According to the material of the zipper, the zipper is divided into three categories: metal zipper, nylon zipper, and resin zipper. Metal zipper teeth are discharged through a tooth-discharging machine using copper wire or aluminum wire. The nylon zipper teeth are composed of a nylon monofilament wound by a heating die, and the resin zipper teeth are colored with a polyester plastic and passed through the dye. The injection molding machine is discharged.
