Metal zippers are popular because of their durability. Metal Jeans Zippers can be found on jeans, thick coats, bags and more. The Fashion Jeans Zipper is composed of a cloth tape, a microphone, a slider, and a limit code. Since the raw material of Jeans Zipper tape is composed of different types of silk, such as polyester threads, sutures, and core wires, their components and coloring properties are different. Therefore, color difference is easy to occur on the same Jeans Pants Zipper. When you choose to dye evenly without turbidity, the fabrics made of different fabrics are mainly soft to the touch.

The teeth of the Brass Metal Zipper are also plated and colored, so when buying, you must pay attention to whether the surface is plated uniformly, whether there is a phenomenon of blooming, and whether the zipper is smooth when moving up and down. After the Custom Brass Metal Zipper is closed, you must observe whether the left and right teeth are engaged with each other. Asymmetric zipper teeth will definitely affect the use of the zipper.

Electroplating of metal zippers is a chemical reaction, not an electrolytic reaction. Different copper materials have different chemical reaction effects. At present, H85 and H65 copper materials are the more commonly used raw materials. H90 copper is generally used when pursuing high brightness effects, such as rose gold.

Because the chemical plating is only a thin layer, and its properties are unstable, it is generally necessary to pour the oil on the chain teeth during the ironing process, so that it can maintain color, and prevent acid and alkali corrosion and oxidation. For aluminum or copper zippers, be careful not to get wet during use and storage, and avoid contact with alkaline and acidic substances, so as to avoid metal teeth from being oxidized and corroded.

The upper and lower stops of the Metal Zipper's limit code must be fastened to the teeth or clamped on the teeth. It must be strong and perfect. There are many shapes of Metal Zipper Sliders, and the finished product can be either small and detailed, or rough and majestic. However, no matter what kind of slider, you must feel whether the slider can be opened easily. Will the zipper fail to close or close? The zipper heads currently on the market all have self-locking devices, so after pulling the zipper, you must check whether the zipper will slide down after the lower lock head is fixed.

Electroplating makes our zippers have beautiful colors and gloss, but in daily use, we should also pay attention to the protection of the zippers to make them longer.
