POM seat recliner
Fenómeno do problema
The clearance of the POM toothed plate of the seat recliner increases after creep
Análise das causas
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
Solução
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
Conclusão principal
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
