The Fashion Zipper is considered to be one of the top ten inventions that make people's lives easier in modern times. A zipper is a fastener consisting of a row of metal or plastic teeth on two straps, which is used to connect the edge of the opening. A slider can pull the two rows of teeth into the interlocking position to close the opening. At present, the more commonly used zipper types are Brass Zipper, Waterproof Nylon Zipper, Nylon Zipper , Plastic Zipper, Jeans Pants Zipper and so on. The use of high-quality zippers can improve the quality of clothing and maintain the reputation of the company. Therefore, as a zipper supplier, we should attach importance to the quality management of Brass Metal Zipper and better serve customers.

The quality management of Metal Zipper includes many aspects, the first is about the specifications and types of metal zipper. The specification refers to the width scale and scale scale of the two tooth chains after the teeth are joined, and the unit of measurement is millimeters. The specification of the Jeans Zipper is the basis of the shape scale of each component, and it is an important scale with characteristics. The type of zipper is an important reflection of the shape, structure and functional characteristics. It not only contains the zipper specification requirements, but also reflects the zipper function characteristics, that is, the zipper technical parameters and application functions.

Followed by the strength of metal zipper. This is the main function index, which determines the scale and degree of use of the zipper. Different types of zippers have different strengths, and their uses are different. Zipper suppliers usually give a reference selection of the type and scale of application.

Clothing must be fitted with a zipper of the correct length, so metal zipper length measurements must be accurate. The way to measure the length of a zipper is to lay the zipper flat on a flat plate so that it is in a natural state, and use a steel ruler to measure from the top of the slider. In the manufacturing process of metal zippers, due to the inertia of the equipment and the integrity of the fastener elements, the length of the zippers allows slight errors, but it must be within a certain range.

The test method for the straightness of the metal zipper is to take a finished zipper and lay it flat on a flat table so that it is in a natural state; then use your fingers to move back and forth along the sides of the edge of the fastener element and use a ruler to gradually bend to the bend Get close to each other, and then use another ruler to measure the distance between the chain feet and the ruler. This interval is the flatness.
