Metal zipper, a type of zipper, refers to those with teeth made of copper, brass, or aluminum. Compared to polyester zippers and epoxy resin zippers, they are more durable and are commonly used in denim jeans, outerwear, and messenger bags.

Tape: As the raw materials for metal zipper tapes consist of various types of threads, including polyester filaments, sewing threads, and copper-core cables, their weights and colorfastness differ. This often leads to uneven coloring on the same zipper. Therefore, when selecting the tape, it's important to choose one with consistent coloring and no turbidity. Tapes made from different fabrics are primarily characterized by their soft texture.

Mi齿: The teeth of metal zippers are also colored by electroplating, so it is essential to pay attention to whether the surface stainless steel electroplating is even and free of discoloration when purchasing. Check if the zipper moves smoothly when pulled left and right. After the zipper is closed, make sure to observe whether the top and bottom teeth are properly engaged. Different zipper teeth will inevitably affect the use of the zipper.

Head Pullers: There are various appearances for metal zipper head pullers, and the finished products can be either delicate and intricate or rough and robust. However, regardless of the type of puller, it's essential to check if the pull is easy and if there's any issue with the zipper not being able to close or open properly. Currently, all pullers on the market have an automatic locking mechanism, so after pulling up the zipper, you should check if the lock core is securely fixed before the zipper slides down. Limiting Codes: The left and right stops must be around or clamped onto the teeth, ensuring they are firmly in place.
