POM seat recliner
Problem Phenomenon
The clearance of the POM toothed plate of the seat recliner increases after creep
Cause Analysis
The recliner toothed plate bears locking force for a long time, and creep increases the meshing clearance, producing looseness; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select high-rigidity reinforced grades for the toothed plate; metallize the locking structure; verify according to seat durability standards; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Seat locking parts are mainly metal with POM as auxiliary; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
