In the overall use of hardware springs, there are several kinds of elasticity shortages:
1. hardware springs in the design of production parameters did not meet the standard, resulting in insufficient springs.
2. The corresponding spring is not used in the standard temperature, resulting in insufficient spring elasticity.
3, when using the metal spring, it is wrong to use the ordinary spring action high-quality spring, all resulting in insufficient elasticity.
4. The corresponding spring type is not used in pressure, resulting in insufficient spring elasticity.
5. hardware springs did not pay attention to a good time difference in the processing, so that the spring quenching time is insufficient, resulting in insufficient quenched elasticity.
