The key to the production of metal zipper is its electroplating process, which will directly affect the final quality and performance of the zipper, so it should be carefully operated. After the metal zipper is formed, special chemicals need to be used for electroplating to obtain the desired zipper color. If the zipper is made of different materials, the effect after electroplating treatment will also be different. Even if it has been electroplated, but because the coating is very thin, the nature of the zipper is still not stable. Therefore, it is generally necessary to pass the oil on the chain teeth during the ironing process, which is done in order to achieve good acid and alkali corrosion resistance and oxidation resistance, and also helps to adhere to the color. The metal ring on the zipper is different from the teeth when it is treated on the outside. It is completed by hanging plating process, and then a protective film that will not fade on the outside is used to adhere to the quality of the metal ring.
The metal zipper belongs to a kind of zip lock, which refers to the zip lock whose teeth are made of copper, white copper or aluminum. Compared with nylon zippers and resin zippers, it is more firm and used for jeans, outerwear and crossbody bags. Scientific application of metal zipper: 1, when driving the metal zipper, be sure to first close the teeth on both sides, the top must be aligned, and then pinch the metal zipper head along the track gently, can not pull too hard. 2, when moving the metal zipper head, be careful not to twist clothes or cloth edges and other debris into the metal zipper, to prevent "teeth tilt", "broken belly", "teeth" and other conditions.
The metal zipper has different adaptability in different environments in the process of use, so in the process of selection, it is necessary to propose to the manufacturer that the metal zipper needs to be used in that type of product, such as its poncho, tent, boots, skating clothes, and washable jeans. Metal zipper teeth black or discolored teeth in the process of use will lead to its fabric pollution, in the use of copper alloy once its oxidation will be black, the bag should not be sealed, the use of the process needs to maintain its ventilation.
Metal zippers belong to a zipper, which refers to zippers whose teeth are made of copper, white copper or aluminum, which are more firm than nylon zippers and resin zippers, and are mostly used in jeans, coats and crossbody bags. Metal zipper selection, cloth belt: because the raw material of metal zipper cloth belt is polyester silk, sewing thread, core thread and other different kinds of silk, its weight, color are different, so it is easy to produce color on the same zipper, then choose the color symmetry when choosing the cloth belt, no turbidity point, the cloth made of different fabrics are soft to touch.
