What are the quality inspection items for luggage buckles -? Pesin Outdoor Products Company
As the saying goes, the embankment of a thousand miles breaks in the ant hole. This principle is also applicable to the customization of bags. A good bag is indispensable for the quality of the luggage accessories. The luggage buckle is one of the basic accessories of the basic luggage, if you want to customize luggage products with excellent quality, the choice of fasteners should not be careless, so as not to affect the overall quality of luggage due to the quality problems of fasteners. Below, Pesin Outdoor Products Company has sorted out some items related to the quality inspection of luggage fasteners for everyone to learn about. There are two main aspects in the test process of the buckle: one is the tensile test, which is mainly to test the bearing capacity of the buckle, and it is divided into two steps to complete: 1. Instant tensile test, mainly used for buckle, D Buckle, Day buckle, test the strength of the buckle when suddenly encountering strong tension. 2, long-lasting tensile test, its main principle is to determine the time value of the buckle when the load is a certain weight. 3, on the buckle and the number of times of use of the test, keep opening and closing, to test how many times, the buckle will be deformed. Three-direction or multi-direction buckle detection is even more complicated. The second is the temperature test, which is mainly to test the bearing capacity of the buckle at unconventional temperatures, it is divided into high temperature and low temperature. 1. The high temperature is usually set at 70 degrees Celsius. 2. The low temperature is usually set at minus 30 degrees for 24 hours. Then the strength change is tested. The third is salt spray test. This test is mainly to monitor the anti-salinity of the buckle. Some products can only be transported by sea, and the long-term operation at sea will affect the quality of the products, the test is also divided into two steps. 1. Soak the buckle in seawater for 72 hours. 2. Expose the soaked buckle to the sun for 5- 7 days 3. Has the test strength changed too much after the completion. There are also some, such as acid-proof tests, which can be tested according to different requirements and materials, among them, the metal fasteners should also be tested for rust prevention, corrosion prevention, drug resistance, etc. If the plastic fasteners are processed after the product, such as electroplating, water dyeing, oil smearing and other processes, further testing is required to determine whether these additional processes are qualified. Of course, there are higher standards of testing for extreme sports such as diving, what UL certification, TS16949 certification, VDA6. 0 standard, it is not the general buckle manufacturers can pass.
