1. Analysis of poor rebound:
1) Over travel can cause rebound
2) Excessive pressure
3) The shrapnel itself is under force
4) If there is any tapping during the assembly process and static electricity is picked up by the shrapnel, pressing it again can also cause the shrapnel to reverse
5) Excessive load
2.Solution:
1) Ensure that there are no issues with the performance testing of the shrapnel - load, rebound, and stroke confirmation
2) Solve the static electricity problem during the assembly process, add and remove the static motor, and use anti-static materials.
The customer's shrapnel should not be pressed too hard during use.
