Cloth belt: Since the raw material of the metal zipper tape is composed of different kinds of filaments such as polyester thread, stitch, and core thread, its component and colorability are different, so chromatic aberration easily occurs on the same zipper. When selecting the tape, you should choose to dye evenly, and there is no turbidity. The tapes made by different fabrics are mainly soft to the touch.

Microphone teeth: The metal teeth of the metal zipper are also electroplated, so you must pay attention to whether the surface plating is uniform or not, and whether there is any color flower, whether it is smooth when pulling up and pulling the zipper. After the zipper is pulled, it must be observed whether the left and right teeth are engaged with each other. The asymmetric zipper teeth will definitely affect the use of the zipper.

The slider: the metal zipper pulls more shapes, and the finished product can be small and delicate, and can also be rough and majestic. However, no matter what kind of slider, it is necessary to feel whether the pull of the slider is free, and whether the zipper can not be pulled or closed. Nowadays, the sliders on the market are equipped with self-locking devices, so after pulling the zipper, it is necessary to check whether the zipper will slide down after the lock is fixed. Limit code: the upper and lower ends must be fastened to the microphone teeth or clamped on the microphone teeth, which must be guaranteed to be perfect.
