As the saying goes, the embankment of a thousand miles collapses in the ant's nest. This principle also applies to luggage customization. A good luggage must be blessed with high-quality luggage accessories. Luggage buckles are one of the basic accessories of basic luggage. If you want to customize luggage with excellent quality The choice of products and fasteners should not be careless, so as not to affect the overall quality of the luggage due to the quality of the fasteners. Now, we have sorted out some items related to the quality inspection of luggage buckles for you to understand together.

There are two main aspects of the buckle in the testing process:

The first is the tensile test, which is mainly to detect the bearing capacity of the fastener. It is divided into two steps to complete:

1. Instant tension test, mainly used for buckle, D buckle, sun buckle, to test the strength of the buckle when suddenly encountering strong pulling force.

2. The main principle of the durable tensile test is to determine the time value of the fastener when a certain weight is loaded.

3. There is also the detection of the number of times of use of the buckle, and it is constantly opened and closed to test how many times the buckle will be deformed.

Three-directional or multi-directional buckle detection is more complicated.

The second is the temperature test, which is mainly to test the bearing capacity of the fastener under unconventional temperature, which is divided into two types: 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

The time is 24 hours, and then the change of intensity is tested.

The third is the salt spray test. This test is mainly to monitor the salinity resistance of the fasteners. Some products can only be transported by sea. Long-term sea operation will affect the quality of the products. This test is also divided into two steps.

1. Soak the buckle in sea water for 72 hours

2. Put the soaked fasteners in the sun for 5-7 days

3. Does the test strength change much after the completion?

There are also some such as acid resistance test, etc., which can be tested according to different needs and materials. Among them, metal fasteners should also be tested for rust resistance, corrosion resistance, drug resistance, etc. If the buckle is subjected to post-processing, such as electroplating, water dyeing, oiling and other processes, it is necessary to further test whether these additional processes are qualified.

Of course, there are higher standard tests applied to extreme sports such as diving. The UL certification, TS16949 certification, and VDA6.0 standard cannot be passed by ordinary fastener manufacturers.
