​Why does the spring break during use? The following spring manufacturers give you a brief introduction.

1. If the mandrel is too small or the spring is used horizontally, the spring and mandrel will wear out and break.

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 not chamfered, which will cause friction and wear between the spring and the mandrel and break.

Why does the spring break during use?
4. The use of foreign matter between the spring coil and the coil reduces the actual effective number of coils, resulting in high stress and breaking.

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. The use of exceeding the maximum compression will produce high-efficiency stress to break the spring.

7. The spring material is uneven, or the impurity content exceeds the standard, resulting in stress concentration fracture.

8. The spring is overburned, rusted, hardened, and overextended will reduce its tensile and compressive strength and cause fracture.
