As the supporting structure of the umbrella, the material and strength of the umbrella bone determines the durability and windproof performance of the umbrella. Whether the umbrella bone is made of stainless steel, aluminum alloy or fiber, it is necessary to check whether the surface is smooth and burr-free, whether there is any crack or deformation, and it is necessary to carry out a load-bearing test to ensure that it will not be easily broken under normal use.

The first thing you can do is to conduct a waterproof performance test. Hold the umbrella open to simulate a rainfall environment with a specified amount of water and water pressure, and observe whether there is any water penetration on the surface of the umbrella. The abrasion resistance test is conducted through a specific friction instrument, rubbing the umbrella surface several times to see whether the surface is hairy and broken. For the strength test of the umbrella bone, professional mechanical testing equipment is used to gradually increase the load, record the value when the umbrella bone breaks, and determine whether it meets the standard. Function test is mainly for the opening and closing performance of the umbrella. For manual umbrellas, check whether the opening and closing process is smooth, whether the umbrella bone can be completely open and locked; automatic umbrellas in addition to testing the sensitivity of the opening and closing, but also to check whether the spring resilience is normal, whether the button is durable. At the same time, simulate the actual use of the scene, test the stability of the umbrella in different angles of opening and closing.
