokes/min | 80 – 150 strokes/min |
| Motor power | 2.2 kW | 1.5 – 3.0 kW |
| Machine footprint (L×W×H) | 1800 mm × 900 mm × 1500 mm | Customizable per layout |
Applications
Zipper teeth produced by this equipment are used wherever a reliable metal closure is required. The tooth geometry directly influences slider fatigue life and resistance to corrosion.
- Outerwear and sportswear where abrasion resistance is critical.
- Luggage and travel gear that undergo repeated opening/closing cycles.
- Outdoor equipment such as tents and backpacks exposed to UV and moisture.
- Industrial protective clothing requiring fire‑retardant metal alloys.
Customization Options
The machine accepts interchangeable tooling sets, allowing rapid changeover between different tooth profiles without extensive re‑calibration. This flexibility supports short‑run production of specialty zippers.
- Tooth shapes: standard, concealed, invisible, and reinforced.
- Material compatibility: brass, nickel‑silver, aluminum, stainless steel, and coated alloys.
- Adjustable pitch and width via cam‑type feeding mechanism.
- Optional inline lubrication system for high‑speed runs.
Quality Control Philosophy
Each production batch undergoes dimensional inspection using laser micrometers to verify tooth width and pitch within ±0.02 mm. Surface finish is measured for roughness (Ra < 0.8 µm) to ensure smooth slider travel.
| Inspection Item | Method | Acceptance Criteria |
|---|---|---|
| Tooth width | Laser micrometer | ±0.02 mm of nominal |
| Tooth pitch | Optical encoder | ±0.03 mm cumulative over 100 mm |
| Surface roughness | Contact profilometer | Ra ≤ 0.8 µm |
| Material hardness (where applicable) | Rockwell B scale | 55 – 70 HRB (depends on alloy) |
Frequently Asked Questions
Q: Can the machine be adapted for custom tooth profiles not shown in the catalog?
A: Yes. Tooling can be designed from CAD drawings; lead time for custom dies is typically 3‑4 weeks.
Q: What information is required to obtain a quotation?
A: Desired tooth dimensions, material type, expected annual volume, and any special features such as coating or lubrication.
Q: How are machines shipped internationally?
A: Units are secured in a wooden crate with internal bracing and shock‑absorbent foam; export documentation includes CE marking and a detailed installation manual.
