Springs can be said to be something that we can generally see in our lives, so why do springs suddenly break during use? There are mainly the following reasons. Let's take a look!

1. The mandrel is too small or the spring is placed horizontally, and the spring and mandrel are worn and broken.

2. When the mandrel is too small / the assembly surface is not flat / the parallelism of the positioning surfaces at both ends is poor, the spring will be compressed and twisted, and high pressure will be locally generated and broken.

3. The mandrel is too short and the end is chamfered, which will cause friction and wear between the spring and the mandrel and break.

4. The use of foreign matter between the spring coil and the coil reduces the actual effective number of coils, thereby generating high stress and causing it to break.

5. The spring is used in series to make it bend and exceed the length of the mandrel or counterbore, or the weaker load will break due to the small difference in the spring itself.

6. Use over a large amount of compression to produce high-effect force to break the spring.
