The production of metal zippers involves intricate engineering steps

The production of metal zippers involves intricate engineering steps. First, metal coils (brass, aluminum, or nickel) are fed into machines that stamp and cut them into individual teeth. These teeth are then precisely attached to fabric tapes using specialized riveting or soldering techniques. The slider, a critical component, is crafted from metal alloys for smooth gliding, with precision-ground edges to prevent snags. Quality control includes tension tests to ensure teeth alignment and durability checks under repeated use. This meticulous process ensures each metal zipper meets strict standards for strength and performance.
