Hardware accessories including zippers, buckles, rivets and hanging rings are small parts that determine the overall durability and service life of bags. As an ISO9001 certified formal bag factory with 12-year manufacturing experience, Colefa implements strict professional durability testing for all matched hardware parts before mass production. The first test is tensile resistance test. Professional equipment pulls buckles, straps connection parts and metal accessories with fixed force to verify whether they are loose, deformed or broken, ensuring safety during daily carrying and heavy loading. The second test is salt spray corrosion resistance test, simulating humid, rainy and coastal high humidity environment, detecting anti-rust and anti-oxidation ability of electroplated hardware, avoiding surface rust and color fading after long-term use. The third test is friction resistance test, repeated rubbing hardware surface to check paint peeling and scratch situation, guaranteeing long-term beautiful appearance. Zipper smoothness and service life test is also essential, conducting thousands of opening and closing tests to confirm no jamming, tooth falling and sliding failure. All hardware accessories that fail to reach the standard will be eliminated directly. We select high-quality zinc alloy, stainless steel and environment-friendly plastic hardware materials, match different hardware styles according to bag positioning from daily casual bags to high-end customized bags. Strict testing standards reduce after-sales quality problems, help buyers obtain stable qualified products and maintain good market reputation.
