What are the main types of zipper making machines?

A zipper line is built from several machine types: a tape weaving loom; a teeth-making machine (nylon coiling, resin injection moulding, or metal teeth forming, depending on the zipper); a gapping machine; a slider/head attaching machine; top- and bottom-stop machines; for open-end zippers a hole-punching and pin & box machine; and a cutting machine, plus dyeing, winding and testing equipment. Each type does one job in the sequence.

What is a zipper attach machine?

In zipper manufacturing, the attaching machine is the head/slider mounting machine — it fits the complete slider onto the zipper chain. A direct in-line feeder handles common slider pulls, while a side-feed machine handles fancy or irregular pulls. (This is different from a garment zipper-attaching sewing machine used by clothing factories to sew a finished zipper onto a garment.)

Do different zipper types need different machines?

Yes — but only partly. How the teeth are made differs by material: nylon teeth are coiled, resin teeth are injection-moulded, and metal teeth are formed from wire, each on its own machine. The finishing machines — gapping, slider attaching, stops, cutting and testing — are broadly shared across all three, which is why factories can add a second zipper material at lower cost.

Types of Zipper Making Machines: Full List & What Each Does

Q: What is a zipper gapping machine?

A zipper gapping machine removes the teeth at set intervals along the continuous chain to create the spaces (gaps) where the slider and stops sit and where each finished zipper begins and ends. There are separate gapping machines for nylon, resin and metal zippers. Accurate gapping fixes the finished length and keeps every later step aligned.

A finished zipper passes through a whole sequence of machines, each doing one job. If you are planning a zipper line or comparing suppliers, this is the complete list of zipper making machine types — what each one does, and which zipper it makes — from Jeso (Primo Zipper Group), a factory with 40+ years building zipper machinery.

The machines fall into three groups: chain making (weave the tape and make the teeth), finishing (turn the chain into finished zippers), and support (dyeing, winding, testing). Here they are in order.

Chain-making machines

Tape weaving machine

A needle loom weaves the polyester zipper tape that the teeth attach to. Tape width and edge are matched to the zipper size (#3, #5, #8, #10…). Consistent tape is the foundation of a smooth zipper. A zipper tape weaving machine is the first machine in any line.

Teeth-making machine (by material)

This is the machine that defines the zipper type — and it is different for each material:

Zipper	Teeth-making machine	How it works
Nylon (coil)	Coiling machine + sewing machine	A coiling machine winds the nylon monofilament into the coil teeth; a separate sewing machine then stitches the coil onto the tape
Resin (plastic)	Injection moulding machine	Injects molten POM into a long-chain mould to form the teeth
Metal	Teeth-forming machine	Forms each tooth from metal wire and clamps it onto the tape

The nylon coiling machine is often called a zipper chain forming machine. For the resin route see our zipper injection molding machine guide; for the full nylon route see the nylon zipper production line.

Finishing machines

Zipper gapping machine

The gapping machine removes teeth at set intervals to create the spaces (gaps) where the slider and stops go, and where each finished zipper begins and ends. There are separate gapping machines for nylon, resin and metal teeth. Gapping accuracy sets the finished length and the alignment of every step after it.

Zipper attach (slider mounting) machine

The attaching machine in a zipper factory is the head/slider mounting machine — it fits the complete slider onto the chain. A direct in-line feeder suits common slider pulls; a side-feed machine handles fancy or irregularly shaped pulls. (Note: this is different from a garment zipper-attaching sewing machine, which clothing factories use to sew a finished zipper onto a garment.)

Stop machines (top & bottom)

Stops keep the slider on the zipper. Different machines apply different stops: aluminium-wire top stops, transparent heat-fused top stops, aluminium-wire bottom stops, H-shaped metal bottom stops, and — for open-end zippers — pin & box machines. The right stop depends on the zipper material and whether it is open-end or closed-end.

Hole-punching machine

Open-end (separating) zippers need locating holes for the pin & box at the base, so a hole-punching machine punches them before the pin & box is fitted.

Cutting machine

The cutting machine cuts the continuous chain into finished zippers at the gapped points. Separate cutters serve open-end and closed-end zippers; ultrasonic cutting adds extra precision and seals the cut edge for higher-spec work.

Support machines

Colour mixing — blends colour into POM resin before moulding so resin teeth come out in the right colour.
Dyeing — a roller dyeing machine dyes the chain to order, so a factory can offer many colours without huge finished stock.
Long-chain winding — winds finished chain into measured rolls for storage, bulk sale or feeding the finishing line.
Testing — pull strength, open/close endurance and slider-smoothness tests catch defects before packing.
Waterproof set — a separate group of machines (film laminating, oven, printing) makes waterproof zipper chain.

Which machines do you actually need?

It depends on the zipper type and whether you start from chain or from finished goods:

Finish only: buy long-chain and run gapping, attaching, stops and cutting. Lowest entry cost.
Full single line: add weaving, teeth-making and dyeing for one material — see how to start a zipper factory.
Multi-material plant: add metal and resin lines; the finishing machines and skills carry over.

Because every machine must work as a matched set, buying the line from one factory-direct maker keeps the timing, sizes and after-sales consistent. See also how to choose a zipper machine supplier.
