Zipper Teeth: Zipper Teeth (链牙)
The individual interlocking elements moulded or stamped along the edge of each tape. Tooth shape, pitch and height determine how smoothly a slider closes the chain and how much lateral load the finished zipper can carry. Resin teeth are injection moulded, metal teeth are stamped, and nylon teeth are formed from a coiled monofilament. Consistent pitch and clean edges prevent jamming, skipped engagement and premature wear.
