Quality Journey: Transformation from Raw Material to Finished Product
The birth of metal zippers began with the careful screening of raw materials. High-quality brass or stainless steel is the foundation, and special alloys are added to increase durability and rust resistance. This journey begins with ore extraction, through high-temperature smelting, cooling and casting, until a tough and smooth metal wire is formed. Every step must follow strict process standards, so that the metal zipper has impeccable texture and strength.



Source of Excellence: Selection and Quality of Raw Materials
The reason why metal zippers can stand out in many materials is inseparable from the metal composition and its unique properties. For example, brass is widely used for its good ductility and wear resistance, while stainless steel is favored for its excellent corrosion resistance. In addition, the introduction of some high-performance alloys such as nickel silver and aluminum alloys has further improved the overall performance of metal zippers, making them suitable for more demanding environments.
Craftsman's Handwork: The Art of Fine Processing
The manufacture of metal zippers is far more than mechanized production, which also combines a lot of manual operation and exquisite skills. From the precise grinding of the tooth shape to the fine assembly of the slider, every detail tests the patience and skills of the workers. Not only that, the color painting of the zipper also requires the meticulous operation of the craftsman to ensure a uniform and lasting color. In this process, experienced masters give vitality to the cold metal with their keen eye and skilled hand.
The ultimate pursuit: strict standards for quality inspection

Tensile test, sliding smoothness inspection, durability test... Each data records whether the metal zipper meets the expected standard. Only those zippers that perform well in all indicators can be finally packaged and stored, waiting to be sent to customers around the world.
