TL;DR — Nylon is the highest-output and cheapest entry point. Metal is slower and pricier but commands premium prices on jeans and jackets. Plastic suits outerwear and luggage where colour and weight matter. The teeth-forming machines are not interchangeable; downstream stages can be shared.
The three zipper families at a glance
| Family | Tooth material | Forming method | Typical end products |
|---|---|---|---|
| Nylon (coil) | Nylon monofilament | Coiling onto tape | Garments, bags, general OEM |
| Metal | Brass, aluminium, copper wire | Stamping wire onto tape | Jeans, jackets, premium goods |
| Plastic (Vislon) | POM resin | Injection moulding onto tape | Outerwear, sportswear, luggage |
The differentiator is the chain-forming step: how the teeth are attached to the tape. Everything that follows — gapping, slider mounting, top/bottom stop, cutting, testing — is broadly similar across the three.
Output and speed
Production speed is the single biggest gap between the three families.
| Family | Typical chain-forming speed | Why |
|---|---|---|
| Nylon | 80 – 120 m/min on high-end | Continuous coiling — no per-tooth operation |
| Metal | 30 – 60 m/min | Each tooth is stamped from wire individually |
| Plastic | 30 – 50 m/min | Each tooth is moulded onto tape |
For a factory shipping high-volume garment OEM, nylon is the throughput champion. For lower-volume premium work, output matters less than per-meter margin — which favours metal and plastic.
Entry cost — what a single line costs
Real numbers depend on your output target and automation level, but a useful rough order:
- Nylon zipper machine line — lowest CapEx. Coiling head + gapping + slider + cutting is the simplest assembly.
- Metal zipper machine line — wire stamping + die maintenance push tooling costs up.
- Plastic zipper machine line — injection moulding adds the highest equipment complexity, but the machinery has a long life.
If you are entering the zipper business for the first time, start with nylon. Add metal or plastic when the order book justifies a second line.
Application match — buy for the orders you have
The clearest rule in zipper machinery: buy for the products you actually sell. A wrong-family machine sits idle.
| Your customers make… | Buy |
|---|---|
| Casual garments, T-shirts with hoodies, basic bags | Nylon line |
| Jeans, leather jackets, premium fashion | Metal line |
| Ski wear, sportswear, hard-shell luggage | Plastic line |
| Waterproof outerwear, dry bags, marine | Plastic or nylon line + waterproof coating |
| Pure decorative / fashion-statement zippers | Metal — colour and weight matter |
Shared downstream equipment
The chain-forming machine must match the zipper type. Downstream, most machines can be shared across families with minor change-over:
- Gapping machines
- Slider mounting (pin & box, open-end)
- Top / bottom stop machines
- Cutting machines
- Testing equipment (pull, torque, load)
This is how multi-product zipper factories scale: add a second chain-forming line, but keep one gapping / slider / cutting / testing pool.

Request a Free QuoteFrequently asked questions
- Which zipper machine has the highest output?
- Nylon coil lines run fastest — high-end machines reach 80–120 meters per minute on chain forming. Plastic and metal lines are slower because each tooth is moulded or stamped individually.
- Which zipper machine has the lowest entry cost?
- A nylon zipper line is usually the cheapest entry — the coiling head is less complex than metal stamping or plastic injection moulding.
- Can one machine make nylon, metal and plastic zippers?
- No. The teeth-forming step is fundamentally different. Downstream stages can be shared, but the chain-forming machine must match the zipper type.
- What if I want to sell all three zipper types?
- Build separate chain-forming lines for each type, then share downstream equipment where possible. Most multi-product factories start with one family and add lines as orders grow.
