The Zipper Test: Why Your Hardware Is the “Silent Brand Killer”

In my two decades in this industry, I’ve learned one hard truth: a customer will forgive a loose thread, but they will never forgive a broken zipper. Hardware failure is the #1 reason for “dead stock” and consumer frustration. If the teeth don’t mesh or the puller snaps off in their hand, your brand’s luxury status vanishes instantly. 

At CdGarment, we treat hardware as engineering, not just decoration.

5 Critical Checks for High-Performance Hardware

1. The Lateral Strength Test: Cheap zippers burst open when the wearer sits down. We only source zippers that pass a “Crosswise Strength” test of at least 250N.

2. Oxidation Resistance: If you’re shipping by sea, salt air can corrode “pot metal” zippers before they even reach your warehouse. We use hardware with a double-layered anti-oxidation coating.

3. The “Safety Snap” Pull Force: For children’s wear and high-end activewear, our snap buttons are applied with a calibrated pneumatic press, ensuring a pull-out force of >90N to prevent detachment.

4. Self-Locking Technology: There is nothing worse than a zipper that slowly slides down on its own. Our “Auto-Lock” sliders contain a tiny internal spring-pin that keeps the zipper exactly where the customer wants it.

5. Polished Teeth Geometry: Low-grade zippers have sharp, unpolished teeth that snag the fabric or scratch the wearer’s skin. Every metal zipper at CdGarment is tumbled in a polishing drum for 4 hours to ensure a “butter-smooth” glide.
