Stamping
Forming metal teeth and slider bodies with progressive dies; die clearance controls burrs and accuracy.
The Topics section gathers zipper and garment accessory selection guides, craft analysis, and industry standards, helping designers and buyers quickly find suitable trim solutions.
Forming metal teeth and slider bodies with progressive dies; die clearance controls burrs and accuracy.
Polyamide 66 with higher melting point and strength than PA6; used for monofilament and heat-resistant parts.
Light alloy for teeth and sliders; anodising gives colour and corrosion resistance but strength is lower than brass.
Zipper made from a coiled nylon monofilament sewn to the tape; flexible, light and corrosion resistant.
Zipper with teeth hidden behind a folded tape edge; gives a clean seam on dresses, skirts and furnishings.
Semi-finished two-tape assembly with teeth attached, supplied in rolls and cut to length for finishing.
Removing burrs and scratches from metal parts before plating; a smooth substrate improves adhesion and gloss.
Zipper with POM teeth moulded directly onto the tape; uniform, rigid, colourful and corrosion resistant.
Slider blockage caused by uneven pitch, burrs or trapped thread; forcing it can break teeth.
Copper-zinc alloy for stamped metal teeth; strong, formable and takes plating well.
US law regulating products for children; limits lead, phthalates and small parts and requires testing.
Tooth rows that fail to line up when closed; caused by uneven tape, twisted sewing or wrong slider size.
Resistance of a closed zipper to splitting when the tapes are pushed apart; shows interlocking and slider grip.
Zipper with stamped metal teeth; strong and premium looking, used on denim, leather goods and heavy bags.
International hydrostatic pressure test measuring water penetration resistance of fabrics and waterproof zippers.
Interlocking elements fixed along each tape edge; tooth shape and pitch control smoothness, strength and service life.
Maximum force resisted by a locked slider before the chain opens; measures self-locking reliability.
Chemical deterioration of metal parts showing as discolouration or rust; linked to plating porosity.
Maximum force a closed zipper withstands in the tape plane; key indicator for load-bearing openings.
Force required to pull a slider off the chain; indicates how securely the slider grips the teeth.
Depositing a metal layer on zipper parts for colour and corrosion resistance; adhesion and thickness are critical.
Wavy or puckered seam along a sewn zipper; caused by shrinkage mismatch and excess sewing tension.
Number of open and close cycles before failure; a combined measure of durability and wear resistance.
Copper-nickel-zinc alloy with a silvery finish and better corrosion resistance; used on premium metal zippers.
Reinforced part at the upper chain end that blocks the slider; holding strength prevents the slider from running off.
Low-melting alloy for die-cast slider bodies; flows well into thin moulds and takes plating.
Colour variation between different production lots; controlled by shade grouping and lot traceability.
Independent textile certification for harmful substances; zippers must meet class-specific limits.
Zipper with teeth woven directly into the tape edge; soft, flat and free of stitch lines.
Tab attached to the slider for gripping; must balance handling comfort, pull-off strength and safety compliance.
Heat treatment that relaxes stress and stabilises tape dimensions; key to preventing shrinkage and waviness.
Cracked or snapped tooth, often at chain ends or where a needle struck; causes jamming and sharp edges.
Zipper with two opposing sliders that open from either end; used on long coats, sleeping bags and luggage.
Colouring tape or chain to a customer standard; temperature, concentration and pH control shade and fastness.
US test methods for zipper strength including pull, tooth, stop and slider pull-off tests.
Zipper permanently joined at the lower end by a bottom stop; common on trousers, skirts and bags.
Global Recycled Standard verifying recycled content and chain of custody; transaction certificates are required.
Fabric strip that carries the teeth and provides the sewing margin; density, width and shrinkage control stability.
Thermoplastic polyurethane used for waterproof film and coated tape; flexible, tough and bonds well to fabric.
Process of injecting molten plastic into a mould to form resin teeth and stops; controls size and bond quality.
