PA66 throttle body
Fenómeno do problema
Throttle body dimensional drift causes unstable idle
Análise das causas
PA66 moisture absorption expansion changes valve bore dimensions, and precision fitting clearance drift affects intake control; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Solução
Select low moisture absorption grades or dimensional compensation design for precision throttle bodies; moisture conditioning after molding then precision machining; full-temperature full-humidity range verification; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Conclusão principal
Precision airflow control parts require low moisture absorption materials or compensation design; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
